Testing Dojo 1.x apps in Intern 3.x

Question

I'm trying to write some unit tests for code that uses Dojo 1.10.4 and so far I haven't had any success. I've tried lots of things, but I'm currently trying to use Intern 3.0.5. Here's what I've got in intern.js at the moment:

define({
  capabilities: { 'browserstack.selenium_version': '2.45.0' },
  environments: [ { browserName: 'firefox', version: '40', platform: ['WINDOWS'] } ],
  maxConcurrency: 2,
  tunnel: 'NullTunnel',
  //loaders: { 'host-browser': 'dojo/dojo.js' },
  loaderOptions: {
    packages: [
      { name: 'app', location: 'src' },
      { name: 'dojo', location: 'dojo' },
      { name: 'dijit', location: 'dijit' }
    ],

    map: {
      '*': {
        'dojo': 'dojo',
      },
      'intern': {
        'dojo': 'node_modules/intern/node_modules/dojo'
      }
    }
  },
  suites: ['tests/unit/ButtonTests'],
  excludeInstrumentation: true,
  useSauceConnect: false,
  proxyPort: 9000,
  proxyUrl: 'http://localhost:9000/'
});

dojoConfig = {
  has: { 'dojo-undef-api': true }
};

My hope is that I can let Intern use the Dojo 2 loader that it ships with, but then point my code at Dojo 1.10.4, so I set up a map in loaderOptions to take care of that. Unfortunately, my code doesn't seem to be picking up the right copy and I'm getting this error:

I also tried making Intern use the loader that comes with Dojo 1.10 instead of the one it ships with, which is commented out in the config I pasted above. When I do that, I get this error:

I was also getting this error yesterday, but I can't remember exactly how I did it! I was trying to use PhantomJS, so that might have done it:

Error: Repeated sequence for session 08ee5fa0-67a6-11e5-9d1c-49f2f4677a77: 0 last 0 cur

  at <_stream_readable.js:908:16>
  at process._tickCallback  <node.js:355:11>

On a side note, should I be able to set dojoConfig at the end of intern.js like I'm doing above? I'd like to enable dojo-undef-api.

Any help would be greatly appreciated!

The Dojo Boilerplate includes an Intern configuration for Dojo applications, that can be adapted for use in your project.
