我需要测试控制器代码，但我看不到正确的结果，代码如下： “slide”数组长度= 4;但在测试中，我写了“toBe（2）”，我看到了：

PhantomJS 1.9.8（Linux 0.0.0）：执行0 of 0 ERROR（0.035秒/ 0秒）

为什么我看到0个错误，如果我期望2，但是数组长度是4 ???

app.controller('mainCtrl',['$scope', function($scope){
  $scope.slide = [1, 2, 3, 4];
}]);

describe('Tests Controllers', function() {
  beforeEach(module('app'));

  var $controller;

  beforeEach(inject(function(_$controller_, $rootScope){
    $controller = _$controller_;

    it('check slides length, it should be 4', function() {
      var $scope = {};
      var controller = $controller('mainCtrl', { $scope: $scope });
      expect($scope.slide.length).toBe(2);
    });
  }));
});

当Karma无法找到您的测试并显示Executed 0 of 0 ERROR时，导致此行为的最常见原因是：

karma.conf.js选项

files:[]

缺少测试文件/文件夹中的规范（it块），因此Karma无需执行任何操作。如果规范在测试文件中被不适当地放置，也可能发生，例如您将it置于beforeEach内，但Jasmine不支持它。我们的想法是将它们放在同一水平上。 it规范可以在全局范围内单独生存，也可以直接在describe套件块中生效。

使用Jasmine和PhantomJS进行Angular JS测试，0错误
