AngularJS茉莉花单元测试

Question

我有以下单元测试,由于某种原因,第二次测试使其他测试失败.

beforeEach(inject(function ($rootScope, _$httpBackend_, $controller, $location, mockedResource) {
    scope = $rootScope.$new();
    httpBackend = _$httpBackend_;
    locationService = $location;

    ctrlDependencies = {
        $scope: scope, 
        resource: mockedResource,
    }

    var ctrl = $controller('myController', ctrlDependencies);
}));

it('should redirect to a new page', function() {
    scope.pageRedirectFunction();
    expect(locationService.path()).toBe('/newpage')
});

it('should delete an epic resource', function() {
    httpBackend.expectGET('/api/v1/epic/1').respond({});
    httpBackend.expectDELETE('/api/v1/epic/1').respond({});

    // Run the deletion function
    scope.deleteEpicResource()

    httpBackend.flush() // This line seems to be the rebelious one

    expect(scope.epicResources.length).toEqual(0)
})

我已经设法弄清楚似乎导致错误的httpBackend.flush()线,这就是线.为什么flush函数会导致奇怪的行为？

我karma start在终端中运行命令得到的实际错误是:

 Delaying execution, these browsers are not ready: Chrome 29.0 ....

过了一会儿,Chrome会话就崩溃了.

关于使用 jasmine 和 AngularJS 测试/模拟异步请求的鲜为人知的技巧：

如果您没有在测试中显式调用该请求（即通过另一个函数调用它），该请求将不会被 Angular 消化，因此看起来好像该请求从未触发（当您调用flush()）

尝试在通话scope.$digest()之前运行httpBackend.flush()，这可能会起作用。请参阅本主题以获取更多信息。
