Question

Answer 1

In addition to other answers. There is an option to overwrite pytest_generate_tests in conftest.py and set ENV variables there.

For example, add following into conftest.py:

import os

def pytest_generate_tests(metafunc):
    os.environ['TEST_NAME'] = 'My super test name| Python version {}'.format(python_version)

This code will allow you to grab TEST_NAME ENV variable in your tests application. Also you could make a fixture:

import os
import pytest

@pytest.fixture
def the_name():
    return os.environ.get('TEST_NAME')

Also, this ENV variable will be available in your application.
