Testing ViewComponent Property Initialization in Brakeman

This test file validates the basic functionality of a ViewComponent class implementation in a Rails 6 application. It tests the initialization and property handling of a custom view component, ensuring proper inheritance and state management.

Test Coverage Overview

The test suite verifies the core functionality of the TestViewComponent class that inherits from ViewComponent::Base. Coverage includes:

Component initialization with property injection
Instance variable assignment
Base class inheritance verification
Component state management

Implementation Analysis

The testing approach focuses on unit testing the ViewComponent implementation, utilizing Ruby’s class definition patterns. The test validates the component’s constructor behavior and property handling, following Rails 6 view component architectural patterns.

Key implementation aspects include class inheritance structure and instance variable management through constructor injection.

Technical Details

Testing infrastructure includes:

Ruby test framework integration
ViewComponent library dependencies
Rails 6 testing environment
Component initialization test helpers

Best Practices Demonstrated

The test implementation showcases several testing best practices including proper class inheritance, clean constructor implementation, and explicit property management. The code demonstrates clear separation of concerns and follows Ruby naming conventions and ViewComponent patterns.

Single responsibility principle adherence
Clear initialization parameter handling
Proper base class extension
