回答1:

you are missing chai lib path files array in which is dependency to mocha.include it.

files : [
        'node_modules/jquery/**/*.js',
          'lib/angular/angular.js',
          'lib/angular/angular-*.js',
          '../test/lib/angular-mocks.js',
          '../test/lib/sinon-1.15.0.js',
          '../test/chai/chai.js',
          'js/**/*.js',
          '../test/unit/**/*.js',
          '**/*.html'
        ],

I came across a similar situation just with Jasmine. I'd like to introduce my solution.

Try it what is written in the error message. There is a link to a website: http://requirejs.org/docs/errors.html#notloaded

//If this code is not in a define call,
//DO NOT use require('foo'), but use the async
//callback version:
require(['foo'], function (foo) {
    //foo is now loaded.
});

My case written for Jasmine in Coffee script looks like this:

sinon = require(['sinon', 'jasmine-sinon']) (foo)->

Now I can use sinon as an object in my unit test and can also follow the documentation of sinon, as well as jasmin-sinon.
