Testing

• Setting up test infrastructure for Vue 3 projects → See testing-vitest-recommended-for-vue [blocked]

• Tests fail intermittently with race conditions → See testing-async-await-flushpromises [blocked]
• Composables using lifecycle hooks or inject fail to test → See testing-composables-helper-wrapper [blocked]
• Getting "injection Symbol(pinia) not found" errors in tests → See testing-pinia-store-setup [blocked]
• Components with async setup won't render in tests → See testing-suspense-async-components [blocked]
• Snapshot tests keep passing despite broken functionality → See testing-no-snapshot-only [blocked]
• Choosing end-to-end testing framework for Vue apps → See testing-e2e-playwright-recommended [blocked]
• Tests need to verify computed styles or real DOM events → See testing-browser-vs-node-runners [blocked]
• Testing components created with defineAsyncComponent fails → See async-component-testing [blocked]
• Teleported modal content can't be found in wrapper queries → See teleport-testing-complexity [blocked]
