测试类包含以下代码：

from core.web.Base import Base

class test(Base):

    def test_test(self):
        self.driver.get("http://google.com")

测试夹具是网页驱动仍然得到错误没有找到！在

web_driver()是在Base类范围之外定义的，因此它对usefixtures不可见，因为它是test类作用域的一部分。你可以move it to conftest file，但是更好的解决方案是将web_driver移到Base内

@pytest.mark.usefixtures("web_driver")
class Base(unittest.TestCase):

    @pytest.fixture(scope="class")
    def web_driver(self, request):
        driver = webdriver.Chrome("C:/chromedriver.exe")
        request.cls.driver = driver
        yield
        driver.close()

作为旁注，它应该是driver.close()，而不是{}
