How do I configure PyCharm to run py.test tests?

Question

I want to start writing unit tests for my Python code, and the py.test framework sounds like a better bet than Python\'s bundled unittest. So I added a \"tests\" directory t

Answer 1

It's poorly documented to be sure. Once you get add a new configuration from defaults, you will be in the realm of running the "/Applications/PyCharm CE.app/Contents/helpers/pycharm/pytestrunner.py" script. It's not documented and has its own ideas of command line arguments.

You can:

1. Try to play around, reverse the script, and see if you can somehow get py.test to accept arguments. It might work; it didn't in the first half hour for me.
2. Just run "py.test *.py" from a console.

Oddly, you will find it hard to find any discussion as JetBrains does a good job of bombing Google algorithms with its own pages.

Answer 2

PyCharm 2017.3

1. Preference -> Tools -> Python integrated Tools - Choose py.test as Default test runner.
2. If you use Django Preference -> Languages&Frameworks -> Django - Set tick on Do not use Django Test runner
3. Clear all previously existing test configurations from Run/Debug configuration, otherwise tests will be run with those older configurations.
4. To set some default additional arguments update py.test default configuration. Run/Debug Configuration -> Defaults -> Python tests -> py.test -> Additional Arguments

With 2018.3 it appears to automatically detect that I'm using pytest, which is nice, but it still doesn't allow running from the top level of the project. I had to run pytest for each tests directory individually.

However, I found that I could choose one of the configurations and manually edit it to run at the root of the project and that this worked. I have to manually choose it in the Configurations drop-down - can't right click on the root folder in the Project pane. But at least it allows me to run all tests at once.

I think you need to use the Run/Debug Configuration item on the toolbar. Click it and 'Edit Configurations' (or alternatively use the menu item Run->Edit Configurations). In the 'Defaults' section in the left pane there is a 'py.test' item which I think is what you want.

I also found that the manual didn't match up to the UI for this. Hope I've understood the problem correctly and that helps.
