Important note: the master branch hosts the development version of CasperJS, and may be rather instable from time to time. Use the 1.0 branch if you want to keep in sync with the stable version, or use tagged versions.

Currently, available documentation is:

• hosted on casperjs.org for the 1.0 branch
• hosted on docs.casperjs.org for the development branch

Travis-CI build statuses:

• 
  1.0 branch
• 
  master branch

CasperJS is a navigation scripting & testing utility for PhantomJS. It eases the process of defining a full navigation scenario and provides useful high-level functions, methods & syntaxic sugar for doing common tasks such as:

• defining & ordering navigation steps
• filling forms
• clicking links
• capturing screenshots of a page (or an area)
• making assertions on remote DOM
• logging & events
• downloading base64 encoded resources, even binary ones
• catching errors and react accordingly
• writing functional test suites, exporting results as JUnit XML (xUnit)

Browse the sample examples repository. Don't hesitate to pull request for any cool example of yours as well!

        test.assertExists('#navbar-example');
        this.click('#dropdowns .nav-pills .dropdown:last-of-type a.dropdown-toggle');
        this.waitUntilVisible('#dropdowns .nav-pills .open', function() {
            test.pass('Dropdown is open');
        });
