Demo project for using MockWebServer for unit tests. This project also hints on mocking out views while testing using
Mockito and focuses on the usage of
MockWebServer for writing tests.
MockWebServerfor writing unit tests.
Most of the demos out there make use of
MockWebServer for writing
androidTests and adding custom
JUnitTestRunners and are more focused on integration testing. Nowadays, MVP architecture is getting adopted by many android developers and we like our
logic layer to be tested properly. MVP enables proper testing of the logic layer via unit tests and separates it from the pains of testing the android UI. While testing, we should not hit the actual web server. If we hit actual server while testing, then the tests become flaky as they depend upon the actual network availability. This project shows how we can write unit tests for our
Presenters / Models easily. It also shows how we can test certain error conditions properly with the use of
MockWebServer which becomes as easy as just hitting the actual remote server.

This project has a separate module called
mocks. Our android application module
app has a
testCompile dependency on the
mocks module. Also, created a
LocalResponseDispatcher which takes care of the local API needs.
MockWebserver to test the API calls in our ModelRepository (
PokemonDataSource) and we use
Mockitoto test our Presenter (
MainPresenterImpl) by mocking out the view. We have also written some demo tests using
MockWebServer just to show how same thing can be achieved using
To run tests :
./gradlew clean test
