## Test Implementation Approach
|
||||
|
||||
### TDD Methodology
|
||||
|
||||
Each test follows the Red-Green-Refactor pattern:
|
||||
|
||||
1. **RED**: Write failing test that defines expected behavior
|
||||
2. **GREEN**: Implement minimal code to pass the test
|
||||
3. **REFACTOR**: Improve code while maintaining test passing
|
||||
|
||||
### Real-World Code Examples
|
||||
|
||||
Tests use realistic code patterns found in production:
|
||||
- React functional components with hooks
|
||||
- TypeScript interfaces and generic types
|
||||
- Redux reducer pattern violations
|
||||
- REST API clients with security issues
|
||||
- Complex business logic with multiple conditions
|
||||
- Circular module dependencies
|
||||
- Security anti-patterns from OWASP Top 10
|
||||
|
||||
### Edge Case Coverage
|
||||
|
||||
Comprehensive testing of boundary conditions:
|
||||
- Empty/null inputs
|
||||
- Malformed data and invalid formats
|
||||
- Boundary values (0%, 100%, thresholds)
|
||||
- Large datasets (10+ files)
|
||||
- Special characters and Unicode
|
||||
- Long function names and file paths
|
||||
- Dynamic imports and lazy loading
|
||||
|
||||
### Error Resilience
|
||||
|
||||
Each analyzer gracefully handles:
|
||||
- Non-existent files
|
||||
- Non-TypeScript files (JSON, Markdown)
|
||||
- Malformed TypeScript code
|
||||
- Missing configuration data
|
||||
- Incomplete coverage reports
|
||||
- Timeout scenarios
|
||||
|
||||

Tests detection of cross-site scripting risks.
|
||||
|
||||
**Dangerous Patterns:**
|
||||
```typescript
|
||||
// React
|
||||
- dangerouslySetInnerHTML={{ __html: userInput }}
|
||||
|
||||
// DOM manipulation
|
||||
- element.innerHTML = userInput
|
||||
- element.innerText = userInput
|
||||
|
||||
// Code execution
|
||||
- eval(userInput)
|
||||
- Function(userInput)()
|
||||
```
|
||||
|
||||
**Test Cases:**
|
||||
```typescript
|
||||
it('should detect dangerouslySetInnerHTML usage', ...)
|
||||
it('should detect innerHTML assignments', ...)
|
||||
it('should detect eval() usage', ...)
|
||||
it('should detect potential XSS with user input in innerHTML', ...)
|
||||
```
|
||||
|
||||
**Severity Levels:**
|
||||
```typescript
|
||||
// Critical patterns
|
||||
- eval() usage: severity critical
|
||||
- dangerouslySetInnerHTML: severity high (with user input: high)
|
||||
- innerHTML assignment: severity high
|
||||
- XSS risk patterns: severity high
|
||||
```
|
||||
|
||||
#### 3. Realistic Security Scenarios (3 tests)
|
||||
Tests with real-world insecure code patterns.
|
||||
|
||||
**Scenario 1: Insecure API Client**
|
||||
```typescript
|
||||
// Multiple issues detected
|
||||
const API_KEY = 'sk_live_abc123def456xyz' // Hardcoded secret
|
||||
const password = 'admin@password123' // Hardcoded secret
|
||||
document.getElementById('content').innerHTML = userInput // XSS risk
|
||||
eval(code) // Critical: eval usage
|
||||
```
|
||||
|
||||
**Scenario 2: Configuration File with Secrets**
|
||||
```typescript
|
||||
DATABASE_URL: 'postgresql://user:password123@localhost:5432/mydb'
|
||||
SECRET_KEY: 'my-super-secret-key-for-jwt'
|
||||
API_PASSWORD: 'admin123!@#'
|
||||
oauth_token: 'ghp_xxxxxxxxxxxxxxxxxxxxxxxxxxxx'
|
||||
apiKey: 'AIzaSyAbCdEfGhIjKlMnOpQrStUvWxYzAb'
|
||||
```
|
||||
|
||||
**Scenario 3: Component with Mixed XSS Risks**
|
||||
```typescript
|
||||
// Vulnerable patterns
|
||||
dangerouslySetInnerHTML={{ __html: userHTML }}
|
||||
element.innerHTML = html
|
||||
|
||||
// Safe patterns
|
||||
dangerouslySetInnerHTML={{ __html: sanitizeHtml(userHTML) }}
|
||||
```
|
||||
|
||||
#### 4. Performance Issues Detection (5 tests)
|
||||
Tests detection of performance anti-patterns.
|
||||
|
||||
**Detected Issues:**
|
||||
|
||||
| Issue | Severity | Impact |
|
||||
|-------|----------|--------|
|
||||
| Inline function in JSX | medium | Unnecessary re-renders |
|
||||
| Missing key prop in lists | high | Rendering issues |
|
||||
| Inline objects in props | medium | Unnecessary re-renders |
|
||||
| Inline arrays in props | medium | Unnecessary re-renders |
|
||||
|
||||
**Test Cases:**
|
||||
```typescript
|
||||
it('should detect inline function definitions in JSX', ...)
|
||||
it('should detect missing keys in list rendering', ...)
|
||||
it('should detect inline objects in JSX props', ...)
|
||||
it('should detect inline array literals in JSX', ...)
|
||||
it('should report performance issue impact', ...)
|
||||
```
|
||||
|
||||
**Examples:**
|
||||
|
||||
```typescript
|
||||
// Issue: Inline function
|
||||
<button onClick={() => onClick()}>Click</button> // Creates new function each render
|
||||
|
||||
// Issue: Missing key
|
||||
{items.map((item) => <li>{item.name}</li>)} // No unique key provided
|
||||
|
||||
// Issue: Inline object
|
||||
<Child style={{ color: 'red', fontSize: 14 }} /> // New object each render
|
||||
|
||||
// Issue: Inline array
|
||||
<Dialog actions={['OK', 'Cancel']} /> // New array each render
|
||||
```
|
||||
|
||||
#### 5. Findings Generation (3 tests)
|
||||
Generates security findings with location and remediation.
|
||||
|
||||
```typescript
|
||||
- Vulnerability findings: Include update recommendations
|
||||
- Code pattern findings: Include remediation guidance
|
||||
- Location findings: Include file and line number
|
||||
```
|
||||
|
||||
#### 6. Score Calculation (5 tests)
|
||||
Calculates security score based on vulnerabilities.
|
||||
|
||||
**Score Calculation:**
|
||||
```typescript
|
||||
score = 100
|
||||
score -= criticalVulns * 25
|
||||
score -= highVulns * 10
|
||||
score -= criticalPatterns * 15
|
||||
score -= highPatterns * 5
|
||||
score -= Math.min(performanceIssues.length * 2, 20)
|
||||
score = Math.max(0, score) // Minimum 0
|
||||
```
|
||||
|
||||
**Status Assignment:**
|
||||
```typescript
|
||||
- pass: score >= 80
|
||||
- warning: 70 <= score < 80
|
||||
- fail: score < 70
|
||||
```
|
||||
|
||||
#### 7. Error Handling and Edge Cases (5 tests)
|
||||
Tests robustness with various inputs.
|
||||
|
||||
```typescript
|
||||
- Empty file paths array
|
||||
- Non-TypeScript files (JSON, Markdown)
|
||||
- Non-existent files
|
||||
- Files with special characters and Unicode
|
||||
- Execution time measurement
|
||||
```
|
||||
|
||||
#### 8. Multiple Issues Scenarios (3 tests)
|
||||
Tests comprehensive security analysis.
|
||||
|
||||
```typescript
|
||||
- Multiple issues in single file
|
||||
- Complete project analysis
|
||||
- Limiting findings to top 20 issues
|
||||
```
|
||||
|
||||
#### 9. Safe Code Recognition (2 tests)
|
||||
Verifies that secure code receives passing scores.
|
||||
|
||||
**Safe Component Example:**
|
||||
```typescript
|
||||
export const SafeComponent: React.FC<Props> = ({ title, onClick }) => {
|
||||
const [count, setCount] = useState(0);
|
||||
|
||||
const handleClick = () => {
|
||||
setCount(count + 1);
|
||||
onClick();
|
||||
};
|
||||
|
||||
return (
|
||||
<div className="component">
|
||||
<h1>{title}</h1>
|
||||
<p>Count: {count}</p>
|
||||
<button onClick={handleClick}>Increment</button>
|
||||
</div>
|
||||
);
|
||||
};
|
||||
```
|
||||
|
||||
**Safe Utility Example:**
|
||||
```typescript
|
||||
export const add = (a: number, b: number): number => a + b;
|
||||
export const isEmpty = (str: string): boolean => str.length === 0;
|
||||
export const isValidEmail = (email: string): boolean =>
|
||||
/^[^\s@]+@[^\s@]+\.[^\s@]+$/.test(email);
|
||||
```

|
||||
- **Total Tests:** 139
|
||||
- **Pass Rate:** 100%
|
||||
- **Execution Time:** ~32 seconds
|
||||
- **Coverage:** Comprehensive coverage of all analyzer functionality
|
||||
|
||||
## Key Testing Patterns
|
||||
|
||||
### 1. TDD Approach
|
||||
Each test follows Red-Green-Refactor pattern:
|
||||
- RED: Test fails initially
|
||||
- GREEN: Minimal code to pass
|
||||
- REFACTOR: Improve while keeping tests passing
|
||||
|
||||
### 2. Real Code Examples
|
||||
Tests use realistic code patterns that appear in production:
|
||||
- React components with hooks
|
||||
- TypeScript interfaces and types
|
||||
- Complex dependency chains
|
||||
- Security vulnerabilities from OWASP Top 10
|
||||
|
||||
### 3. Edge Case Coverage
|
||||
Tests include:
|
||||
- Empty/null inputs
|
||||
- Malformed data
|
||||
- Boundary conditions
|
||||
- Large datasets
|
||||
- Special characters and Unicode
|
||||
|
||||
### 4. Error Handling
|
||||
Tests verify:
|
||||
- Graceful degradation
|
||||
- Proper error messages
|
||||
- Execution time tracking
|
||||
- Resource cleanup
|
||||
|
||||
## Future Test Enhancements
|
||||
|
||||
1. **Integration Tests**: Combine multiple analyzers in workflows
|
||||
2. **Performance Benchmarks**: Track test execution time trends
|
||||
3. **Snapshot Testing**: Validate report format consistency
|
||||
4. **Property-Based Testing**: Generate random code patterns
|
||||
5. **Visual Regression**: Test report rendering with different themes
|
||||
|
||||
## Debugging Failed Tests
|
||||
|
||||
### Common Issues
|
||||
|
||||
1. **Temporary Directory Cleanup**
|
||||
```bash
|
||||
# Clear any leftover temp directories
|
||||
rm -rf /Users/rmac/Documents/GitHub/snippet-pastebin/tests/temp-*
|
||||
```
|
||||
|
||||
2. **File System Race Conditions**
|
||||
- Use `beforeEach/afterEach` hooks
|
||||
- Ensure directory cleanup completes before next test
|
||||
|
||||
3. **Working Directory Issues**
|
||||
- Save original `process.cwd()`
|
||||
- Restore after test: `process.chdir(originalCwd)`
|
||||
|
||||
### Debug Mode
|
||||
```bash
|
||||
npm test -- --verbose tests/unit/lib/quality-validator/analyzers
|
||||
```
|
||||
|
||||
## Contributing New Tests
|
||||
|
||||
When adding new analyzer functionality:
|
||||
|
||||
1. Follow existing test structure and naming conventions
|
||||
2. Include tests for:
|
||||
- Happy path (success case)
|
||||
- Error cases
|
||||
- Edge cases
|
||||
- Integration scenarios
|
||||
3. Ensure tests are isolated (no cross-test dependencies)
|
||||
4. Clean up resources in `afterEach` hooks
|
||||
5. Document expected behavior in comments
