Is there an undocumented

--dry-run

or something similar in Pants? I want to integrate it into my CI process, and want to run some quick checks on my local machine first to verify that

--changed-since

will work as I expect upstream. E.g. "Show which tests _would have ran_`.

Maybe I do not understand you correctly, but you can just run your pants command with

--changed-since

locally?

Morten, can you

pants list

instead with filter to see which tests will get run?

Copy code

pants --changed-since=main list --filter-target-type=python_test

The output from here should be the tests that will get run if you replace the

test

with

list

That should do it, @late-advantage-75311, thanks!

I could do that @lemon-yak-80782, but that would actually run the tests as well, I was looking for an overview of which files would run and easily compare them when making changes.

Morten, btw, are you sure that changed-since is what you want? for the case of tests

oh sorry, my bad,

--changed-dependents=transitive

is a separate flag
