 ## How does Bootstrap's test suite work?
 
-Bootstrap uses [QUnit](https://qunitjs.com/), a powerful, easy-to-use JavaScript unit test framework. Each plugin has a file dedicated to its tests in `unit/<plugin-name>.js`.
+Bootstrap uses [QUnit](https://qunitjs.com/) and [Sinon](http://sinonjs.org/). Each plugin has a file dedicated to its tests in `unit/<plugin-name>.js`.
 
 * `unit/` contains the unit test files for each Bootstrap plugin.
-* `vendor/` contains third-party testing-related code (QUnit and jQuery).
+* `vendor/` contains third-party testing-related code (QUnit, jQuery and Sinon).
 * `visual/` contains "visual" tests which are run interactively in real browsers and require manual verification by humans.
 
 To run the unit test suite via [Karma](http://karma-runner.github.io/), run `npm run js-test`.
