我正在尝试使用 xdist 并行运行多个测试，并根据用户的命令行参数（例如 --driver Remote/Chrome/etc）确定 webdriver

最终，我试图把它扔到 docker 中，以便它可以在 gitlab 管道中使用。

这是我尝试过的..

conftest.py

@pytest.fixture(scope="session")
def setup(request, selenium):
    # Get cli specified driver
    driver = selenium
    driver.get(os.environ.get('server'))

    # Collection
    session = request.node
    for item in session.items:
        cls = item.getparent(pytest.Class)
        setattr(cls.obj, "driver", driver)

    # Teardown when tests finish
    yield driver
    driver.close()

test_login.py

@pytest.mark.usefixtures("setup")
class Test:
    def test_loginValid(self, selenium):
        util.loginEnv(selenium)

这给了我错误..

========================================================================= ERRORS =========================================================================
_________________________________________________________ ERROR at setup of Test.test_loginValid _________________________________________________________ ScopeMismatch: You tried to access the 'function' scoped fixture 'selenium' with a 'session' scoped request object, involved factories

..\appdata\local\programs\python\python37-32\lib\site-packages\pytest_selenium\pytest_selenium.py:205:  def selenium(driver)

如果我尝试从 setup 夹具中删除范围，我会从 conftest.py 收到以下错误

# Collection
        session = request.node
>       for item in session.items:
E       AttributeError: 'Function' object has no attribute 'items'

tests\conftest.py:59: AttributeError

Driver log: ...\pytest-426\test_loginValid0\driver.log
URL: *** CENSORED ***
WARNING: Failed to gather log types: Message: unknown command: Cannot call non W3C standard command while in W3C mode

以前在没有 xdist 集合的情况下执行此方法。如果可能的话，我该如何完成这项工作，我做错了什么？
