Testing ViewComponent Inheritance Patterns in brakeman

This test file validates the implementation of a ViewComponent with fully qualified ancestor class in a Rails 6 application. It focuses on proper class inheritance and component initialization, ensuring components are correctly structured and initialized with properties.

Test Coverage Overview

The test suite verifies the proper inheritance from ViewComponent::Base and initialization handling for view components. Key functionality includes:

Component class definition with explicit namespace resolution
Property initialization through constructor
Base class inheritance verification

Implementation Analysis

The testing approach focuses on component architecture and initialization patterns in Rails 6. It implements the ViewComponent pattern with explicit namespace qualification (::ViewComponent::Base), ensuring proper inheritance chains and component instantiation.

The implementation demonstrates proper Ruby class definition and instance variable initialization practices.

Technical Details

Testing tools and configuration:

ViewComponent framework integration
Rails 6 test environment
Ruby class inheritance verification
Instance variable initialization testing

Best Practices Demonstrated

The test exemplifies several quality practices in component testing:

Explicit namespace resolution for clear dependency chains
Clean constructor implementation with single responsibility
Proper instance variable initialization
Clear inheritance structure
