can we mock EWS APIs in flask

[prashanttest-elastic]

I want to mock the exchange server. I have written a code to fetch data from the exchange server. Now I want to redirect APIs to my Flask server and return the mock data.

The exchangelib test suite uses a couple of different techniques for mocking. There's an example of service-specific mocking in

exchangelib/tests/test_protocol.py

Line 582 in 490f734

def test_resolvenames_parsing(self):

and more general HTTP mocking in

exchangelib/tests/test_autodiscover.py

Line 249 in 490f734

@requests_mock.mock(real_http=True)

@ecederstrand would it be possible to mock EWS APIs using the Flask framework?

Also, can you please provide me an endpoint used for fetching mails (also for contacts, tasks and calendars if possible) and an example of a response the APIs are returning? It would be better for us to mock those API endpoints.

I'm not sure what you're attempting to do. If you created a full EWS API clone in Flask, then I wouldn't call it mocking but rather live server testing. Just spin up your Flask server and point exchangelib to that URL instead using Configuration.service_endpoint.

If you want to redirect specific API calls to Flask and the rest to a real Exchange server, then use requests_mock.mock(real_http=True) as described above, and call into your Flask app to inject the HTTP response as needed.

If you want to see examples of actual responses from the Exchange server, then enable debug logging (see https://ecederstrand.github.io/exchangelib/#troubleshooting) and check out the XML requests and responses.
