QUnit is a powerful and easy-to-use JavaScript unit testing framework

Security
These libraries will only be used for internal testing only and will not be shipped.  It will not have any security impact on chrome.

Why QUnit?
1. Open source and good community support
2. Easy to configure which makes it easy to integrate with the browser test framework
3. Easy code coverage support with blanket.js
4. Its TDD style is consistent with our C++ GTest.
5. Support DOM interactions (unlike the JS2Gtest framework)

+Description:
+QUnit is a powerful, easy-to-use, JavaScript unit testing framework. It's used
+by the jQuery project to test its code and plugins but is capable of testing any
+generic JavaScript code (and even capable of testing JavaScript code on the
+server-side).
+
+QUnit is especially useful for regression testing: Whenever a bug is reported,
+write a test that asserts the existence of that particular bug. Then fix it and
+commit both. Every time you work on the code again, run the tests. If the bug
+comes up again - a regression - you'll spot it immediately and know how to fix
+it, because you know what code you just changed.
+
+Having good unit test coverage makes safe refactoring easy and cheap. You can
+run the tests after each small refactoring step and always know what change
+broke something.
+
+QUnit is similar to other unit testing frameworks like JUnit, but makes use of
+the features JavaScript provides and helps with testing code in the browser,
+e.g. with its stop/start facilities for testing asynchronous code.
+
+It is currently used by the chrome remote desktop team for JavaScript unit
+testing.
