Testing Plugin Query Parameter Detection in WPScan

This test suite evaluates the QueryParameter plugin finder functionality in WPScan, focusing on passive and aggressive detection methods. The tests verify the behavior of plugin version detection through query parameter analysis, ensuring reliable WordPress plugin discovery.

Test Coverage Overview

The test suite covers essential aspects of plugin detection via query parameters in WPScan. Key areas include:

Passive detection methodology validation
Aggressive scanning capabilities setup
URL parameter handling verification
Target object initialization testing

Implementation Analysis

The testing approach utilizes RSpec’s behavior-driven development framework to validate the QueryParameter finder class. The implementation leverages RSpec’s described_class pattern and subject/let declarations for clean test organization and dependency management.

Tests are structured using nested describe blocks with explicit context separation between passive and aggressive scanning methods.

Technical Details

Testing infrastructure includes:

RSpec as the primary testing framework
Fixture data management for plugin version testing
Dynamic finder configuration setup
Mock URL and target object initialization
Frozen string literal pragma implementation

Best Practices Demonstrated

The test suite exemplifies several testing best practices including proper isolation of test subjects, clear separation of concerns, and effective use of RSpec’s DSL. Notable practices include fixture organization, explicit subject declaration, and structured test hierarchies that mirror the actual class functionality.

The code demonstrates clean organization with well-defined test boundaries and proper setup of test dependencies.
