Getting "Mismatched anonymous define() module..." when I try running tests

I am trying to configure my karma jasmine unit testing with requirejs. But each time i run it, i am getting the below error:

Chrome 34.0.1847 (Mac OS X 10.9.2) ERROR
Uncaught Error: Mismatched anonymous define() module: function (angular){

 describe('Unit: Testing RequireJS', function(){
  var ctrl;
  var scope;
  var rootScope;

  beforeEach(angular.mock.module('wsaApp'));

  beforeEach(angular.mock...<omitted>...ch

Below are differenr file: spec file:

define(['angular'], function(angular){

    scope = $rootScope.$new();
    rootScope = $rootScope;
}));
