I get the following error on compile:

```
[ERROR] /usr/local/code/mapzen-android/src/test/java/com/mapzen/android/TestPelias.java:[11,15] cannot find symbol
  symbol:   method setInstance(com.mapzen.android.PeliasService)
  location: class com.mapzen.android.Pelias
```

Making TestPelias extend Pelias is one possible solution here that avoids adding a `setInstance(Pelias)` method.

```
public final class TestPelias extends Pelias {
    protected TestPelias(PeliasService service) {
        super(service);
    }

    public static PeliasService getPeliasMock() {
        PeliasService service = Mockito.mock(PeliasService.class);
        instance = new TestPelias(service);
        return service;
    }
}
```
