It's a great thing that with Resharper 6 one can write qunit tests and run those with the integrated resharper test runner. However, I wonder if it is possible to set breakpoints in the tests and the code under test. The problem is, each time it opens the browser it uses a different randomized port number which means you can not just set breakpoints in the browser and rerun the tests by hitting F5. So I wonder, is it even possible somehow?
Unfortunately, it is not possible at the moment - see this request. What I suggest you do right now if you need debugging is to use QUnit canonically - create an HTML page, drop your JS libs, tests and QUnit into them, and put in the QUnit HTML elements to display the results. This way, you'll be able to set breakpoints in JS.
