Hi,
For pytest-testmon plugin I need to extract all node ids which exist in a
python file (after parametrization). Initially, I thought
pytest_collection_modifyitems used as a hookwrapper would have all the
node_ids in all the files (which would be ideal for me). It turns out if
you call pytest test_a.py::test_1 , pytest_collection_modifyitems only gets
test_a.py::test_1 (but no other nodes which might be in test_a.py).
pytest_pycollect_makemodule sounds like the pretty low-level hook which
should get all I need. However, it gets a hierarchy, which I have to
manually flatten. My gen_nodeids bellow looks like a code that definitely
lives somewhere in pytest. What is the optimal and most forward-compatible
way to get the list, please? Below is what I came up with so far (and it
seems to work).
I would be glad to get any comments or pointers.
Best,
Tibor
