Developers Developed by Tester Tested

I was testing a product last year in a capacity where the development team was just a floor away from me. Initially, I found so many crashes during the first few releases and there were crashes that I could find even after a couple of months and that's bad ( may not be too).

I take the credit of making those developers to do a better unit testing. I did not do that just by finding bugs but did a few things that I'd like to list for you:

1. Festivals and realizations:

One day, I went to the developers with a print out of heuristics and test data that I have been using to find crashes that made them sit and fix bugs, during festival season. It's painful to sit in office and work when the whole nation is celebrating. This psychologically affects them and in my opinion, developers need our help to enjoy festivals and weekends.

So by giving them my customized cheat sheet, I made them aware of those tests that have made them work during festivals. I did not say anything more than that during that meet. Some changes are set to happen by it self, all it needs is a trigger and I provided it.

Outcome:

1.a. Developers used my cheat sheet for unit testing.

1.b. I forced myself to think of more test ideas to find more important problems, quickly.

1.c. It became easy for me to ask the developers, "please send me your unit test results".

1.d. One of them told, "I am using this sheet because I want to enjoy my holidays and not that I want to do unit testing". Whatever is the reason, I am happy that they are doing!

1.e. The unit test results they produce, gave me new ideas.

2. Two to tango:

I frequently consulted other teams during "critical moments" ( as they call ) that they faced. I once had to pair with a developer for a testing activity.

It was a little gimmick that I played with him that got him thinking of doing unit testing better than before. All I did is to say, "Hey, you better close your eyes and don't see what I am doing. I would do some little tricks that testers usually do to find some important problems. If you are careful and observant, testers like me might not be able to find bugs in your code".

Outcome:

2.a. Had I continued without that gimmick, he might not have opened himself for a careful observation of the kind of tests that I did as any other developer to my knowledge doesn't carefully observe a tester at work.

2.b. He unit tested and then said to me one day, "Pradeep, you shouldn't have showed me the tricks. Now my testers are facing a tough time to look for those crashes that they usually find in my code". I just had a smile in my face. I was convinced that he didn't understand what was running in my mind but that's fine with me.

2.c. Maybe the testers of his team might have come out with more test ideas than to look for the same crash that they are accustomed to. Well, I admit I don't know about that but it's my guess.

3. Patterns and structure of crimes:

Sherlock Holmes, as many of you might know still lives in Bakers Street providing inspiration to testers like ( not a great tester ) me , Robert Sabourin (great tester) and many other great testers, observes patterns and structure of people whom he suspect to be criminals and tracks down the criminal based on the pattern and structure of crime.

I observe a pattern and structure through the bugs that arise from a developer's code. It has helped to build my intuition and hence when I get a release with changes made by a specific developer, I look for those patterns and structure, which has been handy sometimes to find important problems, rapidly.

I felt it's a good idea to inform the developer, my observation about the pattern and structure of the bugs that arises of his code and did it in a polite way ( developers aren't criminals, remember).

Outcome:

3.a. He said, "Thank you! I now know where to work on and develop my development skills."

3.b. Our relationship got stronger.

3.c. I am convinced that good testers can help developers to develop their development skills.
(For those developers looking at this post, I hope you got a reason why you should lend your hand when we want to shake hand with you, for your own benefit. We love shaking hands with anyone who could help us better our testing and you are important to us)

Meta cognition helps me develop my testing skills and testing activity and I am happy that it helped others too.
