Enable copying test binaries to a canonical location

[iand675]

General summary/comments (optional)

I would like to be able to store builds of a project's test suites as artifacts for usage on other machines. While stack is able to do this for normal executables, there doesn't seem to be a supported way to do this for test binaries. I can of course dig around in the .stack-work directories for each project, but it's not ideal.

Steps to reproduce

Run stack build --fast --test --no-run-tests --local-bin-path check --copy-bins in a project with tests and look at the contents of the check directory. There will be no test bins for the local packages.

Expected

If --copy-bins doesn't provide the functionality, I'd hope for a separate flag to support easy access to test bins.

Actual

No test bins.

Stack version

$ stack --version
Version 1.9.3, Git revision 40cf7b37526b86d1676da82167ea8758a854953b (6211 commits) x86_64 hpack-0.31.1

Method of installation

• Official binary, downloaded from stackage.org or fpcomplete's package repository

Thanks @iand675 - even though there are existing workarounds this seems like it'd be a nice feature to have, and it makes sense given that you can already do this with regular binaries.

Any chance you'd like to submit a pull request to implement the behavior you're asking for above?

As it happens, we're in the midst of rolling out a new policy for feature requests:

@malteneuss it seems that the issue is about providing similar functionality to what currently --copy-bins is doing, the change is that if --test is present, then we should also copy the test executables? Do I understand this correctly?

@iand675 ^^ is the above comment correct assumption?

I think your interpretation is right @rabbitonweb.

I'm going to close based on the new policy I mentioned above since it's been more than 30 days and nobody has submitted a PR, but I'll add this idea as a feature request on our wishlist wiki.
