Here in our TDD course we have createUser test. This section has an error and missing information in the header.
Do the following set up in the code
1 . There was no `avatar` added to the actual "createUser" call's body in the remote data source, but in the test, we were expecting that a call was made with avatar in the body, in the "verify(() => http://client.post(...));" part
2 . There was no headers in the test, but we used headers in the main code, so, there was a conflict in the verify again, also, we missed the header in the "when" stub in the test, and again, conflict
If you add header info the issue should be solved.
