我正在尝试为在angularJS上构建的现有SPA项目编写单元测试用例。每当我尝试执行代码时,我都会收到“找不到变量:模块”错误。
我使用npm安装了库。
我使用了 Chutzpah 和 Jasmine 库。
(function () {
'use strict';
angular.module('app', [
'ngMessages',
'ui.router',
'ui.router.title'
]).run(['REQ_TOKEN', function (REQ_TOKEN) {
//...
}]).config(['$httpProvider', function ($httpProvider) {
$httpProvider.defaults.headers.common["X-Requested-With"] = 'XMLHttpRequest';
}]);
})();
(function () {
'use strict';
window.deferredBootstrapper.bootstrap({
element: window.document,
module: 'app',
resolve: {
REQ_TOKEN: ['$http', function ($http) {
return $http.get('/.../', { ignoreLoadingBar: true, params: { ts: new Date().getTime() } });
}]
}
});
})();
(function () {
'use strict';
angular
.module('app')
.controller('appController', appController);
appController.$inject = ['apiServices', '$scope'];
function appController(apiServices, $scope) {
$scope.value = 5;
}
})();
(function () {
'use strict';
angular
.module('app')
.factory('apiServices', apiServices);
apiServices.$inject = ['$http', '$log', '$q'];
function apiServices($http, $log, $q) {
var clientServicesPath = '/api/ClientServices',
service =
{ ....... };
return service;
}
})();

我收到以下错误:

0通过,1次失败,1次(chutzpah)。
我已经尝试了所有可能的解决方案,但没有一个对我有效。我通过右键单击Test控制器文件并选择“Run JS Tests”选项直接运行测试。
我觉得有更多的配置。请帮帮我。

这不是您将控制器服务传递给测试的方式,而是使用forEach创建新的var ctrl
变量。此外,每个应用程序都有一个注射器实例。您必须使用相同的inject(...)
<强>错误强>
var ctrl = $controller('appController', { $scope: scope, apiServices: apiServices });
从右强>
describe('When using appController ', function () {
var ctrl, scope, apiServices;
beforeEach(inject(function ($controller, $rootScope) {
// Put it here for the sake of organization
//initialize Angular
module('app');
scope = $rootScope.$new();
// Get controller instance
ctrl = $controller('appController');
// Get service instance
apiServices = $injector.get('apiServices');
}));
it('initial value is 5', function () {
expect(scope.value).toBe(5);
});
});

根据deferredBootstrapper的文件,
因为deferredBootstrapper的常量会添加到你的 应用程序模块在单元测试中不可用 有意义的是在全球的beforeEach()中提供它们:
因此, appControllerSpec.js 应为
