test_gp_kernel error "fixture 'mocker' not found"

Running the tests for current main (508843d), I found this:

$ python -u -m pytest -k test_gp_kernel
[...]

This is my fault, I forgot to add pytest-mock package to the setup file. I can make a PR later today/tomorrow fixing this. To make the pytest work you only need to install pytest-mock via pip.

Thanks & no rush :) I was wondering why the CI didn't choke on that, but it installs pytest-mock, so it only shows when running tests locally. In the CI, you could do pip install -e ".[tests]" once pytest-mock is in setup.cfg.
