How can I set breakpoints in my qunit tests when using the Resharper test runner

Question

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?

Answer 1

An easier approach using Resharper and Visual studio.

Just put as your first line in the js file:

QUnit.moduleDone = function(){}

The Resharper test won't finish and you can refresh your page in browser as many times you want. You may put a breakpoint then and rerun the test by hitting F5 in browser.

Example:

At the very top of your page you should have:

• your references first
• QUnit.moduleDone = function() {};

like so:

/// <reference path="Scripts/jquery-ver**.min.js"/>
/// <reference path="Scripts/jquery-ui.min.js"/>
/// <reference path="your_test_file.js"/>

QUnit.moduleDone = function() {};

This works perfectly!)

In your browser - just hit F12 (open debugger window), set your breakpoints and refresh the page with F5))

Answer 2

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.

Answer 3

If you are using Firefox with the Firebug plugin, you can do this: add a debugger statement to your code where you want to break:

var x = 2;
debugger;
...

Set the Firebug option 'Active for all Web Pages' to true. In ReSharper options, Testing>JavaScript set Firefox as the browser to use (if it is not already your default).

Now Firebug debugger will break at the debugger statement.

PS I tried this with Chrome but couldn't get it to break. Anyone know how to do it?
