Prevent --file-watch from watching test suites

[JoeMShanahan]

How appropriate would it be to allow a new argument which prevents stack from triggering a rebuild when a test suite changes?

During development of a web app using yesod, we're in the situation where I'm running the server with yesod devel (which uses stack ... --file-watch underneath).

Our selenium test suite is attached to the server devel is running. I'm altering some selenium tests which I have loaded with GHCi. When I change the selenium tests, stack notices, which signals to devel that a rebuild is required even though it's not! This really just slows down development.

I propose something like stack build --file-watch --no-watch-tests . What do you think?

It may even be reasonable to have that behavior automatically implied based on which components are being built. I don't see a downside to such a change.

I was about to log an issue for this but looking at the linked issue it seems to be fixed in 1.6.

I've updated and just tested on my setup and I'm not seeing changes to the tests retriggering builds when they shouldn't now. Woohoo!

Can probably be closed as fixed now?

Nice one!

Cheers
