Labels: easy starter (was: )
> TriggerTester doesn't test timer firings

> Key: BEAM-694
> URL: https://issues.apache.org/jira/browse/BEAM-694
> Project: Beam
> Issue Type: Bug
> Components: runner-core

> TriggerTester exposes a `fireIfShouldFire(BoundedWIndow)` method. This is
> used to prompt a call to the trigger with the current state of the trigger
> tester (Input Watermarks, elements present, etc), and see if the trigger
> should fire.
> The TriggerTester should automatically call back to the trigger with the
> current state whenever a Timer fires, as specified by the current watermarks
> and any Timers set by the trigger under test. This ensures that Triggers set
> underlying timers properly, so the trigger will fire even if no additional
> elements arrive.
