Another solution is to use Robolectric. If you want to try it, check its setup.

In your module's build.gradle, add the following

testImplementation "org.robolectric:robolectric:3.8"

android {
  testOptions {
    unitTests {
      includeAndroidResources = true
    }
  }
}

And in your test class,

@RunWith(RobolectricTestRunner.class)
public class SandwichTest {
  @Before
  public void setUp() {
  }
}

In newer versions of Robolectric (tested with 4.3) your test class should look as follows:

@RunWith(RobolectricTestRunner.class)
@Config(shadows = ShadowLog.class)
public class SandwichTest {
    @Before
    public void setUp() {
        ShadowLog.setupLogging();
    }

    // tests ...
}
