mapping the fixture parameter with the test method parameter

[markshao]

I have the test cases to test some sftp related features under different OS . For example test the file path existence under both windows and Linux.

The test function support two kind of parameters , first parameter is the fixture returns a paramiko ssh connection , the second parameter is a normal string parameter for the file path.

import pytest

@pytest.fixture(scope="module", params=("linux", "windows"))
def ssh_connection(request):
    pass


class TestSftpUtil(object):
    @pytest.mark.parametrize("path", [("c:/windows",), ("/root/path",)])
    def test_is_file(self, ssh_connection, path):
        assert True

Now the pytest traverse all the possible parameter groups

test/test_sftputil.py::TestSftpUtil::test_is_file[linux-path0] PASSED
test/test_sftputil.py::TestSftpUtil::test_is_file[linux-path1] PASSED
test/test_sftputil.py::TestSftpUtil::test_id_dir[linux] PASSED
test/test_sftputil.py::TestSftpUtil::test_is_file[windows-path0] PASSED
test/test_sftputil.py::TestSftpUtil::test_is_file[windows-path1] PASSED
test/test_sftputil.py::TestSftpUtil::test_id_dir[windows] PASSED

But some parameter group is unnecessary, like windows OS + linux file path . Is there a way to define the mapping between the normal parametrize with the fixture params (I don't want to write too much if ... else ... in the test method )

is that a duplicate/variant of #681?

[markshao]

Yes , I agree with that

Thanks, Closing as duplicate of #681
