谁能帮我弄清楚为什么驱动程序在我的 pytest.hookimpl 夹具中作为 NoneType 回来？

这是我的 conftest.py

@pytest.fixture()
def chrome_driver_init(request, path_to_chrome):
    driver = webdriver.Chrome(options=opts, executable_path=path_to_chrome)
    request.cls.driver = driver
    page_object_init(request, driver)
    driver.get(URL)
    driver.maximize_window()
    yield
    driver.quit()


# Adds a screenshot to the pytest-html report for a failed test
@pytest.hookimpl(hookwrapper=True)
def pytest_runtest_makereport(item, call):
    pytest_html = item.config.pluginmanager.getplugin("html")
    outcome = yield
    report = outcome.get_result()
    extra = getattr(report, "extra", [])
    if report.when == "call":
        feature_request = item.funcargs['request']
        driver = feature_request.getfixturevalue('chrome_driver_init')
        nodeid = item.nodeid
        xfail = hasattr(report, "wasxfail")
        if (report.skipped and xfail) or (report.failed and not xfail):
            file_name = f'{nodeid}_{datetime.today().strftime("%Y-%m-%d_%H:%M")}.png'.replace("/", "_").replace("::", "_")
            img_path = os.path.join(REPORT_PATH, "screenshots", file_name)
            driver.save_screenshot(img_path)
            extra.append(pytest_html.extras.image(img_path))
        report.extra = extra

错误发生在，driver.save_screenshot()但我假设真正的问题是

driver = feature_request.getfixturevalue('chrome_driver_init')实际上并没有返回我的 webdriver 而是返回None.

我绞尽脑汁试图解决这个问题。我认为这与我的灯具被限定为类有关，或者我request在我的驱动程序灯具中使用了一些东西？

任何帮助，将不胜感激。

这是我的错误日志以获取更多详细信息

INTERNALERROR>   File "~/pytest_project\scr\tests\conftest.py", line 57, in pytest_runtest_makereport
INTERNALERROR>     driver.save_screenshot(img_path)
INTERNALERROR> AttributeError: 'NoneType' object has no attribute 'save_screenshot'

所有的荣耀都归于胡夫林。

正如他在评论中所说，我忘了让我的实际司机。

@pytest.fixture()
def chrome_driver_init(request, path_to_chrome):
    driver = webdriver.Chrome(options=opts, executable_path=path_to_chrome)
    request.cls.driver = driver
    page_object_init(request, driver)
    driver.get(URL)
    driver.maximize_window()
    yield driver
    driver.quit()
