How to unit test Google Cloud Endpoints

Question

I\'m needing some help setting up unittests for Google Cloud Endpoints. Using WebTest all requests answer with AppError: Bad response: 404 Not Found. I\'m not really sure if

Answer 1

webtest can be simplified to reduce naming bugs

for the following TestApi

import endpoints
import protorpc
import logging

class ResponseMessageClass(protorpc.messages.Message):
    message = protorpc.messages.StringField(1)
class RequestMessageClass(protorpc.messages.Message):
    message = protorpc.messages.StringField(1)


@endpoints.api(name='testApi',version='v1',
               description='Test API',
               allowed_client_ids=[endpoints.API_EXPLORER_CLIENT_ID])
class TestApi(protorpc.remote.Service):

    @endpoints.method(RequestMessageClass,
                      ResponseMessageClass,
                      name='test',
                      path='test',
                      http_method='POST')
    def test(self, request):
        logging.info(request.message)
        return ResponseMessageClass(message="response message")

the tests.py should look like this

import webtest
import logging
import unittest
from google.appengine.ext import testbed
from protorpc.remote import protojson
import endpoints

from api.test_api import TestApi, RequestMessageClass, ResponseMessageClass


class AppTest(unittest.TestCase):
    def setUp(self):
        logging.getLogger().setLevel(logging.DEBUG)

        tb = testbed.Testbed()
        tb.setup_env(current_version_id='testbed.version') 
        tb.activate()
        tb.init_all_stubs()
        self.testbed = tb


    def tearDown(self):
        self.testbed.deactivate()


    def test_endpoint_testApi(self):
        application = endpoints.api_server([TestApi], restricted=False)

        testapp = webtest.TestApp(application)

        req = RequestMessageClass(message="request message")

        response = testapp.post('/_ah/spi/' + TestApi.__name__ + '.' + TestApi.test.__name__, protojson.encode_message(req),content_type='application/json')

        res = protojson.decode_message(ResponseMessageClass,response.body)

        self.assertEqual(res.message, 'response message')


if __name__ == '__main__':
    unittest.main()
