Let's avoid hasattr hacks, just declare the required attributes on __init__. 👍

_syspath_prepended only stores the latest path called by syspathinsert, but syspathinsert might be called multiple times, and all paths should be considered.

Let's just store Path objects here, no need to store strings -- we can convert to strings later.

We should add all paths from _prepended_syspaths at this point.

Why are we setting sys.path and configuring PYTHONPATH? Isn't sufficient to only configure PYTHONPATH?

Actually I don't think we need to modify runpytest_subprocess at all, given we are already configuring PYTHONPATH in popen?

Thanks @Oreldm for the contribution, please take a look at my comments. |
