Since bug 1464082 we have pytest vendored in tree now, but for a variety of tests it would be great if we could also switch from the mock package to pytest-mock.

Vendoring the required packages will be done via:

$ ./mach vendor python pytest-mock==1.10.1

Running this locally I can see dependencies on mock, and pbr.

Andrew, I stumbled over this 3 years old bug and wonder how our strategy is nowadays. I cannot see pytest anymore under the Python vendored packages. We still have mozbase packages that use pytest for their unit tests. So where is pytest coming from?

Further I don't have a usecase for pytest-mock right now given that I haven't worked on mozbase for quite some time, but maybe it would still be helpful to have?

The dependency on pytest is now defined here, we don't need to vendor it anymore (🎉).
If we added pytest-mock, I'd recommend adding it to that file.

I'll personally give you a 🤷 on pytest-mock over the builtin unittest.mock module, but I trust the judgement of you two :)

Yeah, I don't have any opinions or knowledge on what pytest-mock offers over the built-in one. So if you want to use it I'd say go ahead and add it (via pypi not via vendor).

Given that there is no need for me right now I'm going to close as incomplete.
