## 3. Test Approach
### 3.1 Test Levels
#### 3.1.1 Unit Testing
- **Framework:** Jest with TypeScript
- **Isolation:** Mocked dependencies via jest.mock()
- **Coverage Tool:** Jest --coverage
- **Minimum Coverage:** 85% statements, 80% branches
#### 3.1.2 Integration Testing
- **Scope:** Tool-to-tool interactions, Resource providers
- **Environment:** Mock Godot project structure
- **Validation:** End-to-end workflows
#### 3.1.3 Security Testing
- **Path Traversal:** Validate all path inputs
- **Command Injection:** Test ProcessPool security
- **Input Validation:** Zod schema enforcement
- **Audit Logging:** Security event capture
### 3.2 Test Types
| Test Type | Description | ISO 29119 Reference |
|-----------|-------------|---------------------|
| Functional | Verify tool behavior | 8.3.2 |
| Security | OWASP A01-A10 | 8.3.3 |
| Performance | Response time, throughput | 8.3.4 |
| Reliability | Error handling, recovery | 8.3.5 |
| Compatibility | Node.js versions, OS | 8.3.6 |
### 3.3 Test Techniques
1. **Equivalence Partitioning** - Input validation classes
2. **Boundary Value Analysis** - Limits (path length, array sizes)
3. **Error Guessing** - Common failure modes
4. **State Transition** - ProcessPool states
5. **Pairwise Testing** - Parameter combinations

## 7. Risk Assessment
### 7.1 Test Risks
| Risk | Probability | Impact | Mitigation |
|------|-------------|--------|------------|
| Godot API changes | Medium | High | Version pinning, mocks |
| Flaky tests | Low | Medium | Retry logic, isolation |
| Environment differences | Medium | Medium | Docker, CI matrix |
| Security regression | Low | Critical | Automated security tests |
### 7.2 Contingency
- Automated test retry for transient failures
- Parallel test execution for time constraints
- Mock fallbacks when Godot unavailable
---
## 8. Test Entry/Exit Criteria
### 8.1 Entry Criteria
- Code compiles without errors
- All dependencies installed
- Test environment configured
- Test data available
### 8.2 Exit Criteria
- All critical/high priority tests pass
- Coverage targets met
- No critical/high severity defects open
- Security tests pass
### 8.3 Suspension Criteria
- Build failures blocking test execution
- Critical infrastructure unavailable
- Major regression in core functionality
---
## 9. Test Case Structure
### 9.1 Naming Convention
```
{Module}.test.ts
describe('{Component}')
describe('{Feature}')
it('should {expected_behavior} when {condition}')
```
### 9.2 Test Categories
Each test file must include:
1. **Validation Tests** - Input validation with Zod schemas
2. **Happy Path Tests** - Normal operation scenarios
3. **Error Handling Tests** - Failure modes and recovery
4. **Security Tests** - Path traversal, injection attempts
5. **Boundary Tests** - Edge cases and limits
### 9.3 Example Structure
```typescript
describe('CreateScene', () => {
describe('validation', () => {
it('should return error when projectPath is missing');
it('should return error when scenePath is empty');
it('should reject path traversal attempts');
});
describe('scene creation', () => {
it('should create 2D scene with Node2D root');
it('should create 3D scene with Node3D root');
it('should create scene with custom root type');
});
describe('error handling', () => {
it('should return error when project not found');
it('should return error when scene already exists');
});
describe('security', () => {
it('should sanitize scene path');
it('should validate path within project');
});
});
```
