--installpkg Ignores deps, intended and how to work around

[tapetersen]

Hello, I'm using tox for running tests in a project where I have a makefile that builds packages separately when making a release.
I would like to test those using tox without rebuilding them a second time but instead install from the already built package.

Using the --installpkg option seems intended for this usage but it adds the --no-deps flag to pip install which means its requirements aren't installed. I could of course add those to the tox.ini as well but I would rather keep that information in the setup.cfg only.

I can understand why you sometime would like to explicitly only install a and not its deps it would be useful if the alternative exists and would actually be the default I would've expected. Is there some way to get the desired behavior anyway either by telling tox to install dependencies from setup.cfg or installing from the built package including deps?

This improvement for --installpkg has been added to tox 4 via #2235. There are no plans currently to support this within tox 3.

Ok I'll try and see if tox4 works for us as we're not depending on any external plugins. Thanks for developing tox and taking time to help.
