Testing Library
The @testing-library
family of packages helps you test UI components in a user-centric way.
You want to write maintainable tests that give you high confidence that your components are working for your users. As a part of this goal, you want your tests to avoid including implementation details so refactors of your components (changes to implementation but not functionality) don't break your tests and slow you and your team down.
Testing Library accomplish these goals so you can be confident your application will work when it gets to the end user.
