## Priority Order
|
||||
|
||||
### High Priority (Do First)
|
||||
1. Adapter unit tests (critical for reliability)
|
||||
2. Guard unit tests (critical for safety)
|
||||
3. Flash loan Foundry tests (critical for security)
|
||||
4. Integration tests for main flows
|
||||
|
||||
### Medium Priority
|
||||
5. Price oracle tests
|
||||
6. Gas estimation tests
|
||||
7. Compiler edge case tests
|
||||
8. E2E fork simulation tests
|
||||
|
||||
### Low Priority (Nice to Have)
|
||||
9. Cross-chain E2E tests
|
||||
10. Performance tests
|
||||
11. Load tests
|
||||
12. Stress tests
|
||||
|
||||
## Test Execution Strategy
|
||||
|
||||
```bash
|
||||
# Run all tests
|
||||
pnpm test
|
||||
|
||||
# Run with coverage
|
||||
pnpm test --coverage
|
||||
|
||||
# Run specific test suite
|
||||
pnpm test:unit
|
||||
pnpm test:integration
|
||||
pnpm test:e2e
|
||||
|
||||
# Run Foundry tests
|
||||
forge test
|
||||
|
||||
# Run with verbose output
|
||||
pnpm test --reporter=verbose
|
||||
```
|
||||
|
||||
## Continuous Integration
|
||||
|
||||
Recommended CI/CD pipeline:
|
||||
1. Lint check
|
||||
2. Type check
|
||||
3. Unit tests
|
||||
4. Integration tests
|
||||
5. Foundry tests
|
||||
6. Coverage report
|
||||
7. Security scan (optional)
