Bootstrap Testing: Unit Tests with Jest and Minitest

The Bootstrap repository demonstrates a comprehensive testing approach focused on unit testing using Jest and Minitest frameworks. The test suite encompasses critical UI component validations, including focus management, template generation, DOM operations, and interactive elements like carousels and scrollspy functionality. The tests effectively verify Bootstrap's core utilities and components through detailed assertions and behavior checks. Qodo Tests Hub provides developers with an organized view into Bootstrap's testing patterns, making it easier to understand how a major frontend framework implements testing best practices. Through the platform, developers can explore real test implementations for complex UI scenarios, analyze testing strategies for different components, and learn practical approaches to frontend testing that can be applied to their own projects.
