Python 3.x 我得到'；属性错误：'；TestClass'；对象没有属性'；获取''；在测试用例执行期间

我正在尝试使用pytest创建一个测试用例。 我在测试用例中使用pytest夹具。但每次执行代码时，都会出现一个错误：

    def test_case(webdriver_definition):
    driver = webdriver_definition
    baseURL = 'https://www.di.fm/'
>   driver.get(baseURL)
E   AttributeError: 'TestClass' object has no attribute 'get'

我的测试班

class TestClass:

@pytest.fixture(autouse=True)
def webdriver_definition(self):
    driver = webdriver.Chrome(executable_path="D:/Selenium webdriver/chromedriver_win32/chromedriver.exe")
    driver.implicitly_wait(2)
    driver.maximize_window()
    print('=================Driver initialized===================')
    return driver

def test_case(webdriver_definition):
    driver = webdriver_definition
    baseURL = 'https://www.di.fm/'
    driver.get(baseURL)
    home_button = sd.find_element("//nav[@id='side-nav']/ul//span[.='Home']")
    if home_button:
        print(f'Element {home_button} was found\n')
    else:
        print(f'Element {home_button} was not found')
    home_button.click()
    time.sleep(2)
    driver.quit()

---

这是因为Python将

self

作为

test\u case（）

中的第一个参数，因此

webdriver\u定义

被视为

self

，即

TestClass

class TestClass:

    @pytest.fixture(autouse=True)
    def webdriver_definition(self):
        driver = webdriver.Chrome(executable_path="D:/Selenium webdriver/chromedriver_win32/chromedriver.exe")
        # ...
        return driver

    def test_case(self, webdriver_definition):
        driver = webdriver_definition
        baseURL = 'https://www.di.fm/'
        driver.get(baseURL)
