963 markdown files reformatted with the repository's pinned prettier so pnpm format:check covers the folded tree like every other repo file. The formatter's embedded-language pass also normalized code fences (TS semicolons, closed HTML tags in examples, lowercased CSS hex colors, one renumbered list that skipped an index). Alphanumeric token deltas vs the fold commit were audited file-by-file; all are formatter-equivalent markup normalizations plus the four sanitized skills.

|
|
### Testing
|
|
|
|
- Setting up test infrastructure for Vue 3 projects → See [testing-vitest-recommended-for-vue](reference/testing-vitest-recommended-for-vue.md)
|
|
- Tests keep breaking when refactoring component internals → See [testing-component-blackbox-approach](reference/testing-component-blackbox-approach.md)
|
|
- Tests fail intermittently with race conditions → See [testing-async-await-flushpromises](reference/testing-async-await-flushpromises.md)
|
|
- Composables using lifecycle hooks or inject fail to test → See [testing-composables-helper-wrapper](reference/testing-composables-helper-wrapper.md)
|
|
- Getting "injection Symbol(pinia) not found" errors in tests → See [testing-pinia-store-setup](reference/testing-pinia-store-setup.md)
|
|
- Components with async setup won't render in tests → See [testing-suspense-async-components](reference/testing-suspense-async-components.md)
|
|
- Snapshot tests keep passing despite broken functionality → See [testing-no-snapshot-only](reference/testing-no-snapshot-only.md)
|
|
- Choosing end-to-end testing framework for Vue apps → See [testing-e2e-playwright-recommended](reference/testing-e2e-playwright-recommended.md)
|
|
- Tests need to verify computed styles or real DOM events → See [testing-browser-vs-node-runners](reference/testing-browser-vs-node-runners.md)
|
|
- Testing components created with defineAsyncComponent fails → See [async-component-testing](reference/async-component-testing.md)
|
|
- Teleported modal content can't be found in wrapper queries → See [teleport-testing-complexity](reference/teleport-testing-complexity.md)
