Testing JavaScript Variable Plugin Detection in WPScan

This test suite validates the JavaScript variable-based plugin detection functionality in WPScan, focusing on dynamic finder implementation for WordPress plugins. The tests ensure proper identification and version detection of plugins through JavaScript variable analysis.

Test Coverage Overview

The test coverage encompasses dynamic finder behavior for WordPress plugin detection through JavaScript variables. Key areas include:

Plugin identification through JavaScript variable analysis
Version detection capabilities
URL handling and target instantiation
Fixture-based testing scenarios

Implementation Analysis

The testing approach utilizes RSpec’s shared examples pattern to validate the JavascriptVar finder implementation. The tests leverage WPScan’s DynamicFinder framework, specifically focusing on WpItems::Finder behavior verification.

Technical implementation includes target URL configuration, fixture data management, and plugin model integration.

Technical Details

Testing infrastructure includes:

RSpec testing framework
WPScan’s custom dynamic finder framework
Fixture-based test data
Model-specific configurations for plugin detection
URL target setup and handling

Best Practices Demonstrated

The test suite demonstrates several testing best practices:

Shared example usage for consistent behavior verification
Clear separation of concerns between finder and target objects
Proper fixture organization and management
Strong typing with explicit class references
Efficient test setup with minimal dependencies
