Debug

From How to debug your code with JsTestDriver:

• Start server and capture the browser which you would like to debug

• Run the failing test using:

  java -jar JsTestDriver.jar --tests MyTestCase.testIWantToDebug
  

  This should load all of your JavaScript source files into the Browser

• Open your debugger and you should see all of your source files present in your debugger.

• Open the source file and place a breakpoint anywhere you wish.

• Rerun the test using the previous command. The debugger should stop at your breakpoint where you should have full access all of your code, variables, and DOM.
