We can add accessibility testing to our jest unit tests with jest-axe which gives us:

• An easy way to automate accessibility auditing
• the flexibility to audit at any level of our code, as low as an element and as high as a component representing an entire page of our app
• A safety net for any accessibility regressions

Here we'll see how to use jest-axe with react-testing-library to render the components for jest-axe to audit for accessibility.

The React Testing Library is a very light-weight solution for testing React components. It provides light utility functions on top of react-dom and react-dom/test-utils, in a way that encourages better testing practices.
