控制器方法使用AngularJs中的Karma调用Jasmine单元测试套件

Question

I am pretty new to Karma and Jasmine which I am using to write unit tests for my AngularJs application.

While running the test suite functions which I have called to initialize data in my controller is getting called by default. Is there any way to avoid this call while running the test suite?

Find the code snippet below:

BaseCtrl.js

App.controller('BaseCtrl', ['$scope', '$rootScope', 'Data', function($scope, $rootScope, Data){
    //initialize
    $rootScope.loader = false;
    $rootScope.data = false;

    $scope.init = function(){
        $rootScope.loader = true;
        Data.init(function(data){
            $rootScope.loader = false;
            $rootScope.data = data;
        });   
    };

    $scope.init();
}])

Data.js

App.service('Data', ['$http', function($http){
    return {
        init:function(callback){
            $http.get('/url').success(function(response){
               callback(response);
            });
        }
    };
}]);

BaseCtrl.spec.js

describe('BaseCtrl', function(){
    beforeEach(module('app'));

    var $controller, $rootScope, $scope;

    beforeEach(inject(function(_$controller_, _$rootScope_){
        $controller = _$controller_;
        $rootScope = _$rootScope_.$new();
    }));

    describe('Loader', function(){
        var controller, $scope = {};
        beforeEach(function(){
            controller = $controller('BaseCtrl', {$scope:$scope, $rootScope:$rootScope});
        });

        it('should be false by default', function(){

            // Check the default value
            expect($rootScope.loader).toBe(false);

            // Some code to determine the call, then

            expect($rootScope.loader).toBe(true);

            // Some code to determine the call is done, then

            expect($rootScope.loader).toBe(false);
        });
    });
});

是的，使用$httpBackend创建一个模拟并返回您想要的任何内容。

$httpBackend.when('GET', '/url').respond({});
