Can ajax requests be made without a web browser?

Currently, I am in the process of developing JavaScript tests using mocha and chutzpah, which means conducting all my tests without a browser. However, I have encountered an issue where all my AJAX calls are resulting in empty strings. Even when using the following code snippet:

$.ajax({
    url: "http://www.something.com/",
    //Ajax events
    async: false,
}).done(function(data) {
    test = data;
});

In this scenario, the 'test' variable remains empty. Despite trying various combinations of AJAX parameters such as async, type, dataType, and success, I still face the same problem.

Therefore, my inquiry is - can AJAX calls be successfully executed without a browser?

Answer №1

Upon further investigation, it appears that chutzpah is built on top of Phantom.js, meaning your tests are actually running within a Webkit browser environment, just without a graphical user interface.

Because the tests are executed within a browser, they are subject to all standard browser restrictions, such as the same-origin policy. This could potentially cause issues with ajax calls depending on how chutzpah handles loading test scripts.

If chutzpah loads your test page from the disk, the same-origin policy will always fail. To work around this, consider having chutzpah load your test page from a URL (even running a local test server on localhost can suffice).

Additionally, it is possible to disable security features in Phantom.js by using the command line parameter --web-security=false. While I am not sure about the specific implementation details in Mocha and chutzpah, exploring this option may offer a solution to any security-related issues.

Answer №2

My problem turned out to be a rather silly one. For some reason, the Ajax queries on the framework I was working with required the use of "www." in the URL. So instead of making a call to "google.com," I had to make a call to "www.google.com." It seemed that the redirection from non-www to www wasn't functioning properly.
