我已经从我的烧瓶式API模块中单独测试了所有方法.现在我想通过实际进行API调用来测试get方法.我期待这个测试的错误400.
我的资源类
class Response(Resource):
@marshal_with(response_params_get_responses_on_job)
def get(self,filter_name=None):
try:
response = self.process_get_request(filter_name)
if not response['users']:
raise MyValidationError("No data found")
return response
except MyValidationError as err:
abort(404,message=err)
except ValueError as mistake:
abort(400,message=mistake)
我的单位测试
# TODO - Failing!
@mock.patch('application.resources.response.Response.process_get_request',autospec=True)
def test_get_400(self,process_get_request_mock):
process_get_request_mock.side_effect = ValueError("some error")
app = Flask(__name__)
app.debug = True
api = Api(app,prefix='/api/v2')
api.add_resource(Response,'/user/responses',endpoint='job_responses')
api.init_app(app)
with app.test_client() as client:
resp = client.get('/api/v2/user/responses',environ_base={'HTTP_USER_AGENT': 'Chrome'},headers={'Content-type': 'application/json'})
self.assertEqual(resp.status_code,400)
我的测试失败,因为我得到的响应是错误500
AssertionError: 500 != 400
堆栈跟踪

通过在get方法中放置一个调试点,我看到执行一直持续到中止(400,消息=错误).
然后发生了什么?为什么我的测试失败了?
最佳答案
我一直认为问题出在我的单元测试中.我错了!
问题出在我的代码中.正如米歇尔所说,我的测试已经找到了.
中止方法中的消息kwarg应该是一个字符串,而是我将它传递给异常对象.所以我在中止线上得到了一个例外.
所以我纠正了它
abort(400,message=mistake.message)
或者我也可以写
abort(400,message=str(mistake))
现在我的考试正在通过.
