Hyperspy 1.6.1 next_minor and next_patch branch Pytest failed with error: unrecognized arguments: -n --dist loadfile

kevinsmia1939 commented 4 years ago

Hello,

I was just testing upcoming 1.6.1 because I want to package it to openSUSE Tumbleweed. I am aware that 1.6.1 is not release but I just want to check that it came out smoothly. I build hyperspy 1.6.1 from the latest snapshot next_minor and next_patch branch. I found Pytest error as shown below.

This error both occurred on next_minor and next_patch branch.

[   83s] + pytest-3.8 --ignore=_build.python2 --ignore=_build.python3 --ignore=_build.pypy3 -v
[   84s] ERROR: usage: pytest-3.8 [options] [file_or_dir] [file_or_dir] [...]
[   84s] pytest-3.8: error: unrecognized arguments: -n --dist loadfile

Have this error been made aware of? If so I don't have anything to add.

I'm pretty sure this is because you are missing pytest-xdist, which @tjof2 introduced in #2520 for parallel execution of tests. I'm on mobile so I'm a bit slow in checking whether we've added the above to the dev package dependencies.

tjof2 commented 4 years ago

From the docs https://hyperspy.readthedocs.io/en/latest/dev_guide/testing.html#running-tests

First ensure pytest and its plugins are installed by:

# If using a standard hyperspy install $ pip install hyperspy[tests]

The dependencies are listed here: https://github.com/hyperspy/hyperspy/blob/912fc5776c0f8c604cb339332760b3cbd0058386/setup.py#L81

An ugly hack is to override the config in setup.cfg, e.g. pytest -c /dev/null hyperspy/ - so it looks elsewhere for the config. Would not recommend though.

Hello,

Thanks, the test is working now. I also noticed that test need matplotlib>=3.1 but install need matplotlib>=2.2.3. Is this a conflict?

Thank you.
