Vue.js testing best practices, patterns, and common gotchas.

Testing

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

Create Adaptable Composable

Create a library-grade Vue composable that accepts maybe-reactive inputs (MaybeRef / MaybeRefOrGetter) so callers can pass a plain value, ref, or getter. Normalize inputs with toValue()/toRef() inside reactive effects (watch/watchEffect) to keep behavior predictable and reactive. Use this skill when user asks for creating adaptable or reusable composables.

Vue Best Practices

MUST be used for Vue.js tasks. Strongly recommends Composition API with `<script setup>` and TypeScript as the standard approach. Covers Vue 3, SSR, Volar, vue-tsc. Load for any Vue, .vue files, Vue Router, Pinia, or Vite with Vue work. ALWAYS use Composition API unless the project explicitly requires Options API.
