My first pair testing session – Day 21 of 30 Days of Testing

PAIR TEST WITH SOMEONE

Some time ago I’ve read a great article by Katrina the Tester on Pair Testing. This topic since then would often pop up, but I never had a chance to actually try it out.

I am very grateful and lucky because I have super supportive colleagues when it comes to 30 days of testing challenge. Not only that they show a sincere interest and ask about the progress, but they also agree to get involved into some of the challenges. At the very start of July, I was talking to one of our great front-end developers and mentioned pair testing as one of the challenges. He immediately said “I can do it with you!”.

Ironically, today I did not have any specific task which we could pair test, so we thought of testing an existing feature.

In the very start it was a lot about seeing how he does testing. It is fairly different than my testing, so it was very beneficial to me. He showed how he configured dev environment locally for testing so he could fix any coming up issues as well immediately.

Then, we tried to specify on how this feature should be tested. This involved some UI tests verifying requirements, but not only that – we looked at monitoring, requests being sent. Usually, when I test, I concentrate on UI when the feature is mainly seen on the UI, but it was great to see how differently the very same feature is viewed by a developer who knows what events are being recorded and which requests should be sent for the feature to work. He as well showed me some of his unit tests for that feature.

To sum up, we asked when we can say that we have tested the feature completely. How much is enough? What should we do to be sure that it’s well tested?

This question is a challenging one. We decided that in addition to what we discussed, we should as well just try to be users for a while and try to use the product. Funny enough, trying a few of scenarios – we found a bug. In a tested released feature in production.

Here came in a very important point in testing: while testing one of the features you can have blind spots on some of inconsistencies on other existing features, so it’s best to stay alert and check for regressions which concentrate not only on the new feature.

Pair testing definitely exceeded all my expectations: I learned a lot new ways how to test, and, seeing the product with the help of different set of eyes even helped us to find a bug!

And, it was all about improvisation and sharing knowledge rather than dictating the rules.
