A QA-guy blog

Intro I turn on my TV-set. I start my favourite TV application to watch a TV-show. It says there's a new version and insists on updating. Would I have access to new TV-shows or movies after this update? Not at all! Would this application work faster after that? Hardly. Would it be more stable? Hopefully, but no guarantees. What would this update give me? New UI (I was OK with the old one). Ability to choose which trailer I would like to watch (like I need more than one). It eats my internet traffic and time and gives me nothing of value in turn. I need to sort out my finances. I take my cell phone. I start an accounting application that works with my bank. It wouldn't start. Connectivity issue - it says. In reality - what I need is to go to Google Play and update the application. After the update, it looks slightly different, has some new feature I don't need and would hardly use and obfuscates previously learnt path to the features I need. The problem Both...

Some time ago I had an argument with another team member - he was claiming that Test-driven development (TDD) was not applicable to our application. He thought it would be more efficient to rely on manual or E2E testing instead. I disagreed. Without going too much into the details, the core of the application we were working on was a graph-traversing algorithm with some amount of mathematical calculations. It was painful to test on a system level as the number of possibilities was huge and it was not easy to put the system into a particular state to check specific conditions. I thought that thorough unit-test coverage, and, ideally, TDD would be more efficient, but was not able to persuade my colleague. At the end of the day, I started to doubt if I was right. Challenge was accepted, so I tried to do something more or less similar (though simplified) - implementing a Tic Tac Toe computer player logic via as pure TDD as possible. Long story short, after some time I managed to g...

I have published several posts with the aim to deliver one message - sometimes it is more efficient (fast and convenient) to change the application under test (make it more testable or eliminate the need for testing at all) then invent or employ complicated test automation techniques to check the same functionality. Even though there was a lot of misunderstanding caused by badly forming those posts, I still think I stroke something deeper. For instance, this twitter post made me think that we speak two different languages: That's like asking a pharma company to self-certify that their drugs are safe without any independent approval! #softwaretesting #CIO — Ayush Trivedi (@ayushtrivedi) 4 September 2017 Now it started to seem to me that there're two different views on what test automation is. First, probably prevailing point of view is that test automation is a part of ages-old traditional QA process, where test automation specialist is just a test specialist usin...

There's something that I haven't seen in the education plan of IT degrees ever - professional ethics, and I think it is a huge miss. Ethics is being taught for lawyers, MD, teachers and lots of other degrees. Ethics tells us that there's something beyond our job responsibilities. Ethics reminds us that the one who is footing the bill may not be the final decision maker of everything. That if something is legal, it yet does not mean it is a right thing to do. Let me share a story about one of my previous project. I was working for an IT services company and we were helping our client to deliver a new version of the software. A peculiar thing was that if there were a bug in the Product, then something horrible could happen (in the worst case - somebody could die). And I was the quality guy on a project. Our sponsor (the one, who was footing the bill, and ultimate decision maker) had his deadlines. He already made a demo for marketing people and wanted to ship the softwar...
