What is React Testing Library and how does it differ from Enzyme? React Testing Library (RTL) and Enzyme are two popular testing utilities for React. Feature React Testing Library Enzyme Philosophy Tests behavior from the user's perspective Tests component internals and implementation Test Focus Interaction, rendering, and

ccessibility

Shallow rendering, component

state, and props

Testing Approach Encourages testing DOM

behavior and accessibility

Encourages testing component

internals and methods
Integration with

React

Built with React’s rendering

behavior in mind

Requires enzyme adapter for

different React versions

Recommendation More modern, encourages

better testing practices

Still used, but React Testing

Library is more popular

Key difference:

• React Testing Library focuses on testing the output of your components (UI

behavior), similar to how a user interacts with the app.

• Enzyme focuses more on testing the internal implementation (component state,

methods).
