Use the execnet main_thread_only execmodel so that code which expects
to run in the main thread will just work. This execmodel has been
merged to the execnet master branch via pytest-dev/execnet#243, so this
patch should not be merged until there is a released version of execnet
supporting the main_thread_only execmodel.
Closes#620
- Use pytest>=6.2 features (same as install_requires).
When we can require >=7, can fix some more typing omissions and
version checks.
- Replace testdir with pytester
- Replace py.test with pytest
- Replace tmpdir with tmp_path
- Remove (almost) all other uses of py
- Add some type annotations (not checked yet)
Ref #722.
