Listen "165 - Flaky Tests"
Episode Synopsis
Changelog
I’ve sorted the Kubernetes ingress controller for the staging deployment of howtocodewell.net
I’ve got a few problems with connecting services outside of the Kubernetes cluster but I am working my way through those.
I’ve been updating the pipelines to allow for certain manual jobs in GitLab.

I have my eye on the podcast 2.0 movement and may start to add some backlog tickets to investigate what is involved from a technical standpoint to updating the RSS feeds.

This could be a neat little future video tutorial. I could also do something similar with a Discord bot.

What’s a flaky test
A flaky test is a test that sometimes passes and sometimes fails. This usual happens randomly and is incredibly annoying.
What causes flaky tests
Under powered resources
Tests running in random order
Tests not cleaning themselves up afterwards
External programs or requests interfering with the tests
How to fix flaky tests
Run tests more regularly
Separate flaky tests and run them in isolation until fixed
Only test what is needed based on what has changed
Don’t ignore or skip tests if you can help it
Check the environment
Check inputs for non-deterministic values
Check timeouts
Check system resources
Check for race conditions
Check if there is any fixed order to the tests
Keep your tests maintained.
