How to use fixtures in a Class which is inherting UnitTest class in python pytest

conftest.py

import pytest

@pytest.fixture(scope="session")
def client():
    env_name = 'FLASK_ENV'
    return env_name

@pytest.fixture(scope="session")
def client_1():
    env_name = 'FLASK_ENV_1'
    return env_name

test_run.py

import pytest
import unittest

@pytest.mark.usefixtures("client")
@pytest.mark.usefixtures("client_1")
class TestStaticPages(unittest.TestCase):

    @classmethod
    def setUpClass(self):
        self.value = "ABC"

    def test_base_route(self, client, client_1):
        response = client
        assert response  == 'FLASK_ENV'
        assert client_1  == 'FLASK_ENV_1'

I am new to UnitTest in python. When I am trying to use fixtures in the test class it is failing. Could you please help me with the solution. Thanks in advance.enter image description here

This is an old question, but just in case someone stumbles over this post, I'll leave the solution I came up with here for reference.

You can define a new fixture as a wrapper, which will expose the original fixture as an attribute in your test class.

According to the code above, this would be:

import pytest
import unittest

@pytest.fixture(scope="class")
def wrapped_fixtures(request, client, client_1):
    request.cls.client = client
    request.cls.client = client_1

@pytest.mark.usefixtures("wrapped_fixtures")
class TestStaticPages(unittest.TestCase):

    @classmethod
    def setUpClass(self):
        self.value = "ABC"

    def test_base_route(self):
        response = self.client
        assert response  == 'FLASK_ENV'
        assert self.client_1  == 'FLASK_ENV_1'

Unfortunately, I don't think there is a way to do this. In the pytest documentation, it is stated that:

unittest.TestCase methods cannot directly receive fixture arguments as implementing that is likely to inflict on the ability to run general unittest.TestCase test suites.

So your client and client_1 functions can be called when the test case is run, but you can't get access to their return values.
