Interested in this as well! the ability to use an external test runner was recently added I still have to look at it

Afaik the poly team's recommendation is to keep quick tests with the bricks and put slow tests into projects but this might not fully map to Tommi's question

Thanks. Putting tests into projects is a good idea, but would still like to have a filter "run only when I asked to" as the tests can be flaky, and should not run by default, even if the project needs to change.

I haven't worked out how to forward command line args to kaocha, if you have ideas, a pr is welcome in polylith-kaocha

It feels like being able to turn on/off tests could be convenient regardless of which test runner you use. We should spend some time to figure out how to best support this.

Since test discovery is the responsibility of the test runners, I don't see how this could be handled outside of them

Or at least without their participation

We can exclude which bricks to test per project today in workspace.edn in the :test key for each project. I was thinking that we maybe could have some other test configuration as well to support this use case. Worth thinking about.

Certainly
