Testing String Classification and Constant Resolution Helpers in ddollar/foreman

This test suite validates core helper functions in the Foreman library, specifically focusing on string manipulation and constant handling. The tests ensure proper functionality of classification and constantization methods that are essential for Ruby object manipulation and naming conventions.

Test Coverage Overview

The test suite provides comprehensive coverage of the Foreman::Helpers module’s string manipulation capabilities.

Key areas tested include:

String classification functionality for simple and hyphenated words
Constant resolution through string-to-constant conversion
Edge cases handling for nested class names

Implementation Analysis

The testing approach utilizes RSpec’s behavior-driven development patterns with focused unit tests. The implementation leverages RSpec’s subject helper and module extension to create an isolated test environment.

Technical patterns include:

Dynamic module creation for test isolation
Object extension with tested module
Clean test environment through proper teardown

Technical Details

Testing infrastructure includes:

RSpec as the primary testing framework
Module extension for mixin testing
Before/After hooks for test setup and cleanup
Dynamic constant management

Best Practices Demonstrated

The test suite exemplifies several testing best practices in Ruby.

Notable practices include:

Proper test isolation through dynamic module creation
Clean test environment management
Focused test cases with clear expectations
Effective use of RSpec’s subject helper
