+- Queue failed jobs for retry with appropriate delays
+
+**3. Data Validation and Integrity Errors**
+- Validate all input data at API boundaries
+- Implement database constraints and transaction rollbacks
+- Provide clear error messages for validation failures
+
+**4. Authentication and Authorization Errors**
+- Implement secure session management with proper timeouts
+- Provide clear feedback for permission denied scenarios
+- Log security-related errors for monitoring
+
+## Testing Strategy
+
+### Dual Testing Approach
+
+The platform requires both unit testing and property-based testing for comprehensive coverage:
+
+**Unit Tests:**
+- Verify specific examples and edge cases
+- Test integration points between microservices
+- Validate error conditions and boundary cases
+- Focus on concrete scenarios and known failure modes
+
+**Property-Based Tests:**
+- Verify universal properties across all inputs
+- Test system behavior with randomized data
+- Validate correctness properties from the design document
+- Ensure comprehensive input coverage through randomization
+
+### Property-Based Testing Configuration
+
+**Framework:** fast-check (JavaScript/TypeScript property-based testing library)
+**Configuration:**
+- Minimum 100 iterations per property test
+- Each test tagged with: **Feature: website-cloning-platform, Property {number}: {property_text}**
+- Custom generators for domain-specific data (URLs, HTML structures, CSS rules)
+- Shrinking enabled to find minimal failing examples
+
+**Example Test Structure:**
+```typescript
+// Feature: website-cloning-platform, Property 1: BFS Page Discovery
+fc.assert(fc.property(
+  websiteStructureGenerator(),
+  (website) => {
+    const crawler = new IntelligentCrawler();
+    const result = crawler.crawlWebsite(website.rootUrl, defaultConfig);
+    return verifyBFSOrder(result.pages) && 
+           verifyAllPagesFound(website, result.pages);
+  }
+), { numRuns: 100 });
+```
+
+### Testing Infrastructure
+
+**Test Environment:**
+- Dockerized test environment with isolated databases
+- Mock external services (S3, payment providers, CDNs)
+- Automated test data generation and cleanup
+- Performance testing with realistic load patterns
+
+**Continuous Integration:**
+- Automated test execution on all pull requests
+- Property-based test results tracked and analyzed
+- Performance regression detection
+- Security vulnerability scanning
