- 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
- Choosing end-to-end testing framework for Vue apps → See testing-e2e-playwright-recommended
- Tests need to verify computed styles or real DOM events → See testing-browser-vs-node-runners
- Testing components created with defineAsyncComponent fails → See async-component-testing
- Teleported modal content can't be found in wrapper queries → See teleport-testing-complexity
