Karma: Executed 0 of 0 Error - requirejs

Question

I think I have everything set up properly. I followed the specs of the Karma Tutorial for RequireJS, but everything I've tried seems to result in the same error.
It appears that my test-main.js file is being loaded since a console.log() will fire. However, in the Object.keys loop, the files will get listed, but TEST_REGEXP fails so the allTestFiles ends up being an empty array. I'm sure it's something silly, but it's created just like the Tutorial - with the exception of using node_modules for jquery, require, underscore.
My test-main.js file:
var allTestFiles = [];
var TEST_REGEXP = /test\.js$/;
var pathToModule = function(path) {
return path.replace(/^\/base\//, '').replace(/\.js$/, '');
};
Object.keys(window.__karma__.files).forEach(function(file)
{
if(TEST_REGEXP.test(file))
{
// Normalize paths to RequireJS module names
allTestFiles.push(pathToModule(file));
}
});
if(console) console.log(allTestFiles);
require.config(
{
// Karma serves files under /base, which is the basePath from the config file
baseUrl: '/base/src',
paths:
{
'jquery':'../node_modules/jquery/dist/jquery',
'underscore':'../node_modules/underscore/underscore-min'
},
shim:
{
'underscore': { exports: '_' }
},
// dynamically load all test files
deps: allTestFiles,
// kick off jasmine, as it is asynchronous
callback: window.__karma__.start
});
My karma.conf.js file:
module.exports = function(config) {
config.set({
// base path that will be used to resolve all patterns (eg. files, exclude)
basePath: '',
// frameworks to use
// available frameworks: https://npmjs.org/browse/keyword/karma-adapter

{pattern: 'src/*.js', included: false},
{pattern: 'test/**/*Spec.js', included: false}
],
// list of files to exclude

});

I came across a solution to the problem.
I ended up changing my test-main.js file above the require.config section to this:
// Karma RequireJS configuration
var tests = [];
for (var file in window.__karma__.files) {
if (/Spec\.js$/.test(file)) {
tests.push(file);
}
}
If I simply changed TEST_REGEXP to /Spec\.js$/ I ended up getting a timestamp error. I don't know why. More interesting is why following the guide produces errors. But it is all working now.
