# Comprehensive Testing Suite Specification

## 1. Overview

This document defines the complete testing strategy, test suite structure, coverage requirements, and quality thresholds for the AI-Trader API service.

**Testing Philosophy:**
- **Test-Driven Development (TDD)** for critical paths
- **High coverage** (≥85%) for production code
- **Fast feedback** - unit tests run in <10 seconds
- **Realistic integration tests** with test database
- **Performance benchmarks** to catch regressions
- **Security testing** for API vulnerabilities

---

## 2. Testing Thresholds & Requirements

### 2.1 Code Coverage

| Component | Minimum Coverage | Target Coverage | Notes |
|-----------|-----------------|-----------------|-------|
| **api/job_manager.py** | 90% | 95% | Critical - job lifecycle |
| **api/worker.py** | 85% | 90% | Core execution logic |
| **api/executor.py** | 85% | 90% | Model-day execution |
| **api/results_service.py** | 90% | 95% | Data retrieval |
| **api/database.py** | 95% | 100% | Database utilities |
| **api/runtime_manager.py** | 85% | 90% | Config isolation |
| **api/main.py** | 80% | 85% | API endpoints |
| **Overall** | **85%** | **90%** | **Project minimum** |

**Enforcement:**
- CI/CD pipeline **fails** if coverage drops below minimum
- Coverage report generated on every commit
- Uncovered lines flagged in PR reviews

---

### 2.2 Performance Thresholds

| Metric | Threshold | Test Method |
|--------|-----------|-------------|
| **Unit test suite** | < 10 seconds | `pytest tests/unit/` |
| **Integration test suite** | < 60 seconds | `pytest tests/integration/` |
| **API endpoint `/simulate/trigger`** | < 500ms | Load testing |
| **API endpoint `/simulate/status`** | < 100ms | Load testing |
| **API endpoint `/results?detail=minimal`** | < 200ms | Load testing |
| **API endpoint `/results?detail=full`** | < 1 second | Load testing |
| **Database query (get_job)** | < 50ms | Benchmark tests |
| **Database query (get_job_progress)** | < 100ms | Benchmark tests |
| **Simulation (single model-day)** | 30-60s | Acceptance test |

**Enforcement:**
- Performance tests run nightly
- Alerts triggered if thresholds exceeded
- Benchmark results tracked over time

---

### 2.3 Quality Gates

**All PRs must pass:**
1. ✅ All tests passing (unit + integration)
2. ✅ Code coverage ≥ 85%
3. ✅ No critical security vulnerabilities (Bandit scan)
4. ✅ Linting passes (Ruff or Flake8)
5. ✅ Type checking passes (mypy with strict mode)
6. ✅ No performance regressions (±10% tolerance)

**Release checklist:**
1. ✅ All quality gates pass
2. ✅ End-to-end tests pass in Docker
3. ✅ Load testing passes (100 concurrent requests)
4. ✅ Security scan passes (OWASP ZAP)
5. ✅ Manual smoke tests complete

- ✅ **4 test categories:** unit, integration, performance, security
- ✅ **Performance thresholds** enforced (API endpoints < 500ms)
- ✅ **CI/CD integration** with GitHub Actions
- ✅ **Quality gates** preventing regressions

**Test count estimate:** ~150 tests total
- Unit tests: ~80
- Integration tests: ~30
- Performance tests: ~20
- Security tests: ~10
- E2E tests: ~10

**Execution time:**
- Unit tests: < 10 seconds
- Integration tests: < 60 seconds
- All tests (excluding E2E): < 2 minutes
- Full suite (including E2E): < 10 minutes

This ensures **high-quality, maintainable code** with confidence in deployments.
