tests/runtime/test_environment_utils.py:42

• Direct manipulation of os.environ in tests can lead to test isolation issues if tests run in parallel or if cleanup fails. Consider using pytest's monkeypatch fixture instead:

def test_is_development_environment(monkeypatch, env_value, expected):
    """Test is_development_environment returns correct value based on PYTHON_ENVIRONMENT."""
    if env_value is None:
        monkeypatch.delenv("PYTHON_ENVIRONMENT", raising=False)
    else:
        monkeypatch.setenv("PYTHON_ENVIRONMENT", env_value)
    
    result = is_development_environment()
    assert result == expected

This approach automatically cleans up after each test and is the pytest-recommended way to handle environment variables.

    """Test is_development_environment returns correct value based on PYTHON_ENVIRONMENT."""
    if env_value is None:
        monkeypatch.delenv("PYTHON_ENVIRONMENT", raising=False)
    else:
        monkeypatch.setenv("PYTHON_ENVIRONMENT", env_value)

    result = is_development_environment()
    assert result == expected
