Step #6: Fixing the Existing Tests

At this point, some of our tests are broken, due to changes to the ToDoRepository constructor.

In RosterListFragmentTest (in the androidTest/ source set), in the setUp() function, replace our existing ToDoRepository setup with:

    repo = ToDoRepository(
      db.todoStore(),
      appScope,
      ToDoRemoteDataSource(OkHttpClient())
    )

This creates a valid ToDoRemoteDataSource, using a one-off copy of an OkHttpClient. Since we are not testing the import process here, these objects will not be used — they are just here to satisfy the compiler.

Then, in ToDoRepositoryTest (in the androidTest/ source set), add a new property for an implementation of ToDoRemoteDataSource:

  private val remoteDataSource = ToDoRemoteDataSource(OkHttpClient())

We can use a real implementation of ToDoRemoteDataSource and OkHttpClient here, as neither of those depend on Android — they work fine in a regular Kotlin/JVM environment.

Then, modify each underTest in ToDoRepositoryTest to pass that ToDoRemoteDataSource to our ToDoRepository constructor:

    val underTest = ToDoRepository(db.todoStore(), this, remoteDataSource)

There are three of these, one for each test function.

And, if you run RosterListFragmentTest and ToDoRepositoryTest now, they should pass.
