Goal​

Test the required user behavior to infer the correct implementation and create a maintainable test base for for UI Code.

React Testing Library​

React Testing Library is a lightweight solution to test your react components, it provides utility functions on top of react-dom, uses JSDOM to test your react components, by querying DOM nodes in a document similar to the way a user will find elements in the page/component which helps your test base give confidence in your UI code.
