Android developers often fetch data from HTTP endpoints to display it on the device. These endpoints can be a major source of frustration, especially when they are backed by complex legacy systems. One easy source of testing that will actually speed the pace of development from the beginning is end-to-end integration tests with those endpoints. However, in the end the tests can only be as stable as the environment they’re testing. I shall present a framework for creating these tests and partially automate creating an OkHttp interceptor that will provide mocked responses to ensure the stability of the tests. With this framework and this interceptor, integration tests can distinguish between a failure caused by a change to the behavior of the endpoint and a failure caused by a change to the application source.
