 # Using Jest with Enzyme

+## Jest version 15 and up
+
+Starting with version 15, Jest [no longer mocks modules by default](https://facebook.github.io/jest/blog/2016/09/01/jest-15.html). Because of this, you no longer have to add _any_ special configuration for Jest to use it with Enzyme.
+
+Install Jest, and its Babel integrations, as recommended in the [Jest docs](https://facebook.github.io/jest/docs/getting-started.html). Install Enzyme. Then, simply require/import React, Enzyme functions, and your module at the top of a test file.
+
+```js
+import React from 'react';
+import { shallow, mount, render } from 'enzyme';
+
+import Foo from '../Foo';
+```
+
+You do **not** need to include Jest's own renderer, unless you want to use it _only_ for Jest snapshot testing.
