描述

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. This is sufficient to test shouldFire of the TriggerStateMachine under test, but does not test that the onElement method sets an appropriate timer to cause such an interrogation to occur.

研究方向
Examine the TriggerTester class, particularly the fireIfShouldFire method. Understand how the trigger state machine works to determine what timer setting methods need to be added. Look for any existing tests related to timers in the Beam codebase. The original Jira issue (BEAM 694) may contain additional context that clarifies the expected behavior.
