Pycharm unable to run single parameterized test from selection.

Hello.

Running concrete parametrized instance is not supported for now. In next version we will improve and document API to make it user-accessible, but we only can implement it if py.test itself supports this scenario. Does it?

Hi Ilya Kazakevich,

Thank you for the reply.

Py.test does support executing one test case.

py.test "query_planner/test_ast.py::TestASTMeasuresNoGroupBy::()::test_ast_basic1[measures0-exp_measure_types0]"

for class TestASTMeasuresNoGroupBy:

    @pytest.mark.parametrize("measures, exp_measure_types",testdata)

    def test_ast_basic1(self, measures, exp_measure_types):

similar for 

@pytest.mark.parametrize("filter_id", list(range(12)))
def test_filter_basic1(self, filter_id):

py.test "query_planner/test_ast.py::TestASTSimpleFilters::()::test_filter_basic1[0]"

Let me know if I could help in any way.

Thanks!!

Hi Ilya Kazakevich

How it's going on the way to implement this issue ???

So 4 (four) years have passed since the question was posted !!!

REALLY annoying :(

Thinking to roll out to VS Code...

Hello Dharmagetic,

I believe this is already implemented for pytest. Could you please check?

Hello Ilya Kazakevich

Seems it's doesn't work

I'm running Pytest for single Django test as described in https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000491790-Using-Pytest-with-Django

This single test decorated with @parameterized.expand

WARNING !!!

This decorator exists in https://pypi.org/project/parameterized/ packed, but it is not originall pytest's fixture

And finally I'm getting:

ERROR: not found: "path/to/test"

Process finished with exit code 4

Empty suite

Can Pycharm support https://pypi.org/project/parameterized/ package ?

Hello.

This is a different probklem, unfortunately. Please, create an issue

https://youtrack.jetbrains.com/newIssue?project=PY

Hi JetBrains - any update on this - we have many a long running test where each parametrized test takes about 30 seconds - so waiting to go through 8 passing tests to get to the parametrized test that you want to test it a big bother.

And someone from my team just showed that VScode is able to do this - so it is definitely possible.

Can you give a time-frame on when you will fix this (rather basic) feature?

PyCharm does indeed have this feature but it seems to only work if your parameters do not contain dots (either float number or in string). I created a new bug report for it: https://youtrack.jetbrains.com/issue/PY-56894/Pycharm-unable-to-run-single-parameterized-pytest-test-from-selection-when-there-is-a-dot-in-parameter-value

Ahh - so that is why nobody else hit the bug - out patameters also contain dots.

Hit the same issue but I run unittests

https://youtrack.jetbrains.com/issue/PY-56683/Running-a-single-test-using-parameterized-decorator-within-PyCharm-fails-with-Empty-suite

If you add the main, it will be empty if you run a particular test.

```
    raise TypeError("don't know how to make test from: %s" % obj)
TypeError: don't know how to make test from: None
```
