我正在使用selenium和python创建一个自动化框架，因此在conftest.py文件中我使用了fixture，但是当我通过cmd行运行测试用例时却出现错误
我已经一遍又一遍地检查了，但我没有得到此错误的根本原因
此代码在我的conftest.py文件下
import pytest
@pytest.fixture(scope="class")
def test_setup(request):
from selenium import webdriver
browser = request.config.getoption("--browser")
if browser == "chrome":
driver = webdriver.Chrome(executable_path="/home/akash/PycharmProjects/AutomationFramework/drivers/chromedriver")
request.cls.driver = driver
yield
driver.quit()
下面是测试用例文件
@pytest.mark.usefixtures("test_setup")
class TestLogin:
def test_login(self):
driver = self.driver
driver.get(utils.URL)
当我以python -m pytest命令运行时，出现以下错误 但是，它应该已经打开浏览器并完成工作
我得到的错误

答案 0 :(得分：1)
我得到的解决方案只是因为缩进，所以在我写
import pytest
@pytest.fixture(scope="class")
def test_setup(request):
from selenium import webdriver
browser = request.config.getoption("--browser")
if browser == "chrome":
driver = webdriver.Chrome(executable_path="/home/akash/PycharmProjects/AutomationFramework/drivers/chromedriver")
request.cls.driver = driver
yield
driver.quit()
所以在上面我要设置可执行路径的那一行下面的语句中，下一行是针对我创建的函数的，因此这些语句位于该函数的下面，而不是if语句，这就是为什么它导致上述错误的原因。
