Microsoft Collaborates on Cloud-Based Browser Testing Tool

BrowserSwarm tests all major JavaScript frameworks for errors.

Microsoft has partnered with several other  vendors to release BrowserSwarm, an open source tool for testing JavaScript frameworks across multiple browsers.

Redmond's Internet Explorer team announced BrowserSwarm today, outlining a typical problem JavaScript developers have in testing software across a host of browsers. Smaller shops and startups normally don't have the kind of resources available to test code against the plethora of browsers available, and most developers dislike testing, too.

BrowserSwarm aims to fix that problem. A free account is required. After signing up, a developer simply connects BrowserSwarm directly to their projects in GitHub. Following that, Sauce Labs' cloud automatically runs Unit Tests against the software, using QUnit.

Every major JavaScript framework is tested, including jQuery; jQuery mobile; dojo; MooTools; prototype; Modernizr; and Underscore.js. The results are presented in a window that shows passing rates on various browsers, including IE, Chrome, Safari, Firefox and Opera. In addition, multiple versions of the browsers are tested.

Along with the pass/fail scorecard, a job report displays the test cases that fail and why.

BrowserSwarm was a partnership between Microsoft, appendTo and Sauce Labs. It works in conjunction with modern.IE, a Web site optimization tool.

    How to Compute Disorder for Machine Learning Decision Trees Using C#

    Using a decision tree classifier from a machine learning library is often awkward because it usually must be customized and library decision trees have many complex supporting functions, says resident data scientist Dr. James McCaffrey, so when he needs a decision tree classifier, he always creates one from scratch. Here's how.
