我有以下茉莉花测试：
- it('should resolve promise',inject(function ($q,$rootScope) {
- function getPromise(){
- var deferred = $q.defer();
- setTimeout(function(){
- deferred.resolve(true);
- },1000);
- return deferred.promise;
- }
- var p = getPromise();
- var cb = jasmine.createSpy();
- runs(function(){
- expect(cb).not.toHaveBeenCalled();
- p.then(cb);
- $rootScope.$apply();
- });
- waitsFor(function(){
- return cb.callCount == 1;
- });
- runs(function(){
- expect(cb).toHaveBeenCalled();
- $rootScope.$apply();
- });
- }));
我认为$rootScope.$apply应该解决所有未完成的承诺,但不知怎的,它不会在这个测试中发生.
如何在这样的测试中触发promise解析？请帮忙！
我认为$rootScope.$apply()在你的情况下很快被调用.这应该工作：
- function getPromise(){
- var deferred = $q.defer();
- setTimeout(function(){
- deferred.resolve(true);
- $rootScope.$apply();
- },1000);
- return deferred.promise;
- }
更新
你可以注入mock $timeout service并使用$timeout.flush()显式解决这个问题.
- it('should resolve promise',$timeout,$rootScope) {
- function getPromise(){
- var deferred = $q.defer();
- $timeout(function(){
- deferred.resolve(true);
- },1000);
- return deferred.promise;
- }
- // ...
- $timeout.flush();
- // ...
