+# Test project configuration
+
+`vitest.shared.ts`는 repository Vitest project의 공통 runner policy 정본이다.
+Package와 site의 `vitest.config.ts`에는 project 이름, source alias, plugin, dedupe,
+특수 include처럼 실제 차이만 둔다.
+
+```text
+vitest.config.ts
+`-- test.projects
+    |-- packages/*/vitest.config.ts
+    `-- site/vitest.config.ts
+
+test/vitest.shared.ts
+|-- defineNodeProject
+|-- defineNodeReactProject
+|-- defineDOMProject
+`-- defineDOMReactProject
+```
+
+- 전체 project: `npm run test:projects`
+- 선택 project: `npm run test:projects -- --project <name>`
+- package 단독: 각 workspace의 기존 `npm test` command
+- browser acceptance: `npm run browser:test`
+
+Playwright의 `setup` project는 acceptance server readiness를 먼저 증명하고
+`chrome` project가 이를 dependency로 선언한다. Unit/conformance project와 browser
+acceptance project는 서로 대체하지 않는다.
