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

After digging through the sources, I believe things have changed in endpoints since Ezequiel Muns's (excellent) answer in 2014. For method 1 you now need to request from /_ah/api/* directly and use the correct HTTP method instead of using the /_ah/spi/* transformation. This makes the test file look like this:

from google.appengine.ext import testbed
import webtest
# ...
def setUp(self):
    tb = testbed.Testbed()
    # Setting current_version_id doesn't seem necessary anymore
    tb.activate()
    tb.init_all_stubs()
    self.testbed = tb

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

def test_endpoint_insert(self):
    app = endpoints.api_server([TestEndpoint]) # restricted is no longer required
    testapp = webtest.TestApp(app)
    msg = {...} # a dict representing the message object expected by insert
                # To be serialised to JSON by webtest
    resp = testapp.post_json('/_ah/api/test/v1/insert', msg)

    self.assertEqual(resp.json, {'expected': 'json response msg as dict'})

For searching's sake, the symptom of using the old method is endpoints raising a ValueError with Invalid request path: /_ah/spi/whatever. Hope that saves someone some time!
