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

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.

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.

With a special Conda python setup which included the pip install for py.test plus usage of the Specs addin (option –spec) (for Rspec like nice test summary language), I had to do ;

1.Edit the default py.test to include option= –spec , which means use the plugin: https://github.com/pchomik/pytest-spec

2.Create new test configuration, using py.test. Change its python interpreter to use ~/anaconda/envs/ your choice of interpreters, eg py27 for my namings.

3.Delete the ‘unittests’ test configuration.

4.Now the default test config is py.test with my lovely Rspec style outputs. I love it! Thank you everyone!

p.s. Jetbrains’ doc on run/debug configs is here: https://www.jetbrains.com/help/pycharm/2016.1/run-debug-configuration-py-test.html?search=py.test

find this thread when I hit the same question and found the solution
pycharm version:2017.1.2
go to “Preferences” -> “Tools” -> “Python Integrated Tools” and set the default test runner from right side panel as py.test
solve my problem

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

I’m using 2018.2

I do Run -> Edit Configurations…
Then click the + in the upper left of the modal dialog.
Select “python tests” -> py.test
Then I give it a name like “All test with py.test”

I select Target: module name
and put in the module where my tests are (that is ‘tests’ for me) or the module where all my code is if my tests are mixed in with my code. This was tripping me up.

I set the Python interpreter.

I set the working directory to the project directory.

Here is how I made it work with pytest 3.7.2 (installed via pip) and pycharms 2017.3:

1. Go to edit configurations

2. Add a new run config and select py.test

3. In the run config details, you need to set target=python and the unnamed field below to tests. It looks like this is the name of your test folder. Not too sure tough. I also recommend the -s argument so that if you debug your tests, the console will behave properly. Without the argument pytest captures the output and makes the debug console buggy.

4. My tests folder looks like that. This is just below the root of my project (my_project/tests).

5. My foobar_test.py file: (no imports needed):

def test_foobar():
    print("hello pytest")
    assert True

6. Run it with the normal run command

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.

Enable Pytest for you project

1. Open the Settings/Preferences | Tools | Python Integrated Tools settings dialog as described in Choosing Your Testing Framework.
2. In the Default test runner field select pytest.
3. Click OK to save the settings.

In pycharm 2019.2, you can simply do this to run all tests:

1. Run > Edit Configurations > Add pytest
2. Set options as shown in following screenshot
   
3. Click on Debug (or run pytest using e.g. hotkeys Shift+Alt+F9)

For a higher integration of pytest into pycharm, see https://www.jetbrains.com/help/pycharm/pytest.html

Open preferences windows (Command key + "," on Mac):

1.Tools

2.Python Integrated Tools

3.Default test runner

There is a PyCharm documentation: Run/Debug Configuration: pytest available as of SEP 2020.

I came across with a bit another case but the same error
(I can’t past the error here cuz already fixed it).

Check that you really have pytest installed inside your venv.
I have pytest installed globally and it’s confused me.

If pip is saying that pytest is already installed – check what kind of pip it is (global pip or pip of venv).

which python should return the path to your venv python.
Then python -m pip install pytest

To me help next solution:

1. Go to settings of config
2. Add new config
3. Delete old configs
