unit testing - Why is my intern test failing with "document is not defined"

Question

I am new to Intern and struggling with trying to get a simple test to run in my environment. I was able to get the tutorial test to run but I've tried to set up a test where the test file is located inside my app directory hierarchy. The module being tested is located here:

sandbox/web/libs/ev/grids/FilterGrid.js

The test file is located here:

sandbox/web/libs/ev/tests/FilterGrid.js

My intern config file is located here:

sandbox/tests/intern.js

My loader and suites objects looks like this:

loader: {
    packages: [
        { name: 'dojo', location: 'web/libs/dojo' },
        { name: 'dijit', location: 'web/libs/dijit },
        { name: 'dgrid', location: 'web/libs/dgrid' },
        { name: 'put-selector', location: 'web/libs/put-selector' },
        { name: 'xstyle', location: 'web/libs/xstyle' },
        { name: 'ev', location: 'web/libs/ev' }
    ]
},
suites: ['ev/tests/FilterGrid'],

When the loader tries to load this, I get:

Defaulting to "console" reporter

Does the unit tests using Intern need a DOM document defined?? I also notice that Intern lists dojo2_core as it's dependency. So it's using unreleased code?

Any help with this would be appreciated!

It looks like you’re trying to load some code using the Node.js client that requires a browser environment. This won’t work. You should only load the ev/tests/FilterGrid test suite in a browser. You can do this by modifying your Intern configuration file to look something like this:

define([ 'intern/node_modules/dojo/has' ], function (has) {
  var suites = [];

  if (has('host-browser')) {
    suites.push('ev/tests/FilterGrid');
  }

  return {
    // ...your existing configuration...
    suites: suites,
    // ...
  };
});
