+
+## Test Implementation Highlights
+
+### Real-World Code Examples
+
+All tests use production-like code patterns:

+- Redux reducer patterns
+- REST API clients
+- Security vulnerabilities from OWASP Top 10
+- Complex business logic
+- Circular module dependencies
+
+### Comprehensive Edge Case Coverage

+- Large datasets (10+ files)
+- Special characters and Unicode
+- Long file paths and names
+- Dynamic imports
+
+### TDD Methodology
+
+- Red: Write failing test
+- Green: Minimal code to pass
+- Refactor: Improve while maintaining test passing
+
+### Error Handling
+
+- Non-existent files
+- Non-TypeScript files
+- Malformed code
+- Missing data
+- Timeout scenarios
