## Test Coverage Thresholds

Both frontend and backend enforce **60% minimum coverage**:
- Lines: 60%
- Functions: 60%
- Branches: 60%
- Statements: 60%

## GitHub Actions Workflow Triggers

### Test & Validate Workflow
**Triggers:**
- Pull requests to: `main`, `beta`, `develop`
- Pushes to: `main`, `beta`

**Path filters:**
- `dashboard/**`
- `mcp/**`
- `.github/workflows/test.yml`

### Release Workflow
**Triggers:**
- Tags matching: `YYYY.MM.DD` or `YYYY.MM.DD.N`

**Enhanced with:**
- Pre-release testing job (must pass)
- Build validation
- Docker image creation

## Next Steps

### For Development
1. **Install Dependencies**
   ```bash
   cd dashboard/backend && npm install
   cd dashboard/frontend && npm install
   ```

2. **Run Tests Locally**
   ```bash
   # Backend
   cd dashboard/backend
   npm test

   # Frontend
   cd dashboard/frontend
   npm test
   ```

3. **Write Tests for New Features**
   - Follow examples in `BetSlip.test.tsx`, `format.test.ts`, `betSlipSlice.test.ts`
   - Use test utilities from `src/test/test-utils.tsx`
   - Aim for 60%+ coverage

### For CI/CD
1. **Configure Codecov** (Optional)
   - Add `CODECOV_TOKEN` to GitHub repository secrets
   - Coverage reports will be uploaded automatically

2. **Test PR Workflow**
   - Create a test PR to verify workflow execution
   - Check that tests run and results are posted

3. **Test Release Workflow**
   - Push a test tag to verify release process
   - Confirm tests block release on failure

### For Team
1. **Review Documentation**
   - Read `dashboard/TESTING.md`
   - Review `docs/CI-CD-TESTING.md`

2. **Update Team Workflow**
   - Add pre-commit testing to development process
   - Require tests for all new features
   - Review coverage reports in PRs
