javascript - 如何测试这个组件/模板？ :)

Question

我正在寻求有关我的 UNITEST for AngularJS(和 nvd3)问题的任何帮助。

确实，当我尝试制作图表时，我遇到了错误。 就像 $ctrl.data 和 $ctrl.options 完全是空的......

我不明白问题出在哪里，我一整天都在尝试解锁，但没有成功..

如果有人知道问题出在哪里，我提前表示感谢。

代码:

myComp.comp.js:

angular.module('myMod')
        .component('myComp', {
            template: '<div><nvd3 options="$ctrl.options" data="$ctrl.wrapped"></nvd3></div>',
            bindings: {
                data: '<',
                zoom: '<'
            },
            controller: myCtrl
        })

myCtrl.$inject = ['$scope']
function myCtrl($scope) {
    //Here I set wrapped with data
    //and set the options for nvd3
}

myComp.spec.js:

describe('component: myComp', function() {

    beforeEach(module('myComp'));

    var $ctrl,
        $bindings,
        $template,
        scope,
        elmt;

    beforeEach(inject(function($compile, $componentController, $rootScope, $document) {

        $scope = $rootScope.$new();

        $bindings = {
            zoom: true,
            data: [ /*DATA SAMPLE HERE*/ ]
        }

        $ctrl = $componentController('myComp', $scope, $bindings);
        elmt = angular.element('my-comp data="$ctrl.data" zoom="$ctrl.zoom"></my-comp>');
        elmt = $compile(elmt)($scope);

        $scope.$apply();
    }));

    it("test", function () {
        expect(1).toBe(1);
    });
});

karma 报应/ Jasmine :

您错过了开头<在您的模板示例中。

但是，如果您使用 $componentController您不需要编译任何模板，因此可以这样做:

$ctrl = $componentController('myComp', $scope, $bindings);

或者，执行:

$scope.zoom = true;
$scope.data = [ /*DATA SAMPLE HERE*/ ];
elmt = angular.element('<my-comp data="data" zoom="zoom"></my-comp>');
elmt = $compile(elmt)($scope);

$scope.$apply();
$ctrl = elmt.controller('myComp');
