[英]Angularjs Unit Test - function to be defined
How do i check whether a particular function is defined or not? 如何检查特定功能是否已定义?
I am using following unit test, doesn't work. 我使用以下单元测试,不起作用。
controller 调节器
$scope.filterData = function () {
$scope.currentPage = "1";
$scope.displayData($scope.currentPage);
......
}
test 测试
var ctrl, scope;
beforeEach(function () {
// load the module
module('myApp');
// inject Controller for testing
inject(function ($rootScope, $controller) {
scope = $rootScope.$new();
ctrl = $controller('DataCtrl', { $scope: scope });
});
});
it('should have a filterData function to be defined', function () {
expect(scope.filterData()).toBeDefined();
});
Remove the braces like this: 删除这样的大括号:
it('should have a filterData function to be defined', function () {
expect(scope.filterData).toBeDefined();
});
Since you dont wanna execute the function itself, but only check if its there. 既然你不想执行函数本身,但只检查它是否存在。
