这打开了一个外部Chrome浏览器，显示Karma已连接。我为我的一个函数编写了一个简单的单元测试，它似乎根本没有运行任何测试
这是我的karma配置文件。

// Karma configuration
module.exports = function(config) {
 config.set({
// base path, that will be used to resolve files and exclude
basePath: '',

// testing framework to use (jasmine/mocha/qunit/...)

// list of files / patterns to load in the browser

  'spec/javascripts/**/*.js'

我的单元测试

describe('Unit: AddMedicalService',function(){

beforeEach(module('DoctiblePreTreatment'));
var ctrl, scope;

beforeEach(inject(function($controller,$rootScope){
scope = $rootScope.$new();

ctrl = $controller('AddMedicalServiceModalCtrl',{
  $scope: scope
  });
}));

it('should create return true if var 1 is greater than var2 , false if other wise',
function(){
  var compare1 = function(){
    var var1 = 1;
    var var2 = 0;
    return var1 > var2;
  }

  var compare2 = function(){
    var var1 = 0;
    var var2 = 1;
    return var1 > var2;
  }

  expect(compare1).toBeTruthy();
  expect(compare2).toBeFalsy();

   });

  });

控制器中的特定功能我试图测试

(function() {
app.controller('AddMedicalServiceModalCtrl',['ProviderMedicalService','Treatment','$scope','$modalInstance',function(ProviderMedicalService,Treatment,$scope,$modalInstance){
    $scope.newTreatment = {}

    $scope.checkless = function(var1,var2){
        var1 = parseInt(var1);
        var2 = parseInt(var2);

        if(var1 > var2){
            return true;
        }
        else{
            return false;
        }
    }
    }]);
   })();

附加信息：我正在使用angular-js和ruby on rails。我知道有jasmine gem可以帮助我。但是我的老板坚持我们应该尝试使用karma来做我们的单元测试/e2 e for anujs部分和rspec for rails。
