feat(core): introduce TestBed.tick() (#60993)

pkozlowski-opensource · crisbeto · commit d5fd7349fb8b · 2025-04-25T12:53:23.000+02:00
This commit introduces the `TestBed.tick()` method that, similarly to the `ApplicationRef.tick()`, synchronizes state with the DOM. It can be used in unit tests to mimic framework's logic executed in production applications. The `TestBed.tick()` should be used instead of the removed `TestBed.flushEffects()`. BREAKING CHANGE: the `TestBed.flushEffects()` was removed - use the `TestBed.tick()` instead. PR Close #60993
