Important note: the master branch hosts the development version of CasperJS, which is now pretty stable and should be the right version to use if you ask me.

Use the 1.0 branch if you want to keep in sync with the stable old version, or use tagged versions.

Currently, available documentation is:

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

Travis-CI build status:

• master branch
• 1.0 tests unfortunately have to be run manually using the casperjs selftest command

CasperJS is a navigation scripting & testing utility for PhantomJS and SlimerJS. 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!

Sample test to see if some dropdown can be opened:

    casper.start('http://twitter.github.com/bootstrap/javascript.html#dropdowns', function() {
        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');
        });
    }).run(function() {
        test.done();
    });
});
