Running on serverside about qunit

[benjaminplee]

It looks to be a problem w/ marshaling real java objects to java. I am looking into this.

[benjaminplee]

Issue is rooted in how QUnit handles the QUnit test which includes a setTimeout in the actual test code. QUnit attempts to build an error message using the error object by calling jsDump. Rhino's reference error includes a reference to the internal Rhino error that was thrown which has a reference to what looks like a byte array. When jsDump is called again on this byte array the error above is thrown.

Not sure yet how to solve without adding Rhino specific code to QUnit.

Obvious solutions is to make the QUnit test only execute if setTimeout is defined, but this doesn't solve the bigger issue of how jsdump traverses errors thrown in rhino.

A better solution might be enhancing the "error" parser in jsdump to output the error's message, line number ets, and have the calling code include the type value of "error" so that jsdump doesn't need to try and determine it internally.

Resolved on my consistent-checks branch. Pull request sent. #59

Are we sure that this problem is fixed for setInterval? I'm getting the following message given the latest code on the master branch:

InternalError: Java class "[B" has no public instance field or method named "setInterval". (http://localhost:8080/js/com/jquery/qunit/25e4489/qunit-25e4489.js#1177)

@huntc: Can you provide a testcase? Running the QUnit testsuite with Rhino works fine.

[huntc]

Hey there - I'm sorry, I've got caught up in stuff... I'll try putting something together v. soon.

[jzaefferer]

@huntc: Still there? :-)

I am receiving this same error while using QUnit and Sinon to test my Backbone.js application.

My Test

module('BackboneView', {
  setup:function(){
    this.myModel = new Backbone.Model;
    this.bindSpy = sinon.spy(this.myModel, "bind");
    this.myView = new Backbone.View({model:this.myModel});
  },
  teardown:function(){
    this.myModel.bind.restore();
  }
});

test('Binds to a change of the foo attribute', function() {
  ok(this.bindSpy.calledWith("change:foo", this.myView.render));
});

The Implementation

window.myView = Backbone.View.extend({
  initialize: function(){
    _.bindAll(this, 'render');
    this.model.bind("change:foo", this.render);
  },
});

When I run my ant build which uses Rhino I get a stack trace like this:

But, I am using QUnit Test Runner

I'm wondering if there is a version of QUnit that Qunit Test Runner is bundling that is out of date.

[huntc]

Hi Clayton,

I think you have contacted the wrong project. My project is:

http://js-testrunner.codehaus.org/

JS Test Runner does not impose any specific version of QUnit on you.

Kind regards,
Christopher

[clayton]

I was just commenting to provide an example of the error that someone had mentioned above as possibly being fixed. It sounded like there was some confusion as to if the issue was actually fixed.

[huntc]

My apologies for the confusion. Its been a long day!

[jzaefferer]

Seems to work fine. Will reopen if someone provides their own, failing, runner, instead of just the output.
