在我directive
召唤的data-type-ahead
内,我在以下一系列事件中有以下内容:
$scope.test = 5;
// Bind blur event and clear the value of
element.bind('blur', function(){
$scope.test = 0;
});
我已尝试在单元测试中使用大量内容来正确测试此blur
事件的功能但是我没有成功。我已经看到了函数triggerHandler
的提及。以下是我对单元测试的尝试:
//Inject $compile and $rootScope before each test.
beforeEach(inject(function(_$compile_, _$rootScope_) {
$compile = _$compile_;
$rootScope = _$rootScope_;
$scope = $rootScope.$new();
$scope.test = 5
html = angular.element('<input type="text" data-type-ahead/>');
//Apply $scope to directive html.
directive = $compile(html)($scope);
//Trigger digest cycle.
$scope.$digest();
}));
it('should trigger the events bound to the blur event on the directive', function() {
html.triggerHandler('blur')
expect($scope.test).toEqual(0);
});
然而这是失败的,因为$scope.test
仍然存在于5.是否html元素不正确,在触发事件后是否需要另一个$digest
或$apply
?
