Here was the spark that finally spurred me to action this morning.  And I’ve seen this before but it just hit me particularly wrong this morning:

RESTART!!!!  You got to be kidding!!!  Why the Hell do I have to restart?  All I did was update a viewer, really just a plugin for a browser.  Adobe, do you have any idea how long it takes my work computer to restart?  What could be so important that you’re making me reboot?  If it’s such a pain for me, it’s most likely a pain for other people too.  Have you considered the irritation you’re causing everyone?

The Solution: Foxit

Okay, I’ve had enough.  I uninstalled Adobe Reader, and I installed a replacement product that my friend Brandon recommended called Foxit.  http://www.foxitsoftware.com/pdf/reader/

• My first worry was that it doesn’t work with my browsers.  However, that worry was unfounded.  I tested pulling up a PDF from a URL in IE8, Firefox, and even Chrome (my browser of choice).
• My first observation was the speed.  It was so much faster than Adobe.  (Didn’t Adobe invent PDF’s?)
• Plus, the Interface looks pretty refined and easy to use.
• Foxit install is 10.44 MB versus Adobe Reader 9.3 at 143 MB

I don’t completely endorse the product because I haven’t had substantial time using it, but so far I like it.   The main thing is that I got a chance to pwn Adobe!  Take that you bastards!

I was in the middle of making a rather lengthy comment on Daniel’s most recent blog post when I decided it was long enough to warrant a full posting.

I wanted to get across the point that the situation Daniel finds himself in is not solely the plight of the software tester. Rather, anyone who esteems software quality runs the risk of being criticized, dismissed, or made fun of. Why is it that organizations and groups are so resistant to something that will improve their process, their product, and their bottom line. The idea is one I have been thinking a lot about, and I believe I have had an epiphany.

Sometimes, people are more afraid of success than failure!

Wait… what did you say?!? You heard right, and I’ll say it again. Sometimes, people are more afraid of success than failure.

I recently gave a presentation where I cited the Microsoft study on TDD that found:

The results of the case studies indicate that the pre-release defect density of the four products decreased between 40% and 90% relative to similar projects that did not use the TDD practice. Subjectively, the teams experienced a 15–35% increase in initial development time after adopting TDD.

The idea that up to 90% of your test and fix cycles can be eliminated represents an enormous cost savings even if you factor in the high end estimate of 35% increase in initial development time. You will more than make that time up by not having to fix the 90% of bugs that are now gone from the system. With numbers like that you would think that management would be breaking people’s knuckles for not using TDD. Developer’s would be falling over themselves to TDD even the smallest spec of code just to avoid doing maintenance (curse the ground that software maintenance walks on).

But alas, there was no stampede. No rush to go forth and test. No proclamation from management that it must be so. So… what gives?

What gives is that it might just work! Developers might just write cleaner code, and be more productive. Testers might be able to confirm code quickly and have the freedom to explore automated acceptance testing. Deadlines might be met, and the company might save money. And… and… we might have to admit that we have been doing it all wrong for a very long time.

And there it is; the big white elephant in the room of software quality. Not fear of failure, but fear of success. Because success means having to admit things can and should be better. Even worse, that they could have been better all along. And we don’t like that. Most of us like to think we are pretty smart, that we are pretty damn good at what we do. When someone shows us a better way, our little bubble bursts, and we are forced to admit that we aren’t as special as we’d like to think we are.

The mediocre will always defend the status quo because their sense of worth is derived from being the smartest, funniest, sexiest, whateverist person around. They are a big fish in a little pond, and they like it that way.

The exceptional are never satisfied with the quality of their own work. They assume that there must be a better way, and seek out the best and brightest in the world to learn from. They draw their sense of worth from knowing they are better today than they were yesterday.

Exceptionalism is the arch-enemy of mediocrity, and success is it’s kryptonite!

I was very impressed by the people that attended the talk.  They were all software developers and highly technical. Plus, they all seemed interested in testing.  (Of course, when I pulled out the candy, people got even more interested.)  I was glad to have an audience that challenged, asked questions, and made terrific observations and points.  People mentioned technologies they used.  They talked about patterns and approaches, citing real world implementations.  As I speaker, I couldn’t ask for more.

Not one person from my current company came to the presentation, though I informed everyone through email with notice.  That seems reasonable.  The presentation was downtown KC (our company is 25 mins away in the suburbs); someone would have had to be very interested in coming to want to go.  Either that or really owe me a favor (i.e. I went to one of their presentations or baby sat for their kids).  I wasn’t shocked that no one came.  What I was shocked about was how few people replied to wish me luck or asked me about it.  This is after I sent out an email with the phrase, “I’m presenting on Exploratory Testing tomorrow, April 27^th at 7:00 pm at the DotNext meeting.  Wish me luck.”  Three people out of 30 wished me luck.  And one guy asked me about it the next day.  That tells me that people don’t care.  And they don’t even care about faking to care.  What does that tell you?  Two groups of software developers: one group wanted to listen (total strangers) and one didn’t want to condescend interest (people I know).

Jesus said to them, “A prophet is not without honor except in his hometown and among his own relatives and in his own household.” (Mark 6:4)

Most of the time, QA people don’t get the respect they deserve.  Working with my colleague Marisa  at Edfinancial, QA was well respected and not seen as the pariahs of the group.  Most organizations don’t respect their QA prophets.  We, the prophets, tell them that their shortcuts are going to bite them in the butt.  We tell them that standards and sound process will help things, and they don’t believe us.  We tell them that bugs need to be fixed and defects are dangerous, and they don’t listen.  No only will they not listen, but they also want to stone us and run us out of town.

My question is where do you, as a QA prophet, draw your purpose and satisfaction?

Here’s the part that I give the answer, right?

Wrong.  I don’t have the answer.  All I know is that it’s probably something intrinsic.  I think that will and desire have to come from within.

If you are a little lost by the title, it will all make sense in a moment… um… sort of.

Until I started my career as a software developer I worked a lot of other jobs. I have had a job since I was 16 years old, and that was just an excuse to get out of doing manual work for my parents around the house. I’ve worked as a bagger at a grocery store, cashier at a big-box-mart, usher, concessions, and box clerk for a movie theater, tech support for a DSL provider, general laborer for a masonry outfit, and the last job I worked before slinging code full-time was waiting tables.

All of these jobs really have one thing in common: I was the person who always caught the tail end of the customer’s experience: whether it was good or bad… especially when it was bad!

Waiting tables is an interesting experience, and one I think everyone should have to do at least once in their life. As a waiter you are the face of the dining experience for the customer. Before the customer even gets there, you are preparing the store to make their time enjoyable. You clean the kitchen, wash dishes, stock pantry items, napkins, silverware. You go over your section to make sure that everything is set up correctly and clean.

Once a table in your section has been seated, as far as the customer is concerned, you are the restaurant. You size up the customer to figure out what kind of approach you should take (believe me it makes a difference). You give them an overview of the menu, get their drinks, throw out a couple of suggestions, and meticulously write down the order  making double sure to repeat back the order so there are no misunderstandings. Without delaying, you ensure that the order is put into the computer accurately and check to see that the kitchen staff gets the ticket. If needed you even explain any nuances of the order to the cooks: “‘SUB BAKER ADD CHEESE.’ Hey Joe, they want a baked potato instead of mashed, and they want to add cheese to the sandwich, NOT the baker!”

While waiting for the food you are feverishly busing, washing, and resetting tables for the next set of patrons that walk into your section; you make sure they think they are the first people to sit there. A single spec of food left on the table or the floor can ruin the whole meal! Every time you walk into the kitchen you are checking the status of your food.

“307 IN THE WINDOW!”

Your order is up and now you are checking every detail to make sure the food you have matches the ticket. You tidy up the presentation a little and make sure the plates are picture perfect. Drop the food off to the table and make sure they have everything they need: drink, condiments, extra napkins, steak knives, etc… You let the table dig in and about two minutes later you come back to make sure everything was up to par. You never take them at their word either! You have to actually look at their plates, and their faces to see if they are telling the truth. Most people are too sheepish to tell you everything sucks, and they will simply not come back to the restaurant if the experience is bad. It is up to you to see this and recover their patronage.

Ok. So what? Why waste your time with this?

Because QA and waiting tables have a lot in common. As QA, you are the standard bearer for a quality user experience much the same way that a waiter is the standard bearer for a quality dining experience. In order to really be effective you have to be involved in the process from start to finish. You need to be there when the user story is first conceptualized in order to effectively develop a testing strategy. You need to determine the set of criteria by which a story can be considered done (acceptance criteria). You also need a repeatable way to ensure the story as coded meets those criteria (Fit/FitNesse, StoryTeller, Selenium).

As the story is being developed you need to be in constant communication with the developer (cook) to make sure that any misunderstandings are cleared up immediately. Developers make assumptions if the acceptance criteria are vague. So find out what those assumptions are, and refine your acceptance tests accordingly. Be proactive about communicating your testing strategy to the developer(s) working on the story so they won’t be tempted to just throw it over the wall. A good developer will make your job easier here, but good acceptance tests do NOT care how well written the code is. Remember that your main goal is not to find bugs, but to verify that the feature/product will meet the customers needs. An acceptance test that fails is not a bug, it is simply an incomplete feature, and we don’t ship incomplete features.

Being a QA professional takes a lot of discipline and involves a lot of responsibility, but it is your job as a professional to demand software quality above all else. A professional will stand on principle in this area while an amateur will make excuses for the level of quality… “I don’t have enough time to do automated testing! The developers write bad code! My boss doesn’t appreciate QA!”… All those things may be true, and may make it harder to do your job, but it doesn’t change your job!

QA can be a tiring and thankless job, but the professional derives pleasure from a job well done. Be committed to the project/story/user, and not your own hide. This is what separates “testers” from Software Quality Professionals. This is the difference between a great user experience and a mediocre one.

The meal is over, and the customer is satisfied. On their way out the table says “The meal was excellent! Be sure and thank the cook for me,” as they hand you a three dollar tip.

“I’ll do that sir!” You say with a smile, knowing that you did your job. You made sure that everything was perfect. You took care of all the grimy little details so they could concentrate on what they came there for… a good meal.

Déjà vu all over again! Another basic Selenium example. What the heck!? Can’t this guy do anything else?

Well, I agree this is somewhat repetitive, but I hope that this sequel will be in the league of Empire Strikes Back or Star Trek: The Wrath of Khan. Both movies, though they were sequels, were arguably greater than the originals. These sequels introduce us to the likes of Ricardo Montalban playing “Khan” and Billy Dee Williams playing “Lando Calrissian”.  And of course,  a muppet playing “Yoda”.

Of course, many sequels start off with the desire to be Empire, and instead they end up being:

• Caddyshack II
• Beastmaster 2: Through the Portal of Time
• Speed 2: Cruise Control
• Batman and Robin (No, we don’t need nipples on the Batman suit, Joel Schumacher.  But thanks for asking.)
• Mannequin: On the Move.
• Or the biggest sacrileges of all time Godfather III
• And Episode I (Empire, it is not!).

My hope is that this post doesn’t suck like those movies.  At the very least it’s nipple and Clooney free.

• Selenium RC
• Firefox
• Selenium IDE
• Java Runtime Environment (You should already have this)
• Visual C# 2008 Express Edition (Only get this if you don’t have a full version of Visual Studio)

Selenium RC
-No installation necessary. Just find a permanent location and unzip it there. I unzipped mine at C:\ just to make things simple

Firefox, Visual Studio Express, and Java
-Just run the respective installs with all defaults selected.

Selenium IDE
-To install, right click on the file and select “Open With…”
-Select Firefox in the programs list. If it’s not in the immediate menu, browse to it. (default location should be “C:\Program Files\Mozilla Firefox\firefox.exe“
-When Firefox launches, click button in the dialog box that says “Install Now”.
-After the install of the plug-in, hit the “Restart Firefox” button when you see it.

Okay, so, now that you have the tools, we’re going to record a simple test in Selenium IDE. Even though we want to eventually run the test in Selenium RC, Selenium IDE is a great tool for getting the basic test recorded since it’s all UI point and click.

• Start up Firefox.
• Click on the “Tools” menu and click on “Selenium IDE”
• (Take your time to explore the Selenium IDE form)
• Notice that it’s already recording.  The red circle button on the right side is pressed in:
• Type “www.google.com” the main Firefox browser address bar and navigate to it.
• In the search box, type in “thetestingblog.com” and hit the “I’m Feeling Lucky” button.
• Notice in your Selenium IDE window that steps are being recorded.
• With any luck, you hopefully landed on this blog’s home page.
• Highlight the text “Daniel Brown” on the page, right click.  You should select the option that says “VerifyTextPresent Daniel Brown”.  See below:

• Okay, we got our test recorded.  Now let’s run it to make sure it passes.
• Unclick the red circle button to turn off recording.
• Click on the green play triangle with the single bar to run the test

• All green, it passed.  Good.
• Now we want to convert this test to C#.
• Select “Options ->Format -> C# – Selenium RC” from the Selenium IDE window.

• Next select all the C# code and copy it.

• Open up Visual Studio
• Select “File ->New ->Project”
• In the New Project window under project types, select “Visual C# ->Windows”
• Select the “Console Application” Template and name it something like “TestingBlogSeleniumTest” and click “Ok”.
• It will create the project along with a file called “Program.cs”. Paste your SeleniumIDE test into Notepad. You’re going to take pieces out of the test and put it in “Program.cs”.

1. Add the using references from the SeleniumIDE test.  Replace any that are there.
2. Add the “ISelenium” and “StringBuilder” object references inside the Main() method.  As you see, I removed the “private” access control prefixes.  We don’t need them.
3. Add the body of the SetupTest() method after the object references.  (I put a comment to designate that it was part of the setup.)
4. Change “*chrome” to “*iexplore” for Internet Explorer.  Use “*firefox” for Firefox.  (There are other browser options, but those work best.)
5. Change the URL to the site you start your test on.  In this case, change that URL to “http://www.google.com/” since we’re starting from Google.

6. Paste body of the TheUntitledTest() method into the Main() method.

7. Paste body of the TeardownTest() method into the Main() method.

8.  Get rid of the Try/Catch blocks on Teardown.

9. Get rid of the StringBuilder references.

10.  Get rid of the Try/Catch block in the test body, replacing it with an if statement that writes to the console window if true (See my code below).  Notice that I have to cast the Selenium.IsTextPresent statement as a boolean.  I don’t understand why it doesn’t work without it because the return type for that method should be boolean.  But whatever.  I’m just dummy tester; what do I know?

• Next we need to add all the references so this thing will run.
• Go to the solution explorer, and right click on the “References” and select “Add Reference…”
• Hit the “Browse” tab and navigate to where you unzipped your SeleniumRC files.  Look in the dotnet client driver folder.  Here’s the path to mine:

C:\selenium-remote-control-1.0.1\selenium-dotnet-client-driver-1.0.1\

• Once you navigate to where the proper *.dlls are, select all of them and click “OK” to add them to the project.  (I know you can probably get away with adding less, but let’s keep it simple.)

• Build the project to see if it works.  (Mine worked.  Hopefully yours did too.)

• In order to run the Selenium RC test, you first have to have the Selenium RC server running.  The Selenium RC server folder should be in the files you unzipped.  Normally, I have a batch file on my desktop created to run the Selenium Server, but for our purposes, we’ll just run this from the “Start -> Run” commandline, using this command:

java -jar C:\selenium-remote-control-1.0.1\selenium-server-1.0.1\selenium-server.jar

• You should see some a dos window popup, and you will see something like the screenshot below.  DON’T CLOSE IT WHILE TESTING; IT NEEDS TO STAY RUNNING.  If you don’t have Java installed, this won’t work.  But most people should already have Java.

Next you need to select Debug from your Visual Studio menu and select “Start Without Debugging”. (I’m choosing this option because it doesn’t close the console window after the end of execution.  The debug option does.)

You should see the Selenium window(s) pop-up.  And it should do it’s thing.  When it’s finished, you should see something like this:

So, where is my test executable?  Well, it’s in the bin\debug folder of the project.  For me, the path to it looks like this:

C:\Documents and Settings\dbrown\My Documents\Visual Studio 2008\Projects\TestingBlogSeleniumTest\TestingBlogSeleniumTest\bin\Debug\

So, what do I need to run the program?  Just take the executable file and the dll’s.  Make sure the dll’s are in the same folder as the test when you execute it, otherwise you will get a big fat error.  If you send the executable to someone, make sure you send the dll’s too.

Remember if you port that executable to another computer, it needs to be a Windows box with the .NET framework installed and Selenium server needs to be running.  I hope this actually helps someone.  I’m going to post some tricks to “sex up” your console app.  Be looking for them shortly.

Sorry, I still haven’t figured out Selenium GRID good enough to post on it.  Maybe Marisa could post on it?  She’s awesome like that.

Then something happened one day!  A fob became available.  As soon as I got the email, I replied to all claiming my stake over the available fob.  Much to the chagrin of the office admin, who seems to have a problem with me, I ended up with the fob!  But she wouldn’t let me physically have it until the registration is changed over in the system.  That should take a day.  I was fine with that, but I shouldn’t have been.  The whole reason for having electronic systems is so that things can happen instantly.  Well, maybe it’s not the system itself.  Maybe it’s the human keying it into the system that’s the bottleneck.

Once I received the fob from our admin, I went to use it.  It didn’t work.  Damn.  I wondered if the office admin was vindictive enough to run a magnet across my fob.  Then I checked myself for thinking so highly of myself.  (Like she really cares enough to sabotage my fob!) I asked a maintenance man, who just happen to be passing by what I can do.  He asked me if I’m suppose to have access.  Did I pay for the fob?  Am I using someone else’s fob?  I was a little annoyed by the questions, but I kept a smile on my face and assured him that I’m suppose to have access.  He then directed me to the 3rd floor office of the building managers.

The lady in there was very cordial, and she told me that it’s possible I wasn’t pointing the fob correctly at the access point.  I knew that the fob should work, but I was willing to condescend her.  We walked down together.  She pointed the fob at the access panel, and sure enough, it didn’t work.  She told me that she didn’t understand; it should work.  Then, as if by magic, she remembered that they are working on the door; they are doing a software upgrade so the system may be down.  Obviously that wasn’t the case because there were people in the gym working out.  If the door was inaccessible, then they wouldn’t have been able to get in.  We went back up to her office.  She told me to call her in the afternoon, and she would attempt to re-add me to the system.  I told her okay, and I took a business card off here desk (she’s on the hook.).

In the afternoon, I called her, and she said that I was already in the system so my fob must be bad.  Come to her office and get another fob.  I get another fob from her, and she said that I’ll probably be good to go.  I told her that if it doesn’t work I’m coming back up stairs to see her.  I went down, and tried it.  No, it didn’t work.  So I marched back up stairs.  I’m very perturbed, but you have to keep on a good face.  She tells me that the software upgrade may have had trouble.  she’ll send one of the maintenance guys to give the fob to me once they get it working.  Later in the day, she calls me and tells me that the problem will be resolved early next week.

On Monday (today), my good friend, the office admin, came by and gave me the fob.  Hmm, I assume they got it working.  Being a tester, I got to go try it.  So I walk over to the workout facility and try it.  It doesn’t work.  I wanted to be mad, but I couldn’t bring myself to be angry.  It’s typical.  I thought they were going to try it before they sent it back over?  That’s what the lady promised.

Immediately, I go upstairs to the property management office.  Another lady greets me, and I tell her who I am.  She apologizes to me.  Apparently the other lady set me up wrong.  She explained that there’s two databases that needed to be updated with the information.  The first lady had just updated one.  Everything should be fine tomorrow once the system updates are in place.  The lady, to her credit, asked me if I wanted to use her fob to go workout.  I told her no; I just would like mine going eventually.  She told me that it should be fine tomorrow.  I told her that I didn’t believe her, but I will try it tomorrow.

WHAT’S THE POINT OF THIS WHOLE STORY?

I’m sick and tired of software excuses!  Don’t tell me the system takes a whole day to update!  I don’t give a crap that the system is down.  I don’t give a crap that two databases need to be updated.  It ought to just work!  As the user, I should be abstracted from all those details.  Here’s my user story: USER MUST BE ABLE TO USE KEY FOB TO OPEN THE DOOR.  Is that complicated?  Why can’t it be simple?  If it was just a regular lock, I  could have went down to Walmart, made a copy of the key, and got back in time to start achieving my fitness goals.  Why are there two databases that need to be updated?  It’s just one flipping door!  Software excuses are so ingrained in society that they are legitimate as “my diabetes is acting up”.  Nobody questions the bullshit of them.  And why is that?  I think it’s because most people don’t understand software.  As someone that understands software better than most of the populous, I say enough is enough.  I don’t care that systems are complex!  Stop the insanity!  This is a work in progress, but here’s my new software manifesto:

Daniel’s New Software Manifesto:

1) Software should be Simple to Use.  If your target user can’t *easily* use it (intuitive), it’s poorly designed, and it should chunked into the fire.

2) Software should Work.  Your software should work 99% of the time.  If your users are constantly complaining about problems with your software, then you suck and need to be chunked into the fire.  Don’t compromise on quality; it’s a slippery slope.  If you evangelize quality (and really mean it), you software will get better.

3) Software should be designed for the User.  I have an infinite amount of respect for Steve Jobs because he gets this.  He doesn’t have software developers (0r testers) designing the UI.  He actually pays people to design the UI so that Apple’s software looks slick and appealing.  I hate that companies are too cheap to invest in a good designer or user experience expert.  Design for the user!

4) Software downtime is Unacceptable.  Downtime is unacceptable for your software.  Make sure it’s up and running.  Regular maintenance is okay, but it’s not great.  The more you make this acceptable; the more downtime you’ll have.  Start with the premise that it’s unacceptable, and you’ll do better with it.

5) Software should fulfill the User’s Need. If you have software to control the access of a door, it better do it’s job.  If it doesn’t let the user in, it’s a utter failure and should be chunked into the fire.

EPILOGUE:

Probably when (if) they resolve my access issue, there will probably be no retrospective to say that things need to be different.  I sure the ladies in that office might feel bad for me, but nothing is going to change in their process.  I’m sure the second lady just thinks that it was a training issue with the first lady (i.e. if she knew that you have to do this and this and update two databases then that would have solved it).  But I really think that’s a wrong way of looking at it.  Maybe the software needs to be simplified.  Maybe they need some quality control in place (i.e. try the fobs on the door before they hand them off).  Maybe they need to restructure access systems.

But here’s the real food for thought: how many times do we as software professionals put the users through Hell and then not care?  I want you to empathize.  Every time you throw out some bullshit code, you are ruining someone’s life.  Do you really want to be the deliverer of misery in the world?  Do you want to blame their woes on your diabetes acting up?  Or do you want to say, “There’s no excuse.  Our servers sucks!  This code sucks!  This system sucks!  It’s imperative that we make it better.  To bring about a better world.”

As of today, I am officially a contributor to FitNesse. I contributed a new feature idea and its implementation (the initial idea was borrowed from FitLibrary’s SequenceFixture but morphed a bit based on suggestions from Bob Martin), and also worked on Slim version detection. I am not a developer by training nor trade, but armed with basic coding skills and fueled by the guidance and what I can only describe as the graciousness of Uncle Bob, I was successful. The experience was trying, exciting, and actually pretty fun. While I learned an awful lot more than I’m going to detail here, I think I had three really important realizations while working on the updates.

TDD Works!

Given that I am a tester, I have read/learned about, discussed, and even advocated TDD. Given that I do not (usually) write production code, I had never actually tried it. I decided I’d give it a go since I needed to write unit tests for my updates anyway.

The existing unit tests for the class I updated served as my guide. I wrote a test to verify the simplest case of the new feature. I ran it – here’s the interesting thing: it passed. This surprised me, but also informed me that I did not need to make any changes to the code for the simplest case. The update involved implementing a special character to invoke a different processing scheme for function calls in Slim Script tables, so I had figured that I’d at least need to update the code to ignore the special character in the simplest case…but as the unit test proved, I did not.

I wrote a second unit test to verify another simple (yet different) case – this one failed as expected. I added code to the class in question, ran the test, and saw it fail again. But aha – I also saw why it failed, and that information helped me find my mistake. At this point I’d like to say that I made the fix, ran the test, and saw it pass – but it didn’t happen that way. I went through a few iterations of running the test and fixing my code.

The test finally passed, and I ran the entire suite of tests for the class. They all passed. The most appropriate word I can find to describe that moment is epiphanic. It was then that I truly understood and appreciated two of the benefits of TDD I have often heard:

1. Practicing TDD can help ensure that only necessary code is implemented, since the goal of writing/updating the code is to make one test pass. Remember, I didn’t even need to write any code to make the first test pass.
2. Having a suite of unit tests – a byproduct of practicing TDD – can provide confidence that updates have not unintentionally changed existing behavior. The bonus is that unit tests are fast, so the feedback can be almost instantaneous. For example, the entire suite of 208 unit tests for the class I updated runs in under 1.5 seconds on my machine.

Having an understanding of a practice is one thing; having experience implementing the practice is another. Upon reflection, I now find it odd that I could have advocated TDD without having tried it myself.

Refactoring is more than just “Changing”

I’m a bit embarrassed to admit this, but up until recently, I used the word “refactoring” as a substitute for “changing,” since I thought that’s what refactoring meant. I thought it was just a dev-ified word for “changing” or “improving.”

Once I submitted the first update to Bob Martin, I asked him for feedback. I was quite proud that the new feature took only about a dozen new and updated lines of code, but I wondered what I could have done better. Uncle Bob told me that since I had added a couple lines of code to an existing function, the function’s length was getting to the point where he’d want to extract some of the functionality – he suggested extracting a particular loop to a “method object.” I immediately Googled “extract to method object” and found information about it on refactoring.com. I quickly realized that refactoring actually encompasses specific techniques that address specific scenarios – refactoring is not just changing code.

I’m not as embarrassed to admit that I really had no clue how to execute “extract to method object.” I ruminated about it for a few days, and finally just told Uncle Bob that I didn’t know how to get started. He sent me the code, explained step-by-step how he got to the end result, but still allowed me to commit the change myself…which leads me to my last point.

I think I know one reason why he’s called “Uncle” Bob

There were many times throughout the last few weeks that I wondered when Uncle Bob would say to me “I’ll just do it myself – it’ll be faster that way.” That certainly would have been a true statement. Being that I am not – as I stated before – a developer by training or trade, I was surprised that he even supported the idea of me actually committing code changes when I first contacted him to suggest the new feature. It turns out that my fear and surprise were completely unfounded. Uncle Bob continually offered guidance and encouragement, and always ended his messages with “Let me know if you need any help.” Here’s the kicker: he meant it, too.

I really did feel like I was the lucky recipient of mentoring by a person who has literally “written the book” (multiple books, actually) about software craftsmanship.

I hope that some FitNesse users find the new feature valuable, and that I will be able to contribute to FitNesse again in the future. It was a great experience.

In some companies, software testing is often used to combat bad practices.  Our code is crap and it’s breaking at every turn, maybe we need some people to test it so we can find the problems.  As awesome as testers are, we can’t save you from your bad decisions.  Do not be deceived!  You reap what you sow.

I believe in quality assurance (making sure the process is sound) more than quality control (making sure the product is sound).  If you’re doing things the right way, you have a great chance of success.  Part of the reason I believe in QA over QC is because of Sun Tzu.  In the Art of War, he  says, “Victorious warriors win first and then go to war, while defeated warriors go to war first and then seek to win.”  If you have a good process in place, then you can develop software with confidence that it’s going to be of good quality.  If you have no process or a bad process in place, you’re fighting for quality but only after the bad quality software is complete.

So, what are some things that might make a good software development process:

Code Reviews: One of the biggest things I learned at Edfinancial was the magic of code reviews.  They work on so many levels.  They work:

1. As a device to Share Knowledge among your team.  Are you in a company that has legions of siloed developers working on their own thing?  Put a stop to it!  Implement code reviews.  It forces your team members to see what each other are doing.
2. As a Learning Opportunity.  You want to know how to mentor your young coders?  Have them do code reviews with more experienced coders.  They will learn so much about best practices.  (Personally, I learned a ton from my former colleague Ryan when he did my code reviews.)
3. To Spur Collaboration.  When you have code reviews, this is a great time for spirited debate on the implementation of something.  Also, it prevents someone from completely going off the reservation.  It’s the reality check.  It’s the “What were you smoking?” check.  Many times crazy bad code just gets committed without so much as a once over.  That’s tragic!  Unacceptable!  And easily avoided!
4. To Find Bugs. Besides testers, you know who’s good at finding bugs?  Other developers.  They are great at it!  They are almost always tough on other people’s code, and that’s great for quality.  They will catch the honest mistakes.  Developers often catch their own mistakes as they are showing the code to someone else.  THIS IS BIG!!

Configuration Management: Systems are very complex.  So is code.  So is coordinating several people working on the same code.  You need to make sure that someone is keeping it all straight and enforcing the rules with an iron fist.  You want a process that’s well defined and repeatable.

1. Source Control: You should have all your production code in source control.  If you’re deploying stuff that’s not in source control, SHAME ON YOU!  You source is the life blood of your team.  Without it; you’re dead!
2. Automated Build and Deployment: Nobody should be doing the build and deployment of complex systems completely by hand.  People are too prone to simple errors.  There are countless tools out there that simplify this process.  For shops that do this manually, it’s a gut wrenching experience, but it should actually be as easy as pressing a button.
3. Change Control, Configuration: When you deploy code, do you know exactly what’s going out?  Can you easily tell me what’s been deployed, built, and configured?  If not, then why not?  If you have source control and automated build and deployments, then the change control stuff should be easy.  There ought to be logs documenting that.
4. No Hot Fixes on Production: You should not be making hot fixes on production!  That’s a sign of bigger problems.  And if you do have to make a fix on production it needs to go through a review and approval process.  And it should be the exception, not the rule.  It should never be some lone coder firing new code into production without consulting anyone.  That’s just plain stupid.

Priorities: What the heck are we doing?

1. Requirements: Testers can’t effectively test when there’s no expectation of what the code is suppose to do.  How are we suppose to verify and validate requirements when there are no requirements to look to?  The better question might be how do developers code without requirements?  Companies need to take the time to gather enough requirements to move forward with development.  NO!  YOU’RE NOT BEING AGILE BY HAVING NO REQUIREMENTS OR DIRECTION!  THAT’S CALLED AD HOC CHAOS.
2. Vision: Okay, requirements are a day-to-day thing, but what is the big picture?  What are we trying to accomplish long term?  Note that the less defined the vision is, the less chance that you’ll accomplish something specific.  Oh, and share the vision with the team.  Don’t make it a mystery.
3. Focus: Once you as a company has decided what the development team will work on, don’t constantly change your mind.  A whimsical manager with a big stick can kill productivity more than anything.  One completed piece of software is greater than 10 incomplete pieces.  Keep your eyes on the vision.
4. Realistic Expectations: Some managers think that they can complete software by sheer will.  If I crack the whip hard enough, the developers and testers will work faster.  If the team says 100 hours of development and 100 hours of testing, you as a manager can’t say I need that next Friday.  Sure you delivered it by some arbitrary date, but you will be putting fixes out for the next 6 months.

My assertion is that companies often attack the cosmetic, top level problems instead of attacking the root cause problems.  Testing is often a band aid thrown on the gushing wound.  If they were interested in fixing things, they would attack the root.

I think the big problem is that I am naive.  I assume that companies are indeed interested in fixing those quality issues.  But in truth, they are probably not that interested.  As a top level person in management, it’s more important that I get the product out than it being good quality.  It’s better to sell vaporware than to have a good product and not be able to sell it.  Rather than fix problems, it’s easier to look like you’re fixing problems.  We have quality problems so I hired some testers.  See!  I did what I’m suppose to do.  I didn’t give them power to effect the process, but it’s a nice gesture to have a token tester or two so they can say things like, “That’s whack!”

As long as the money is coming in, does quality really matter anyway?

*Gemba: A Japanese term that’s used in Lean to describe the source of the problem.  Literally translated, it’s “the real place” or “the actual place”.  In the context of manufacturing, it’s the plant manager going down to the assembly line to look at the problems.  I used that particular buzz word because I knew that it would make Bill happy.  Inside joke between us.

Aromas

It actually starts with the very first job I ever held – a barista position at the Aromas coffeehouse on the USD campus. My aunt, who worked at the university, told me about the coffeehouse and put me in contact with the manager. I interviewed over the phone, was hired, and found out when to report for my first day on the job. Of course, I called my aunt and thanked her for the introduction. Realizing I had not asked what it is I should wear my first day, I asked my aunt. “Oh, why don’t you wear a nice dress?” she replied.

I showed up to work in a lovely frock, and the very kind manager complimented me on my dress. The sarcastic assistant manager, however, pulled a “get a load of this gal” move with the thumb-pointing and everything. I wasn’t able to train that day because people learning to use an espresso machine ought not to wear short dresses and risk spilling 200-degree espresso on themselves.

Lesson Learned: Ask about dress code if unsure

First Testing Job

Fast forward 4 years – I was an eager young woman fresh out of college, ready to start making some dough to pay off my student loan. I got my first full-time job at Pacific Life Insurance Company as a QA Analyst. After the introductions throughout the cube farm, my boss sat down with me in my cubicle and handed me a CD so that I could install the product I’d be testing. I took the CD and just sort of stared at my computer for a few seconds…I extended my hand out to the thingy under the monitor that had a lot of buttons on it but could not figure out how to open the dang CD drive. My boss said very slowly “Um…the CPU is under your desk.” Forehead smack! I wonder if my boss freaked out just a tiny bit in that moment after realizing that the person he hired to be a tester couldn’t “work the computer.” Now, of course I could work the computer…thanks to my grandpa, I’d been using one since I was about 7…I was just really nervous!

Lesson Learned: Sometimes you just gotta laugh at yourself

First Agile Testing Job

OK, fast forward another few years. I had over 6 years of software testing experience under my belt and was interviewing for a tester position at Edfinancial Services. My potential future boss asked me for my thoughts on bug documentation. I said very confidently, “I document EVERYTHING.”  The rest of the interview went well, and I got the job.

My first day, my new boss sat down with me for a discussion about testing in an agile environment. We got to talking about bug tracking and he said, “I think tracking bugs found during the sprint is a big waste of time.” My mind immediately zipped back to my proud statement about documenting EVERYTHING. Oops…

Lesson Learned: Be prepared to change the way you’ve “always” done things!

My New Job

And now we’re pretty much all caught up…well, wait a second – I did start a new job yesterday. I’m now a software tester for a small group, and I am stoked to be working with Chris McMahon in this gig. Anyway, Chris and I were going through tutorials about the online app we’ll be testing. One of the tutorials provided a link to a “sample” workspace. I started playing around in the sample workspace and had some questions…I posted my questions on the wiki. Chris, our trainer Marcus (he’s a project manager/developer), and I started chatting about the sample space and Marcus asked me for the URL of the sample space. I barely got the sub-domain out of my mouth and Marcus exclaimed “That’s production!”

Turns out that the tutorials need to be updated.

Lesson Learned*: Some day, you WILL accidentally do something on production

*Actually, this was a reminder for me – I’ve already learned the lesson about messing around with production…brought a DB server completely down unknowingly once.

Well, there we have it. The pattern was not broken. The good news is that I really, really like the group of people I’m working with now, and hopefully won’t have to experience another first day on the job for a long while.

It was an excellent open space format conference.  Naresh Jain and Andrew Chen are great men to organize such an enlightening conference.  Also, thank you sponsors (Univ of Pittsburgh, Agile Alliance, Version One, Pillar, Open Information Foundation, Lean Dog, Foreopen, and Westinghouse.) for enabling us to attend the conference for free.  You guys rock!

To get into the conference, you had to write a position paper on a topic you’re interested in discussing.  My position paper was on “Do we, as software testers, really matter?”  You can go read it if you want, but it’s one of the most depressing pieces I have ever written so you’ve been warned.  Basically, the premise of the paper is does it make sense to have software testers anymore or is it a deprecated trade with the evolution of software development?  When I talk about the evolution of software development, I’m talking about things like Test-Driven Development (TDD).  Since developers are being to take a test first, proactive stance toward quality, are we as pure software testers still needed?

Roles?  Where we’re going we don’t need roles:

One of the guys brought forth the position that “roles are evil”.  Basically, his position was something like roles within a software team are damaging because it silos responsibility to one person.  For example, if something breaks in production, then the tester is at fault for not testing that particular part.  There were several people that agreed that the team should take responsibility for all aspects of the development of the software.  Instead of concrete roles, teams should have “specializing generalists”.  What that means is that you should hire exceptional people that are talented enough to fill many roles (writing code, testing, talking to the business, architecture) but maybe specialize in one or two things.  I call this the “Commando Concept”.  In commando teams, you might have a medic, a demolition expert, a linguist, a martial arts expert, but they are all commandos.  Everyone should have should general knowledge in each area.  If a man gets hurt, everyone on the team should be able to give him medical help.  If they need to take down a bridge, everyone should be able to set up the charges and blow up the bridge.  Of course, they all need to know how to handle a hand-to-hand combat situation.  In the same way, software team members need to be able to cover all roles in order to get things done.  I liked the concept.  I thought it was great.

Reality:

All of this sounds good, but in reality, it never works that way.  One woman named Audrey brought up the fact that when everyone is responsible for an item, no one is responsible.  Things that no one wants to do just fall through the cracks and don’t get done.  For instance, there’s many developers out there that really hate testing (I was surprised to find so many developers that love testing at the SDT Conference).  Some loath testing because they could be writing more code instead of testing.  So, instead of testing the code that needs to be  tested, they might take another coding task, and the testing never gets done.  Maybe it’s touch points with the business, where nobody wants to go talk to the business to hear about their technical pain points.  Roles are in place to make sure that someone takes up the responsibility for what needs to be done.  The tester position is in place so that someone on the team worries about quality control and quality assurance.  Testers think differently, and it takes a little time to switch between a developer hat and a tester hat.  Sure developers can write unit tests and check basic logic and functionality, but who’s going to find the strange bugs that can only be found through exploratory testing?  (And yes, these bugs exist.)  Can you find people that have the talent to fulfill all the roles and have enough motivation to do them well?  Even if you have exceptional people that can be a tester, a developer, a business person, and a user, can you get enough of them to fill a whole team?  In reality, most businesses can’t afford to retain that many exceptional people.  It comes down to pure economics.  For a business, it’s cheaper to have one rock star that can do anything and the rest of the people functional in their one role.  If you have a team of rock stars, then the company will break up that team and put one rock star on every team.  Or those exceptional people will leave the company in search of better opportunities.  Or worse, the company sees their greatness and makes them into a manager, giving them a raise and throwing all their talent to the curb to be eaten by rats, birds, squirrels, ants, and raccoons.

Conclusion:

There may be enough exceptional people out there that can form a team, take on all roles, but trust me, the company will be unwilling to pay for those people.  Even if they get them, they won’t be able to keep them.  Since we may not be able to get the pure, roleless team, let’s look at what we can do.  I think that you assemble teams, and you give them the expectation that everyone is responsible for everything, especially quality.  To borrow from the band U2, I’ll call this the “One“ Philosophy.  ”When it’s one need…We have to carry each other.”   As a team you have ONE goal: release high quality software.  It’s not your part and my part.  It’s the summation of all our parts.  It’s all or nothing!  One!  We have help each other out and fight through our collective short comings.  ”We’re one but we’re not the same…We have to carry each other.”  Your role is developer.  My role is tester.  We are not in the same role, but regardless we have to carry each other to reach our goal: release high quality software.  As you embrace this philosophy of One, you will see the roles become fuzzy.  A developer might do testing.  A tester might gather additional requirements.  And a business analyst might fix the code.  OKAY, THE LAST ONE MIGHT BE A STRETCH!  But the point is once you carry (care) for each other, those roles won’t matter.  One will matter.
