我已经使用 ng-table 创建了一个应用程序，该应用程序工作正常，但是当我编写一个 jasmine 测试用例时，我得到了。

Error: [$injector:unpr] Unknown provider: TableParamsProvider

谁能告诉我如何模拟 ngTableParams 并测试其功能

我的代码如下

Jasmine 测试用例

describe('Testing Controllers', function() {
    describe('Testing WorkController Controller', function() {
        var WorkController, $scope;

        beforeEach(module('wsd.workstations'));

        beforeEach(inject(function($controller, $rootScope) {
            $scope = $rootScope.$new();
            WorkController = $controller('WorkController', {
                $rootScope: $rootScope,
                $scope: $scope
            });
        }));

        it('should searchDocuments when searchDocuments() is called', function() {
            $scope.searchDocuments();
        });
    });
});

脚本

angular.module('wsd', ['restangular', 'ngTable', 'wsd.models', 'wsd.workstations', 'wsd.workperiods', 'ngRoute'])

.config(function(RestangularProvider, $routeProvider) {
    RestangularProvider.setBaseUrl('/rest/myuser');

    $routeProvider.when('/wd', {
        templateUrl: 'main/workstation/main.tpl.html',
        controller: 'WorkController',
        resolve: {
            myWorkDocuments: function(Documents) {
                return Documents.getWorkDocuments();
            }
        }
    }).when('/wp', {
        templateUrl: 'main/workperiod/main.tpl.html',
        controller: 'PeriodController',
        resolve: {
            myWorkPeriods: function(Periods) {
                return Periods.getWorkPeriods();
            }
        }
    }).otherwise({
        redirectTo: '/wd'
    });
});

workstation/main.js

angular.module('wsd.workstations', [])

.controller('WorkController', function($rootScope, $scope, $filter, ngTableParams)
{ 
   $scope.myValues = [{name: "Moroni", age: 50},
                {name: "Tiancum", age: 43},
                {name: "Jacob", age: 27},
                {name: "Nephi", age: 29},
                {name: "Enos", age: 34},
                {name: "Tiancum", age: 43},
                {name: "Jacob", age: 27},
                {name: "Nephi", age: 29},
                {name: "Enos", age: 34},
                {name: "Tiancum", age: 43},
                {name: "Jacob", age: 27},
                {name: "Nephi", age: 29},
                {name: "Enos", age: 34}, 
                {name: "Tiancum", age: 43},
                {name: "Jacob", age: 27},
                {name: "Nephi", age: 29},
                {name: "Enos", age: 34}];

    $scope.tableParams = new ngTableParams({
        sorting: {
            name: 'asc'     
        }
    }, {
        getData: function($defer, params) {
            $scope.myValues = $filter('orderBy')($scope.myValues, params.orderBy());
            $defer.resolve($scope.myValues);
        }
    });


    $scope.searchDocuments = function() 
    {
        // some other logic
    };
});

最佳答案

首先，确保您的应用依赖于 ngTable。它在“main”中吗？

现在进行测试:

beforeEach(inject(function($controller, $rootScope, $filter, ngTableParams) {
    $scope = $rootScope.$new();
    WorkController = $controller('WorkController', {
        $rootScope: $rootScope,
        $scope: $scope,
        $filter: $filter,
        ngTableParams: ngTableParams
    });
}));

请注意您必须如何显式提供每个依赖项作为注入(inject)器的参数。

编辑:如果您不想测试与 $scope.tableParams 相关的任何内容，igorzg 解决方案也可以使用

另一个编辑:你需要让 Angular 知道将什么注入(inject)你的 Controller :

.controller('WorkController', ['$rootScope', '$scope', '$filter', 'ngTableParams', function($rootScope, $scope, $filter, ngTableParams)
{ 
 // your controller code here
}]);

另一个问题是，在您的测试中，您正在加载 wsd.workstations 模块，该模块没有注入(inject) ngTable。所以你需要:

angular.module('wsd.workstations', ['ngTable'])

或在你的测试中:

beforeEach(module('wsd'));

代替:

beforeEach(module('wsd.workstations'));
