Python test - AttributeError：'NoneType‘对象没有'status_code’属性
Python test - AttributeError：'NoneType‘对象没有'status_code’属性
提问于 2021-06-02 20:52:14
用python编写一些单元测试，已经将其简化为一些函数，以关注这个问题。
所以有两个函数是这样的
def function_to_throw_http_error():
logger.info("function_to_throw_http_error")
def function_to_catch_http_error():
try:
function_to_throw_http_error()
except HTTPError as http_err:
logger.error(f"HTTP error occurred external service: {http_err}")
return {"statusCode": http_err.response.status_code, "body": http_err.response.reason}测试是这样的
@patch(
"functions.my_file.function_to_throw_http_error", Mock(side_effect=HTTPError(Mock(status_code=404), 'error')),
)
def test_catching_http_error_reposnse(self):
response = function_to_catch_http_error()
self.assertTrue('error' in str(response))但是当我运行测试时，我得到了以下错误
> return {"statusCode": http_err.response.status_code, "body": http_err.response.reason}
E AttributeError: 'NoneType' object has no attribute 'status_code'回答 1

#the builtins module itself has no HTTPError as default class
import builtins
print(dir(builtins))
#just printing out the exception classes from buitins directory

# so in order to use HTTPError use the requests module
import requests
try:

except requests.HTTPError as exception:
#print your exception using print(exception)
