Robolectric hanging in some instances with Android databinding
I've already raised an issue for Robolectric, but have had no response there, so perhaps SO can help me. We've a large app that uses Android Data Binding, and it currently on the rather old com.android.tools.build:gradle:2.1.3. We have Robolectric 3.8 tests that currently all work ok. We want to upgrade to a modern com.android.tools.build:gradle but when we do, some of our tests start to hang. There seems to be a particular way we're using data binding that is causing this, but outside of Robolectric it's all working ok. I've created a stripped-down sample app that shows the same issue, which is here. As there's a lot of magic that happens as part of Robolectric, and a lot of magic that happens as part of Data Binding, it makes it particularly hard to follow exactly what's going wrong. Help!

This is super hacky, sorry. You're running into some issues with Robolectric's simplified threading model, which we're working on for 4.1.
Meanwhile, this should work:
@Before
public void setup()
final ActivityController<MainActivity> activityController = buildActivity(MainActivity.class);
Robolectric.getForegroundThreadScheduler().pause();
activityController.setup();
Robolectric.getForegroundThreadScheduler().advanceToLastPostedRunnable();
Robolectric.getForegroundThreadScheduler().unPause();
