Ajax Spy

It provides a simple interface for hijacking AJAX requests. It spies AJAX requests and it sends them to the desired server. It could be useful for testing a web app backed by a REST service, using another endpoint for the service, without changing the code.

Usage

You should import the ajaxSpy.js file in your browser/headless browser. Create an AjaxSpy object using the constructor. Then specify all the requests pattern that should be redirected to another URL, for example of the test server.

var ajaxSpy = new AjaxSpy("127.0.0.1", 1337);
ajaxSpy.setup();
ajaxSpy.spy("POST", /\w+login/, 'user=demo@example.com&pass=demo');
ajaxSpy.spy("GET", /\w+events/);

// Now AJAX requests that match the specified pattern will be redirected to the AjaxSpy object address.

// Run some tests.

ajaxSpy.tearDown();

AjaxSpy could be useful to write tests without modifying anything in the application code during tests. In order to be effective, requests to server must rely on AJAX protocol, for example as in a single page application.
