• Tests keep breaking when refactoring component internals → See testing-component-blackbox-approach
• Tests fail intermittently with race conditions → See testing-async-await-flushpromises
• Composables using lifecycle hooks or inject fail to test → See testing-composables-helper-wrapper
• Getting "injection Symbol(pinia) not found" errors in tests → See testing-pinia-store-setup
• Components with async setup won't render in tests → See testing-suspense-async-components
• Snapshot tests keep passing despite broken functionality → See testing-no-snapshot-only
