Diagnosing and stabilizing flaky XCUITests
WHAT IT TESTS: handling nondeterminism in UI automation. OUTLINE: identify timing races, animations, network variance, and shared state; fix with expectations, controlled launch state, and isolation.
WHAT IT TESTS: a systematic, root-cause approach to nondeterministic tests. ANSWER OUTLINE: common causes are timing races where the test acts before the UI settles, animations, real network calls with variable latency, leftover state between runs, and reliance on volatile element ordering; stabilize by waiting on existence with expectations instead of sleeps, disabling animations, stubbing the network, resetting state via launch arguments, and isolating tests.
