Both this article and this comment thread include a number of different ideas regarding controlling (or randomizing) environmental factors: test ordering, system time, etc. But why do all of this piecemeal? Our philosophy is to create a controlled test sandbox environment that makes all these aspects (including concurrency) reproducible: https://www.cloudseal.io/blog/2018-04-06-intro-to-fixing-flaky-tests https://www.cloudseal.io/blog/2018-04-06-intro-to-fixing-fla... The idea is to guarantee that any flake is easy to reproduce. If people have objections to that approach, we'd love to hear them. Conversely, if you would be willing to test out our early prototype, get in touch.
