React Testing Library

Definition

RTL is a lightweight solution for testing React components. Its primary guiding principle is: 'The more your tests resemble the way your software is used, the more confidence they can give you.'

Explain Like I'm New

Instead of testing the internal state variables of a component, RTL forces you to test what the user actually sees on the screen (like finding a button by its text).
