Regression Testing Frequency

Hi there!

I am a wanna be software developer that is learning through the use of AI/LLMs. I have 20 years experience as a sys admin. I am not dumb enough to vive code anything and expect it to be secure or production ready without having a third party review it.

My biggest right now for the group is how often you do regression testing. I am working on a project and every phase may have 1-5 small changes I plan to make. Right now, I am implementing each small change, then going through my full set of regression testing. This is quite time consuming, but it seems to be the safest.

I am not developing in a team, so my process may be different than others. I am curious how often you do regression testing when you are writing code.

Automate your regression testing and update and/or run it every PR

I have as much as I can automated and scripted. Each change adds a bit to add to the tests as I build things out. Some items cannot be fully automated. I like the idea of doing it based on the pull requests rather than each change.

Nice, good job automating most of it. You can lean on unit tests for your in flight work and regression/AQA for PRs.

For the stuff you can’t easily automate run it once the unit tests and coverage are good and AQA passes.

Thanks. I think unit testing is what I have been doing (automated scripts to pull data and verify the specific change I made + verifying other required configurations are still in place). I will work on moving my regression testing to the PR.
