angular-mock testing in Karma+Mocha can't find module - angularjs

Question

I'm learning AJS unit testing, with RequireJS, Karma, Mocha, Chai and angular-mocks. I've had some luck with the first four, but need to get into "real" testing and can't get angular-mocks to work. There's a lot going on, so I'll be as succinct as possible.
test/karma.conf.js
module.exports = function (config) {
config.set({
// requirejs may need to be listed before other modules (see https://github.com/princed/karma-chai-plugins#limited-requirejs-support)
frameworks: ["requirejs", "mocha", "chai"],
files: [
// load the RequireJS config files first
{pattern: "client/app/require-shared.js", watched: false},
{pattern: "test/require-test.js", watched: false},
// set included to false for files to be loaded via RequireJS
{pattern: "client/**/*.js", included: false },
{pattern: "bower_components/**/*.js", included: false, watched: false},
// Mocha stuff
{pattern: "test/unit/mocha.conf.js", watched: false},
// test files
{pattern: "test/unit/**/pageSelectorTest.js", included: false }
],
exclude: [
"client/app/bootstrap.js",
"client/app/require-main.js",
"*.conf.js"
],
reporters: ["spec"],
// enable / disable watching file and executing tests whenever any file changes
autoWatch: false,
browsers: [
"PhantomJS"
],
singleRun: true
});
};
test/unit/mocha.conf.js
window.mocha.setup({
ui: "tdd"
});
test/unit/MyTest.js
define([
"angular-mocks"
,"app"
], function () {
"use strict";
var MODULE_NAME = "PageSelector";
var assert = chai.assert;
suite("Unit testing " + MODULE_NAME, function() {
suite(MODULE_NAME + " module", function () {
var appModule;
setup(function () {
// "ng" and "ngMock" modules automatically loaded
appModule = angular.mock.module(MODULE_NAME);
console.log(appModule);
});
// setup(function () {
// angular.mock.inject(function () {
//
// });
// });
test("should exist", function () {
assert.isDefined(appModule, "module exists");
});
}); // end module tests
});
});
I'll skip posting all the RequireJS config. I'm pretty sure I'm getting angular and angular-mocks, because I've worked through those errors already.
My Gruntfile simply has an option to load karma.conf.js. The output of grunt karma is:

If I change angular.mock.module(MODULE_NAME); to angular.module(MODULE_NAME);, the assert works. What am I missing? (I apologize if there isn't enough info above. I can post more, as needed.)

Answer 1

I dug into angular-mocks.js. module is just a set-up for inject. On its own, it doesn't actually load a module, like angular.module does. I was using it unnecessarily for "module-level" testing, where angular.module is appropriate.
When getting in to actual controller/directive/etc. testing, I'll need the module+inject pair.
