问答 appium+python 断言，使用 self.assertIsNone (element,'存在 element,Fail'),若 element 不存在，用例不会 pass，脚本报错：selenium.common.exceptions.NoSuchElementException: Message: An element could not be located on the page using the given search parameters.
class case_mypushlish_return(unittest.TestCase):
def setUp(self):
public.setUp.setUp(self)
def tearDown(self):
self.dr.quit()
@user1imer
def test_mypushlish_return(self):
self.assertIsNone(self.dr.find_element_by_name(taskname_2),'存在taskname_2,Fail')
if __name__ == '__main__':
suite = unittest.TestLoader().loadTestsFromTestCase(case_mypushlish_return)
unittest.TextTestRunner(verbosity=2).run(suite)
报错：

有人知道 assertIsNone 的正确用法吗？
已经换种方式解决
class mytest(unittest.TestCase):
##初始化工作
def setUp(self):
pass
def tearDown(self):
self.dr.quit()
def testfun(self):
pass_1 = False
try:
self.dr.find_element_by_id('11')
print('pass')
except:
pass_1 = True
print(pass_1)
if pass_1 == True:
self.assertIsNone(None, '存在wulh发起的任务,Fail')
else:
self.assertIsNone(not None, '存在wulh发起的任务,Fail')
if __name__ == '__main__':
suite = unittest.TestLoader().loadTestsFromTestCase(mytest)
unittest.TextTestRunner(verbosity=2).run(suite)
