AngularJS / Karma testing: beforeEach not executed

The reason your log message console.log("in beforeEach..."); is not being displayed is because it is not actually inside beforeEach, it is inside an anonymous function passed to a module(..) as an argument which is considered to be a module by angular-mocks. This module will be executed only when injection happens and at the same time you'll receive a log message in beforeEach..., but there is no any injection in your test, so it never happens. beforeEach fires anyway, you just didn't put console.log in the right place; it will work:

beforeEach(function () {  console.log("in beforeEach...");  module('userApp', function($provide) {    // Output messages    $provide.value('$log', console);  });});

Also it seems that you forgot to inject mocked $log into you test suite, your $log variable never gets any value, so it stays undefined as the error states.

describe('userApp', function(){   var $log;  beforeEach(function () {    console.log("in beforeEach...");    module('userApp', function($provide) {      // Output messages      $provide.value('$log', console);    });    // getting an instance of mocked service to use in a test suite    inject(function (_$log_) {      $log = _$log_;    });  });   it('should be able to log something', function(){     console.log("in it...");    $log.info("Using $log for logging...");  }); });
