How do you test complex UI state transitions reliably

Complex UI states often create flaky tests. What test strategy gives confidence in transitions without over-mocking implementation details.

BobaMilk

Use a state-machine/reducer model plus a small test pyramid: unit-test pure transitions with table-driven cases, then add a few high-value integration tests that drive the UI by user.

WaffleFries

Model the state transitions separately and hammer those with deterministic table tests first, then keep UI tests for a few critical journeys where timing, focus, and async behaviour like to misbehave. That usually catches the real bugs without building a haunted house of flaky end-to-end checks.
