XCUITest Automation Patterns

Comprehensive guide to writing reliable, maintainable UI tests with XCUITest.

Core Principle

Reliable UI tests require three things:

1. Stable element identification (accessibilityIdentifier)
2. Condition-based waiting (never hardcoded sleep)
3. Clean test isolation (no shared state)

Element Identification

The Accessibility Identifier Pattern

ALWAYS use accessibilityIdentifier for test-critical elements.
