Inject OkHttp using dagger2 in AndroidTest class for regestering OkHttp3IdlingResource

Issue

I have an app built with Retorift2 + Dagger2. I started to write Android UI tests using Espresso. To wait for a netwoking calls I need to register an IdlingResource. I have added dependency to OkHttp3IdlingResource.

I need to Inject a OkHttp in my test class, but as AppComponent is not in the same source directory so I can't just add

void inject(RegistrationLoginUiTest activity);

To my component.

How can I get OkHttp from the dependency graph into my test class?

Is the only way to create TestAppComponent and swap it with the AppComponent?

Solution

I have sorted out that in any case if I want to inject test class I should create TestAppComponent where I should add line:

void inject(RegistrationLoginUiTest activity);

And then swap TestAppComponent with AppComponent
