These projects test on Sauce

We use Yeti with Sauce Labs to run over 25,000 tests for every commit to YUI.



Are you a framework? Use Sauce to test your project for free with Open Sauce »

Here's how it works

Easily run your Jasmine, QUnit, YUI Test, or Mocha tests on Sauce using Grunt, Yeti, Karma, Mocha Sauce, or Intern.

Or, use whichever tools you prefer with our simple REST API. Here's an example request:

curl -X POST$SAUCE_USERNAME/js-tests \
    -d platforms='[["Windows 8", "internet explorer", "10"],
                   ["OS X 10.8", "safari", "6"]]' \
    -d url="" \
    -d framework=jasmine

See our complete REST API documentation for more info.
