javascript - 如何使用 createSpy() 使用 Jasmine 创建模拟对象

Question

我正在尝试使用 createSpy() 使用 jasmine 设置模拟单元测试。我得到了

TypeError: undefined is not a function (evaluating jasmine.createSpy().andCallFake(function(msg) { return [] })) (line 13).

代码:

  $scope.workInit = function() {
    $scope.work_loading = true;
    $scope.public_work_loading = true;

    var projects = SomeService.getGroups();
    var publicProjects = SomeService.getPublicGroupings('G');
    …
     ...
  }

测试:

 this.SomeService = {
    getGroups: jasmine.createSpy().andCallFake(function(msg) { return [] }),
    getPublicGroupings: jasmine.createSpy().andCallFake(function(msg) { return [] }),
}

  it('should expect work_loading and public_loading to be false', function () {
    this.scope.workInit();
    expect($scope.work_loading).toEqual(false);
    expect($scope.public_work_loading).toEqual(false);
  });

您设置模拟单元测试用例的方式是正确的，同样适用于 this fiddle 中的我.

检查您包含这部分代码的范围:

this.SomeService = {
    getGroups: jasmine.createSpy().andCallFake(function(msg) { return [] }),
    getPublicGroupings: jasmine.createSpy().andCallFake(function(msg) { return [] }),
