我正在使用拦截401响应的
angular-http-auth模块.此模块广播事件：auth-loginrequired如果有一个401响应,可以使用$on()接收.但是我怎么测试呢？
beforeEach(inject(function($injector,$rootScope) {
$httpBackend = $injector.get('$httpBackend');
myApi = $injector.get('myApi');
scope = $rootScope.$new();
spyOn($scope,'$on').andCallThrough();
}));
describe('API Client Test',function() {
it('should return 401',function() {
$httpBackend.when('GET',myApi.config.apiRoot + '/user').respond(401,'');
myApi.get(function(error,success) {
// this never gets triggered as 401 are intercepted
});
scope.$on('event:auth-loginrequired',function() {
// This works!
console.log('fired');
});
// This doesn't work
expect($scope.$on).toHaveBeenCalledWith('event:auth-loginrequired',jasmine.any(Function));
$httpBackend.flush();
});
});
解决方法
根据你的评论,我认为你不需要任何期望($scope.$on).toHaveBeenCalledWith(…);因为它确保某些东西真正倾听事件.
为了断言事件被触发,你必须准备好所有必要的东西,然后执行导致事件广播的动作.我想这个规范可以通过以下方式概述：
it('should fire "event:auth-loginrequired" event in case of 401',function() {
var flag = false;
var listener = jasmine.createSpy('listener');
scope.$on('event:auth-loginrequired',listener);
$httpBackend.when('GET','');
runs(function() {
myApi.get(function(error,success) {
// this never gets triggered as 401 are intercepted
});
setTimeout(function() {
flag = true;
},1000);
});
waitsFor(function() {
return flag;
},'should be completed',1200);
runs(function() {
expect(listener).toHaveBeenCalled();
});
});
