HandlerScheduler throws NPE on schedule() in tests about rxandroid HOT 4 CLOSED

What version of Android are you running the test on?

from rxandroid.

I am running unit tests on JVM, Android Studio 3.6.2

You cannot use RxAndroid in JVM tests because it relies on Android APIs. Message.obtain is somehow returning null which is impossible on Android. Best guess is you're using something like

  testOptions {
    unitTests.returnDefaultValues = true
  }

which will make it have this behavior.

Try using Robolectric or running your tests through instrumentation on an actual emulator or device.

If you still believe it to be a problem with this library then we'll need an executable test case or sample that demonstrates the failure because as far as I can tell this is impossible behavior in normal usage.

I am using returnDefaultValues, actually seems that migrating to gradle plugin 3.6.3 solved it. The tests started passing as before. So I think the issue was with the unitTests.returnDefaultValues part most likely
