• 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
