Last active September 10, 2015 13:31
Testing react components with Mocha and NodeJS
// React decides if it has a DOM on loading, so if we always need to
// initialise JSDOM before loading it.
var testdom = require('testdom');
testdom('<html><body></body></html>');
// But React hates you even more than that... it caches the rendered component
// in the DOM and if the same type of component with the same key is rendered at
// into the same element, then it uses the cached instance, not the just rendered
// instance. Even if the props are different. So the instance being tested will
// not be exercised.

Refactoring to Asynchronous in JavaScript

Note: the latest version of this document is at http://natpryce.com/articles/000812.html

Here's some code that gets and uses a value from a synchronous call or built in data structure:

function to_be_refactored() {
    var x;
    ...
 x = get_x();
