 ## Testing
 
-Currently no automated test suite. Manual testing checklist:
+### Automated Tests
+
+Unit tests are located in `tests/unit/` and run via [Vitest](https://vitest.dev/):
+
+```bash
+npm test                # Run all tests
+npm run test:watch      # Watch mode
+npm run test:coverage   # Coverage report
+```
+
+Current test files:
+- `gyazoUploader.test.ts` — Gyazo uploader (upload success, error handling, field omission)
+- `imageStore.test.ts` — Provider registry and `normalizeId()` alias resolution
+- `isAlreadyHosted.test.ts` — Hosted-URL detection for all providers
+- `imageTagRegex.test.ts` — Markdown/Wiki image tag regex matching
+- `uploaderUtils.test.ts` — Path template generation and domain customization
+- `webImageDownloader.test.ts` — Web image download logic
+- `mermaidProcessor.test.ts` — Mermaid-to-PNG conversion
+- `mermaidRegex.test.ts` — Mermaid code block regex matching
+
+### Manual Testing Checklist
 
 1. Test each storage provider with sample images
 2. Verify path variable substitution works correctly
