Question

我创建了一个模拟服务，它就像我的真实服务一样，但为我的单元测试返回一组定义的值。如果我将该模块添加到我的应用程序。它拦截了调用并返回我在模拟中的内容，就像它假设的那样。

但是当我将这个模块添加到我的茉莉花测试中时，我似乎无法获得一个值

beforeEach(module('VideoConference'));//my app
beforeEach(module('lookupServiceMock')); //the mock service
beforeEach(inject(function(Mlb) { // Mlb is a factory that submits requests
    mlb = Mlb;
    spyOn(mlb, 'submitRequest').and.callThrough();
}));
...
it("Should Create a new conference", function () {
    childScope = $scope.$new();
    vm = $controller('TitleAndDateCtrl', { $scope: childScope });             

    childScope.requiredFieldsMet = function () { return true }
    vm.conference.Title = "Test";              
    vm.createConference();
    expect(mlb.submitRequest).toHaveBeenCalled();//this expectation comes back true
});
it("Should have returned a value", function() {
    var id = mlb.get("id");//at this point expect that the id has been set
    expect(id).toBe(123);
});

当我单步执行时，控制器会转到$ http.post（...）的位置，但它不会触发我的模拟或返回值。它不会成功发布。任何想法如何让它击中我的模拟，返回值

您应该将httpMock = $httpBackend;添加到beforeEach。

然后在你的测试中：

it("Should have returned a value", function() {
    httpMock.expectGET('PATH_TO_YOUR_HTTP_GET').respond({id: 123}); 

    var id = mlb.get("id");//at this point expect that the id has been set
    httpMock.flush();        
    expect(id).toBe(123);
});

我不知道你的回应应该如何，所以你应该改变它。
