FakeXMLHttpRequest 

This library provide a fake XMLHttpRequest object for testing browser-based
libraries. It is partially extracted (and in many places simplified) from
Sinon.JS and attempts to match the behavior of
XMLHttpRequest specification.

Why not just use Sinon.JS?

Sinon includes much more than _just_ a fake XHR object which is useful in
situations where you may not need mocks, spies, stubs, or fake servers.

How to use it

In addition to matching the native XMLHttpRequest's API, FakeXMLHttpRequest
adds a respond function that takes three arguments: a HTTP response status
number, a headers object, and a text response body:

``javascript
// simulate successful response
import FakeXMLHttpRequest from "fake-xml-http-request";

let xhr = new FakeXMLHttpRequest();
xhr.respond(200, {"Content-Type": "application/json"}, '{"key":"value"}');
xhr.status; // 200
xhr.statusText; // "OK"
xhr.responseText; // '{"key":"value"}'

// simulate failed response
xhr = new FakeXMLHttpRequest();
xhr.abort();
`

There is no mechanism for swapping the native XMLHttpRequest or for
recording, finding, or playing back requests. Libraries using FakeXMLHttpRequest
should provide this behavior.

Testing

Tests are written in QUnit and run through the
Karma test runner.

Run with:

`
karma start
``
