[pytest-dev] Not running standard pytest collector for file spec/*_spec.py

[Bruno Oliveira]

Hi Ringo,

It is as Ronny said, you can see the code responsible for that here:

https://github.com/pytest-dev/pytest/blob/master/_pytest/python.py#L162

When the file has a `.py` extension and is one of the "inipaths" (paths
given explicitly in the command line), then the `python` plugin will
collect that file anyway.

You can override this by implementing your own `pytest_collect_file` and
return non-`None` when a `.py` file inside the specs directory is passed in
the command-line.

Cheers,
Bruno.
