Testing String-to-Symbol Classification Methods in WPScan

This test suite validates the classify_slug helper method in WPScan, focusing on string-to-symbol conversion with various input formats. The tests ensure proper handling of different slug formats including standard text, hyphenated strings, numeric prefixes, and multi-byte characters.

Test Coverage Overview

The test suite provides comprehensive coverage of the classify_slug method’s capabilities across diverse input scenarios.

Standard slug conversion testing
Hyphenated string handling
Numeric prefix processing
Special character management
Multi-byte character support (Japanese text)

Implementation Analysis

The implementation utilizes RSpec’s context-based testing pattern with a hash-driven test structure. This approach enables concise testing of multiple input-output pairs while maintaining clear test organization.

The tests leverage RSpec’s expect syntax with eql matcher for precise comparison of generated symbols against expected values.

Technical Details

Testing Framework: RSpec
Test Style: Unit Testing
Data Structure: Hash-based test cases
Assertion Method: expect().to eql
Code Organization: Context blocks for each test case

Best Practices Demonstrated

The test suite exemplifies several testing best practices including data-driven test case definition, clear input-output mapping, and comprehensive edge case coverage.

DRY principle through iterative testing
Explicit context descriptions
Consistent test structure
Unicode character handling
