我正在设置业力来进行一些单元测试,但我无法让它在一个基本的例子上工作:
这是控制器文件:
angular.module('balrogApp.requests', [
/* Dependancies */
])
// Routes configuration
.config(['$routeProvider', function($routeProvider) {
/* $routeProvider configuration */
}])
.controller('requestsController', function(Requests, Users, Projects, RequestsComments, CostEstimations,
Regions, growl, $route, $rootScope, $scope, $location) {
this.test = 'test42';
/* ... */
});
这是测试文件:
describe('requestsController', function() {
beforeEach(module('balrogApp.requests'));
var ctrl;
beforeEach(inject(function($controller) {
ctrl = $controller('requestsController');
}));
it('should have test = "test42"', function(){
expect(ctrl.test).toBe("test42");
});
});
但是抛出了这个错误:

答案 0 :(得分:2)
$scope
(您的控制器所依赖的)是所谓的“本地”,即它特定于控制器的实例并且不存在于依赖注入容器中。你必须自己提供,例如为:
beforeEach(inject(function($rootScope, $controller) {
ctrl = $controller('requestsController', { $scope: $rootScope.$new() });
}));
由于您正在创建新范围,因此最好在测试后将其销毁:
var scope;
beforeEach(inject(function($rootScope, $controller) {
scope = $rootScope.$new();
ctrl = $controller('requestsController', { $scope: scope });
}));
afterEach(function() {
scope.$destroy();
});
