Utilities for testing React applications with Mocha. Includes enzyme, jsdom, and react-addons-test-utils.

Usage

1. Install with npm.

   npm install underdog-mocha-react --save

2. Import and use in your test.

   import React from 'react';
   import assert from 'assert';
   import reactUtils from 'underdog-mocha-react';
   
   describe('A sufficiently thorough test', function () {
     // Returns a helper method for rendering elements with enzyme.mount, render().
     // Also creates a fake dom with jsdom, accessible from global.window.
     const {render, simulateDOMEvent} = reactUtils();
   
     it('confirms all the things', function () {
       // Render component render() to get an Enzyme wrapper via enzyme.mount().
       const wrapper = render(
         <a href="/test">Hey there</a>
       );
   
       // You also get a fake window object for your tests.
       // This is useful for simulating events with wrapper.find('...').simulate().
       assert.notEqual(typeof window, 'undefined');
   
       // Test how your component reacts to DOM events with simulateDOMEvent()
       simulateDOMEvent(document, 'keydown', {
         keyCode: 27
       });
     });
   });
