mocha/test/browser/index.html doesn’t work properly in Firefox 10

[gamtiq]

Hello,

For the unknown reason first browser tests from mocha/test/browser/index.html fail in Firefox 10.0.2.
All tests pass as expected in Chrome.

Best wishes,
Denis

haha, the stack traces are so bad in FF.. i'll look into it

it's saying there's a "location" variable leaking haha, seems like something the host must be doing, we use window.location once but that's it

looks like FF exposes the 'location" global variable between the jquery ready event and the window.onload event. i.e. if I move mocha.run() from jquery.ready to window load the error goes away. (using FF 11)
P.S. I also had a problem with a third party lib "syn.js" exposing a global which I used mocha.run().globals(['__synthTest']) to remove the error. But what is interesting is that Chrome reports it as a leaked global while Firefox does not. I think its also a timing issue of when globals are introduced. I got rid of my global issues by doing the following:

$(window).load(function() {
  return setTimeout((function() {return mocha.run();}), 1);
});

hmm interesting, we could list location as a known global, not the greatest solution but at least we wont have a lot of confused people
