Can we update these tests so that they test as much of the functionality end-to-end as possible? Almost everything is being patched here, which doesn't make these tests that useful. Our CI runs on both Linux and Windows so you should be able to at least test these systems end-to-end.

not sure if there's a better way for me to run this on windows but scope it to just this test suite?

[herin049]

You shouldn't need to touch these files at all, you should be able to just have pytest skip the platform specific tests if they don't match

[herin049]

Look at @pytest.mark.skipif or @unittest.skipIf

i am using something similar: https://github.com/open-telemetry/opentelemetry-python-contrib/pull/4843/changes#diff-d44fe2506f2682e80ab459c5ef5c010e9bef8f4ff0af3965d47be85c97e00595R58-R61

But i dont see any of the jobs using a windows image?

[jaydeluca]

if you'd prefer, i can remove all of this to keep it simple for now and followup with a change scoped to just introducing the change to run this on a windows runner. the windows specific tests just won't run for now
