Apply custom markers to specific value of pytest parameterized marker

Question

import pytest

@pytest.mark.parametrize('a', [0, 1])
def test_increment(a):
    pass    

I want to apply custom-marker to a specific value of a marker. In the above-mentioned test case to be should be executed with

• a=0 if -m one is provided.
• a=1 if -m two is provided.

I tried the following snippet, but it doesn't work.

import pytest

@pytest.mark.parametrize('a', [pytest.mark.one(0), pytest.mark.two(1)])
def test_increment(a):
    pass    

Answer 1

I was able to provide custom marker to a parametrized test using pytest.param.

Snippet

@pytest.mark.parametrize('a', [pytest.param(0, marks=pytest.mark.one), pytest.param(1, marks=pytest.mark.two)])
def test_increment(a):
    pass
