Question

在下面的代码中，userService.addPreference被模拟，$ state.go也是如此，但$ state.go的调用计数始终为零。我在设置userService.addPreference模拟方法时可能会遗漏一些东西吗？

正在进行单元测试的代码

      userService.addPreference(preference).then(function (dashboard) {
              $state.go('authenticated.dashboard.grid', {id: dashboard.id});
            });

单元测试模拟方法和单元测试

sinon.stub(userService, 'addPreference', function (preference) {
                var defer = $q.defer();
                defer.resolve(preference);
                return defer.promise;
            });
sinon.stub($state, 'go', function () { });
    it('dashboard.confirm should call $state.go', function () {
        vm.confirm();//this is the function containing code being unit tested
        expect($state.go.callCount).to.equal(1);//this is always ZERO and so failing
    });

userService.addPreference(preference).then(function (dashboard) {
              $state.go('authenticated.dashboard.grid', {id: dashboard.id});
            });

涉及异步回调，除非我们明确告诉它，否则不会触发。要强制回调评估，我们需要使用$scope.$apply运行摘要周期，因此请将测试代码更改为：

  it('dashboard.confirm should call $state.go', function () {
        vm.confirm();//this is the function containing code being unit tested
        $scope.$apply();
        expect($state.go.callCount).to.equal(1);//this is always ZERO and so failing
    });

请记住，顺序流回调永远不会被触发。
