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

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

为什么我看到 0 错误，如果我期望 2，但数组长度是 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 找不到您的测试和显示Executed 0 of 0 ERROR时，导致此行为的最常见原因是：

  • 选项中测试文件/文件夹karma.conf.js的错误路径files:[]
  • 测试文件/文件夹中缺少规范（it块），因此 Karma 没有什么可执行的。如果在测试文件中不恰当地放置规范，也可能会发生这种情况，例如在您的情况下，您已经放入it其中beforeEach，但 Jasmine 不支持它。我们的想法是将它们放在同一水平上。itspec 可以单独存在于全局范围内，也可以直接存在于describe套件块中。
