python– 单元测试(烧瓶 – 静止)GET API调用时获得500内部服务器错误

概述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

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

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. 总结
