Unit Testing Browserify Project with Karma + Jasmine

I am trying to setup unit testing for a JavaScript plugin that is based on AngularJS. The plugin is bundled with Browserify via Gulp. It depends on external libraries that are injected with wiredep and gulp-inject from the bower_components folder. This is all working beautifully in the generated bundle, but if I try to run a Karma unit test via gulp, I get the following error:
Uncaught TypeError: angular.module is not a function at /tmp/94dbea5947f4758ab1ee6935e2f4b3f1.browserify:365 <- app/js/services/index.js:9:0
In this file, angular is loaded with var angular = require('angular');, and a console.log(angular) gives an empty object.
My karma.conf.js:
'use strict';
const istanbul = require('browserify-istanbul');
const isparta = require('isparta');
const mainBowerFiles = require('main-bower-files');
const karmaBaseConfig = {
basePath: '../',
frameworks: ['jasmine', 'browserify'],
preprocessors: {
'app/js/**/*.js': ['browserify', 'coverage'],
'**/*.html': ['ng-html2js']
},
browserify: {
debug: true,

[["babelify", {"ignore": "/\/bower_components\//"}]],
'browserify-ngannotate',

})
]

}).concat([

'app/js/main.js',
// 3rd-party resources
'node_modules/angular-mocks/angular-mocks.js',
// test files
'test/unit/**/*.js'
]),
exclude: [],
reporters: ['progress', 'coverage'],
port: 9876,
colors: true,
autoWatch: false,
browsers: ['Chrome'],
singleRun: true
};
const customLaunchers = {
chrome: {
base: 'SauceLabs',
browserName: 'chrome'
}
};
const ciAdditions = {
sauceLabs: {
testName: 'Karma Unit Tests',
startConnect: false,
build: process.env.TRAVIS_BUILD_NUMBER,
tunnelIdentifier: process.env.TRAVIS_JOB_NUMBER
},
browsers: Object.keys(customLaunchers),
customLaunchers: customLaunchers,
reporters: ['progress', 'coverage', 'saucelabs']
};
module.exports = function (config) {
const isCI = process.env.CI;
config.set(isCI ? Object.assign(karmaBaseConfig, ciAdditions) : karmaBaseConfig);
};
All main application files are located under app/, bower files in bower_components/, node modules in node_modules/ and test specs in test/unit/.
It is based on this boilerplate: https://github.com/jakemmarsh/angularjs-gulp-browserify-boilerplate.
The error occurs just after Karma has launched Chrome, but before any unit test are executed (I checked with console.log in the unit test).
Any help would be greatly appreciated.

Finally solved it.
unit.js (gulp unit task):
'use strict';
import config from '../config';
import path from 'path';
import gulp from 'gulp';
import {Server} from 'karma';
gulp.task('unit', ['copy-bower-components',
'styles',
'images',
'fonts',
'api',
'views',
'browserify',
'inject'
], function (done) {
new Server({
configFile: path.resolve(__dirname, '../..', config.test.karma),
singleRun: true
}, function (exitCode) {
console.log('Karma has exited with ' + exitCode);
done();
}).start();
});
The key here was to run browserify before the unit tests are started. karma.conf.js:

sinon is undefined in testing plugin (parse-mock)

I am attempting to use Karma to run a testing framework over AngularJS. Our application uses Parse.com's NoSQL database, and we'd like to test our code without calling it, so I'm trying to use parse-mock to do it.
However, I'm pretty sure I'm setting something up wrong, because I've managed to get everything to the point where the only issue is that "sinon" is undefined in the plugin parse-mock.
Here is the karma.conf.js file:
// Karma configuration
// Generated on Fri Nov 13 2015 13:23:29 GMT-0600 (CST)
module.exports = function(config) {
config.set({

browsers: ['Chrome'],
// Continuous Integration mode
// if true, Karma captures browsers, runs the tests and exits
singleRun: false
})
}
Here is the test-main.js file (requirejs configuration):
var allTestFiles = [];
var TEST_REGEXP = /(spec|test)\.js$/i;
// Get a list of all the test files to include
Object.keys(window.__karma__.files).forEach(function(file) {
if (TEST_REGEXP.test(file)) {
// Normalize paths to RequireJS module names.
// If you require sub-dependencies of test files to be loaded as-is (requiring file extension)
// then do not normalize the paths
var normalizedTestModule = file.replace(/^\/base\/|\.js$/g, '');
allTestFiles.push(normalizedTestModule);
}
});
require.config({
// Karma serves files under /base, which is the basePath from your config file
baseUrl: '/base',
paths: {
'sinon': 'node_modules/sinon/lib/sinon.js',
//'parse': 'app/js/parse-1.5.0.min.js'
},
use: {
'sinon': {
attach: 'sinon'
}
},
// dynamically load all test files
deps: allTestFiles,
// we have to kickoff jasmine, as it is asynchronous
callback: window.__karma__.start
});
And finally, the relevant line from the parse-mock plugin:
sinon = (typeof window !== "undefined" ? window.sinon : typeof global !== "undefined" ? global.sinon : null)
I checked, both window.sinon and global.sinon are undefined, and I have no idea why.

Jasmine Tests give error "Uncaught ReferenceError: require is not defined"

I am trying to run Jasmine tests with Karma on my React site. My tests were working before, and I'm not sure what has changed, but now I get the error:
Uncaught ReferenceError: require is not defined
for Chrome and PhantomJS and Firefox give me similar errors. Please let me know if more info would be helpful. I have found a lot of similar questions on the web, but nothing that fixes the problem.
You can see the test file below and the full project is on my github repo.
Thanks in advance!
My test file looks like this:
var React = require('react/addons');
var Story = require('../../app/js/components/story.jsx');
var TestUtils = React.addons.TestUtils;
var testUtilsAdditions = require('react-testutils-additions');
describe('Story component', function () {
var component;
beforeEach(function () {
var element = React.createElement(Story);
element.props.data = {
storyTitle: 'front end test title',
author : 'front end author',
storyText : 'front end story text'
};
component = TestUtils.renderIntoDocument(element);
});
it('should display a story', function () {
expect(component.props.data).toBeDefined();
expect(component.props.data.storyTitle).toBeDefined();
expect(component.props.data.storyTitle).toBe('front end test title');
expect(component.props.data.author).toBe('front end author');
expect(component.props.data.storyText).toBe('front end story text');
});
});

You should have require configured in your karma.conf file such as example:
module.exports = function(config){
config.set({
frameworks: ['jasmine'],
plugins : [
'karma-chrome-launcher',
'karma-firefox-launcher',
'karma-script-launcher',
'karma-phantomjs-launcher',
'karma-jasmine',
'karma-requirejs'
],
files : [
'node_modules/requirejs/require.js',
'node_modules/karma-requirejs/lib/adapter.js',
'app/js/test-main.js',
{pattern: 'app/lib/**/*.js', included: false},
{pattern: 'app/js/**/*.js', included: false},
{pattern: 'app/js/views/**/*Test.js', included: false}
],
browsers: ['PhantomJS']
});
};

Grunt Karma Hangs Forever

I have 2 configurations I want to test, wrapper and app. For technical reasons, these need to be separated configurations. When I run either, "grunt karma:app" or "grunt karma:wrapper" I get the following:
Running "karma:wrapper" (karma) task
INFO [karma]: Karma v0.12.32 server started at http://localhost:9876/
Which hangs indefinitely. Bellow is my grunt configuration:
karma: {
app: {
unit: {
configFile: 'test/karma.app.conf.js',
singleRun: true
}
},
wrapper: {
unit: {
configFile: 'test/karma.wrapper.conf.js',
singleRun: true
}
}
}

Karma Jasmine Angular not defined

I am trying to learn how to use angular and karma to test angularjs and nodejs. I have used Noesavy's youtube videos to learn how to set up karma and jasmine. His examples work fine but when I try to use jasmine and karma with my own code I get angular undefined. My code is posted below:
passwordScript.js
angular.module('myApp', []).controller('S',
['$scope',
function($scope){
$scope.checkPass = function(insert_password, confirm_password){
if(insert_password == confirm_password){
$scope.passBoole = true;
} else {
$scope.passBoole = false;
}
};
}]);
checkPassSpec
describe("Password Controller", function(){
var $rootScope,
$scope,
controller;
beforeEach(function(){
module('myApp');
inject(function($injector){
$rootScope = $injector.get('$rootScope');
$scope = $rootScope.$new();
controller = $injector.get('$controller')("S", {$scope: $scope});
});
});
describe('Password check', function(){
it('should set $scope.passBoole top false', function(){
checkPass("bob", "tom");
expect($scope.passBoole).toEqual(false);
})
it('should set scope.passBoole to true', function(){
checkPass("bob", "bob");

I really have no idea why this is happening and any help would be greatly appreciated.
