Review comment:
It is needed here. `callAsync(...)` indirectly calls
`manualWorkerExecutor.execute(...)`, which enqueues the runnable into an
internal queue (in `ManuallyTriggeredScheduledExecutorService`) without
actually executing the runnable.
We need to call `manualWorkerExecutor.triggerAll()` to execute the runnable.
I verified that, if we remove `manualWorkerExecutor.triggerAll()`, the test
would fail due to `assertTrue(expectedError.get() instanceof
InterruptedException)` failure.
