how are you setting up excellent testing? using AI agents? hand writing tests? I hate talking to AI, I wish I could just write the test and the AI agent implement the fix

I am hand-holding the AI on the e2e setup. It mostly consists of Playwright + Cucumber + a test API to set up more complex scenarios. I also have unit tests for logic that lends itself to that. I also use mocked LLM responses for LLM projects.

If you enjoy writing tests, AI is really good at finding appropriate fixes for bugs that are easily reproducable. Just make sure to always have another AI review the fix. Otherwise you get a lot very, very dirty quickfixes. (At least in my experience.)

Thanks for the reply! So you would say that you have personally reviewed all the tests?

I’ve been thinking about how tests comunícate product function much more clearly and durably than prose, and that it maybe possible to create some sort of portable testing SDK that connects to the codebase and allows the dev to talk to the AI by just carefully writing tests, posting them to a backlog for the AI to pick up and edit the codebase until green.
