Grunt Karma Backbone not defined - backbone.js

Question

I believe this is similar to the following issue, but I cannot locate where the configuration breakdown had occurred. https://github.com/karma-runner/grunt-karma/issues/52
command prompt error
Connected on socket (censored) with id (censored)
Chrome 45.0.2454 (Windows 8.1.x) ERROR
Uncaught ReferenceError: Backbone not defined at c:/path/base/dir/backbone-validation/dist/backbone-validation-min.js:8
standard backbone-validation.js install
Backbone.Validation = (function(_) { ... })
Below is the configuration definitions with relative paths.
package.json
dependencies:{},
devDependencies: {
grunt: '^0.4.5',
grunt-karma: '^0.12.1',
karma-requirejs: '0.2.2'
requirejs: '^2.1.20'
...
}
test config file
require.config({
baseUrl: 'path',
paths: {
'jquery': '../dir/jquery/dist/jquery',
'backbone': '../dir/backbone/backbone',
'underscore': '../dir/underscore/underscore',
'backbone.validation': '../dir/backbone/backbone-validation/dist/backbone-validation'
},
shim: {
'backbone': {
deps: ['underscore','jquery'],
exports: 'Backbone'
},
'backbone.validation': {
deps: ['backbone'],
exports: 'Backbone'
}
}
...
})
karma config file
module.exports = function(c) {
c.set({
basePath: 'base',
frameworks: ['requirejs', 'jasmine'],
files: [
{pattern: 'karma.conf.js'},
{pattern: 'path/dir/jquery/dist/*.js', included: true, served: true},
{pattern: 'path/dir/underscore/**/*.js', included: true, served: true},
{pattern: 'path/dir/backbone/*.js', included: true, served: true},
{pattern: 'path/dir/**/*.js', included: true, served: true},
{pattern: 'path/js-scripts/**/*.js', included: true, served: true},
{pattern: 'test-files/**/*.js'}
]
...
})
}
When opening the developer console in the browser, I can see the underscore, jquery, and backbone-validation files (among a few others not specified here) as included in the "sources" tab, but the "backbone" definition is missing. Can anyone point me in the direction of where my configuration might be incorrect?
// EDIT 9/23
I've also tried permutations of "backbone-validation" and "backboneValidation".
// EDIT Sept.23.11:54
karma.conf.js updated to have included/served values based on the thread http://stackoverflow.com/questions/27050180/karmajs-jasmine-requirejs-etc-how-to-use-require-for-testing-modules?rq=1 but now I receive the error requirejs mismatched define. define(['pkg','dep'], function(a,b) {...}) That looks like the correct syntax to me.
