SEATTLE — Microsoft on Thursday launched BrowserSwarm, an open-source tool for testing JavaScript frameworks and libraries across browsers and devices.

Well-built interoperable frameworks are the foundation of the modern web, but testing them  something many developers don’t always have the resources to do.

Developers can point BrowserSwarmat the code’s GitHub repository, and the system then uses the popular QUnit JavaScript Unit Testing framework on top of a web app cloud testing platform built by SauceLabs

If you don’t write your own frameworks and libraries, that's OK. BrowserSwarm allows you to see the test results for many popular ones like Prototype, BackBone.js and Jquery to ensure that apps will run smoothly across a wide variety of browsers.

For developers who upload their own code, BrowserSwarm creates a basic table with grading — pass or fail — scored for all the popular browsers. BrowserSwarm also offers detailed job reports.
