Validating WordPress Version Management in WPScan

This test suite validates WordPress version handling in the WPScan application, focusing on version validation, vulnerability detection, and metadata management. The tests ensure proper handling of version numbers and associated security data.

Test Coverage Overview

The test suite provides comprehensive coverage of WordPress version validation and vulnerability detection:

Version number validation and instantiation
Version listing functionality
Vulnerability detection and parsing
Metadata handling including release dates and status checks

Implementation Analysis

The testing approach uses RSpec’s behavior-driven development patterns with context-based test organization. It employs mock objects and stubbing to isolate version handling logic and vulnerability data processing.

Context-based test scenarios
Shared example patterns
Mock data injection for API responses
Edge case validation

Technical Details

Testing infrastructure includes:

RSpec testing framework
Custom vulnerability data fixtures
Mocked database responses
Subject-based test organization
Before/After hooks for test setup

Best Practices Demonstrated

The test suite exemplifies robust testing practices through:

Isolated test contexts
Comprehensive edge case coverage
Clear test descriptions
Efficient test data management
Proper separation of concerns
