New Post: Error: TypeError: 'null' is not an object (evaluating 'activeTestCase.timetaken = timetaken')

(Cross-posted from http://stackoverflow.com/questions/22819736/null-is-not-an-object-when-running-jasmine-tests-via-chutzpah.)

I'm beating my head against a wall running some Chutzpah tests. I have a web page (https://payboardbeta.azurewebsites.net/widget/v1.0/test/PayboardTests.html, if you're interested) that has my JS unit tests, written using Jasmine. The tests all pass if I run the page in a browser (whether on my machine or any other that I've tried), and they similarly all pass if I run them via Chutzpah on my local dev machine. However, they fail with the following error message if I run them via Chutzpah (chutzpah.console.exe https://payboardbeta.azurewebsites.net/widget/v1.0/test/PayboardTests.html) on my build server.

I should note again that exactly the same command-line works correctly on my dev box.

This is the test in question:

it('should should submit form even if server never resolves', function (done) {
    Payboard.Events.setSampleGroupId(80);
    Payboard.Events.setPercentToTrack(90);
    var event = {
        target: { submit: function () {
                done(); // <-- THIS IS WHERE IT FAILS
            } 
        },
        preventDefault: function () { }
    };
    Payboard.Events.onSubmit(event, 100);
    // server.respond(); ** Make sure we don't resolve
});

It fails somewhere down deep in the Jasmine stack while processing the done() call, i.e., not anywhere in my code. The failure is apparently in the jasmine dispatch() method, i.e., here:

function dispatch(method, args) {
  for (var i = 0; i < reporters.length; i++) {
    var reporter = reporters[i];
    if (reporter[method]) {
      reporter[method].apply(reporter, args); // <-- THIS IS WHERE IT FAILS
    }
  }
}

Normally I would troubleshoot these test failures in the browser's dev console. But they don't fail there, even on my build machine - they only fail when running via Chutzpah, and then only on my build machine. (And, I should note, very occasionally, the tests do run correctly, which points to some sort of timing error, but darned if I know what it is.)

Any suggestions for troubleshooting this?
