@testing-library/vue provides utilities for testing Vue components in a way that encourages good testing practices. It focuses on testing components from the user's perspective, querying for elements as a user would. By finding elements based on their rendered output rather than internal implementation details, tests become more resilient to refactoring and provide greater confidence in the component's functionality. This library facilitates writing tests that resemble actual user behavior, ensuring a more reliable and maintainable codebase.
