Unit Testing

Project Name

JavaScript Unit Testing

Project Description

Use an existing unit testing framework (or create one) and demonstrate its use by writing a collection of unit tests that fully test a browser feature of your choosing. The framework will provide decent setup and teardown code that will enable the programmer to start the browser, run the tests, report pass/fail and shutdown the browser.
