解决pytest.mark自定义标签导致的warning

问题：

测试用例中添加了 @pytest.mark.login装饰器，如果不在pytest.ini中添加makers的话，就会报PytestUnknownMarkWarning: Unknown pytest.mark.login - is this a typo?  You can register custom marks to avoid this warning

@pytest.mark.usefixtures('my_setup_class')
@pytest.mark.login
@pytest.mark.parametrize('data',login.user_incorrect)
def test_login_2_wrong(self,data,my_setup_class):
    driver,login_page=my_setup_class
    login_page.clear_phone()
    login_page.clear_pwd()
    login_page.submit_userinfo(data['phone'],data['password'])
    assert (data['expected']==login_page.alert_info().text)

解决办法：
在项目下新建一个pytest.ini的配置文件，里面如下配置即可。markers=后面是标签名，如有多个，第二个开始要换行，且要缩进，不然还是会warning
