Investigating flaky tests is a dull necessity of testing. At least it is (in the best case) infrequent. Here are some shell commands you can use to automate steps in your investigations. These will work on (at least) bash and zsh.
At the start of March I started writing a blog post called “How to Speed Up Your Django Tests”. Before I knew it, the outline alone was 4,000 words! I realized writing it up would be a major undertaking. As lockdown arrived, I found the time to write it all up.
I occasionally enjoy solving algorithmic problems, for example Project Euler or The Advent of Code. I’ve been doing them since I was a pimply PHP-slinging teenager, competing with my peers across the UK in the British Informatics Olympiad. It was terribly nerdy and terribly fun.
My plugin pytest-randomly was recently moved into the pytest-dev organization on GitHub, making it a bit “more official” as a pytest plugin. Thanks to Bruno Oliveira for suggesting it, Florian Bruhin and Bruno for approving it on the pytest-dev mailing list, and Gordon Wrigley for helping with its development.
During PyCon UK I had the opportunity to work on open-sourcing our in-house Django performance testing tool, which has now been released as django-perf-rec. We created it over two years ago, and have been using and improving it since. It has been helping us to pre-emptively fix performance problems in our code, and now it can help you!
