How to use jest with webpack?

Question

I use webpack to develop a React component. Here is a simple version of it:

\'use strict\';

require(\'./MyComponent.less\');

var React = require(\'react\')         


        

Answer 1

Webpack is a great tool, but I don't need to test it's behavior with my Jest unit tests, and adding a webpack build prior to running unit tests is only going to slow down the process. The text-book answer is to mock non-code dependencies using the "moduleNameMapper" option
