How to nest markers inside a parent marker?

[FeryET]

Hi.

I'm trying to come up with a solution to have more finegrained marking for my tests.

import pytest

@pytest.mark.sub.pass
def test_pass():
    pass

@pytest.mark.sub.fail
def test_fail():
    raise Exception()

I want to have a parent maker like sub above that has multiple submarkers. Is this possible using pytest?

Currently markers don't have that feature

Without a compelling concrete use cases I'm not convinced of that feature

Note you could DIY a thing like this as well:

import pytest

class MarkerGen:

    def __init__(self, parts=None):
        self.parts = parts or []

    def __getattr__(self, name):
        return MarkerGen(self.parts + [name])

    def __call__(self, *args, **kwargs):
        path = ".".join(self.parts)
        marker = getattr(pytest.mark, path)
        return marker(*args, **kwargs)


mark = MarkerGen()

@mark.sub.passing
def test_pass():
    pass

@mark.sub.failing
def test_fail():
    raise Exception()

Using . as a separator might be a bit unorthodox, but works thanks to getattr(), so you can select the two tests with -m sub.passing and -m sub.failing respectively.
