# tOS Test Infrastructure
## Frontend (apps/web) - Vitest
### Configuration
- `vitest.config.ts` at project root of apps/web
- Uses `@vitejs/plugin-react` for JSX transform
- jsdom environment for DOM testing
- `globals: true` so `describe/it/expect` are global
- Path alias `@` -> `./src` matching tsconfig
- CSS disabled in tests (`css: false`)
- Setup file: `src/test/setup.ts` imports `@testing-library/jest-dom/vitest`
### Dependencies (devDependencies)
- vitest ^2.1.8
- @testing-library/react ^16.1.0
- @testing-library/jest-dom ^6.6.3
- @testing-library/user-event ^14.5.2
- @vitejs/plugin-react ^4.3.4
- jsdom ^25.0.1
### Test Files
- `src/lib/utils.test.ts` - Tests for cn(), getInitials(), capitalize(), truncate(), safeJsonParse(), generateId(), isServer(), isClient()
- `src/components/ui/badge.test.tsx` - Badge component rendering with all variants
- `src/hooks/use-toast.test.ts` - Tests reducer logic and toast() function
### Run Commands
```bash
pnpm --filter web test # vitest run
pnpm --filter web test:watch # vitest (watch mode)
```
## Backend (apps/api) - Jest
### Configuration
- Inline in `package.json` under `"jest"` key
- ts-jest transform for TypeScript
- Node test environment
- Module alias: `@/` -> `<rootDir>/` (rootDir = src)
- Test regex: `.*\.spec\.ts$`
### Dependencies (already present)
- jest ^29.7.0
- ts-jest ^29.1.1
- @nestjs/testing ^10.3.0
- @types/jest ^29.5.11
- supertest ^6.3.3
### Test Files
- `src/health/health.controller.spec.ts` - Health controller (check, liveness, readiness)
- `src/common/services/encryption.service.spec.ts` - EncryptionService (encrypt/decrypt, objects, empty strings, generateKey, init)
### Test Patterns for NestJS
- Use `Test.createTestingModule()` for DI setup
- Mock all dependencies with `{ provide: X, useValue: mockX }`
- Call `module.get<T>(T)` to get the instance under test
- For services with `onModuleInit()`, call it manually in `beforeEach`
- Use `jest.clearAllMocks()` in `afterEach`
### Run Commands
```bash
pnpm --filter api test # jest
pnpm --filter api test:watch # jest --watch
pnpm --filter api test:cov # jest --coverage
```
