Pytest Selenium Web 驱动程序在使用 getfixturevalue 时返回为 NoneType

Question

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 返回？

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网络驱动程序，而是返回了 None.

我绞尽脑汁想解决这个问题。我认为这与我的固定装置被限定为 class 或我在我的驱动程序固定装置中使用 request 遗漏了什么有关？

如有任何帮助，我们将不胜感激。

这是我的错误日志以增加详细信息

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'

所有荣耀归于小蹄子。

正如他在评论中所说，我忘记交出我的实际 driver。

@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()
