Question

我正在与Karma和Jasmine一起编写我的第一个Angular app测试。

我有一个具有此功能的控制器：

function getMyLists() {
  getLists.getOne().then(function(listOne) {
    $scope.list1 = listOne[0];
    list1Available = true;
  });
  getLists.getTwo().then(function(listTwo) {
    $scope.list2 = listTwo;
    list2Available = true;
  });
}

getMyLists();

我已经在测试中模拟了服务

describe('MainCtrl', function () {

  var rootScope, scope, controller, myService;

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

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

    myService = {
      getOne: function(){
        // mock promise
        var deferred = $q.defer();
        deferred.resolve([
          {
            "one": 1
         },
         {
            "type": list
         }
        ]);
        return deferred.promise;
      },
      getTwo: function(){
        // mock promise
        var deferred = $q.defer();
        deferred.resolve([
          {
            "two": 2
         },
         {
            "type": list
         }
        ]);
        return deferred.promise;
      }
    }

    controller = $controller('MainCtrl', {
      $scope: scope,
      myService: myService
    });
  }));

  it('should call myService service and populate the array', function(){
    scope.$digest();
    expect(scope.list1.length).toBeGreaterThan(0);
  });

});

这很好用，我有一个通过测试，正如我所料。但是当我尝试测试以下示例时，我一直都会遇到错误。

expect(scope.list2.length).toBeGreaterThan(0);
Expected undefined to be greater than 0.

expect(list1Available).toEqual(false);
ReferenceError: Can't find variable: list1Available

就像我说这些是我的第一次测试所以感谢任何帮助！

尝试$ rootScope。$ digest（）; //解决/拒绝承诺

 it('should call myService service and populate the array', function(){
    $rootScope.$apply();
    expect(scope.list1.length).toBeGreaterThan(0);
  });

你需要附上list1Available＆amp;＆amp; scope.list2可以使用$ scope，因此可以在控制器外部访问它们。

function getMyLists() {
  getLists.getOne().then(function(listOne) {
    $scope.list1 = listOne[0];
    $scope.list1Available = true;
  });
  getLists.getTwo().then(function(listTwo) {
    $scope.list2 = listTwo;
    $scope.list2Available = true;
  });
}

您的测试需要测试scope.list1Available

expect(scope.list1Available).toEqual(false);

controller $ scope变量在jasmine测试中未定义
