Bug 832168 – emerge behavior with --onlydeps --with-test-deps --usebinpkg is nonsensical

• Status: CONFIRMED
• Product: Portage Development

I often want to install test deps of a package without installing the package itself. E.g.:

# emerge app-shells/autojump -va1 --onlydeps --with-test-deps --usepkg

If no binary package for autojump exists, then things proceed as expected:

> These are the packages that would be merged, in order:
> 
> Calculating dependencies... done!
> [binary  N     ] dev-python/cfgv-3.3.1-1::gentoo  USE="-test" PYTHON_TARGETS="python3_9 -python3_8 -python3_10" 0 KiB
> [binary  N     ] dev-python/nodeenv-1.6.0-1::gentoo  PYTHON_TARGETS="python3_9 -python3_8 -python3_10" 0 KiB
> [binary  N     ] dev-python/ukkonen-1.0.1-1::gentoo  USE="-test" PYTHON_TARGETS="python3_9 (-pypy3) -python3_8 -python3_10" 0 KiB
> [binary  N     ] dev-python/identify-2.4.0-1::gentoo  USE="-test" PYTHON_TARGETS="python3_9 -python3_8 -python3_10" 0 KiB
> [binary  N     ] dev-vcs/pre-commit-2.15.0-1::gentoo  USE="-test" PYTHON_SINGLE_TARGET="python3_9 -python3_8 -python3_10" 0 KiB

But if a binary package for autojump exists, emerge decides that it doesn't need to do anything!

> These are the packages that would be merged, in order:
> 
> Calculating dependencies... done!
> 
> Total: 0 packages, Size of downloads: 0 KiB
> 
> Nothing to merge; quitting.

regardless of whether the test dependencies are installed.

emerge should install the test dependencies, independent of whether a binary package for autojump exists.
