如何使用createSpy（）使用Jasmine创建模拟对象

Question

I'm trying to set up a mock unit test with jasmine by using createSpy(). I've getting

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

CODE:

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

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

TEST:

 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);
  });

The way you have set up the mock unit test case is correct, the same works for me in this fiddle .

Check the scope in which you've included this part of the code:

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