我在我已经开发的Angularjs应用程序中尝试使用Jasmine和karma设置单元测试，如解释here。
我为我的控制器创建了一个简单的测试文件：
describe('controller test', function() {
beforeEach(module('ipaApp'));
var $controller, $rootScope;
beforeEach(inject(function(_$controller_, _$rootScope_) {
// The injector unwraps the underscores (_) from around the parameter
// names when matching
$controller = _$controller_;
$rootScope = _$rootScope_;
}));
describe('$scope.grade', function() {
it('sets the strength to "strong" if the password length is >8 chars',
function() {
var $scope = $rootScope.$new();
var controller = $controller('reportViewCardController', {
$scope : $scope
});
$scope.password = 'longerthaneightchars';
$scope.grade();
expect($scope.strength).toEqual('strong');
});
});
});
以下是我的karma.conf.js

module.exports = function(config) {
config.set({

}
但是在使用karma start运行业力时，我遇到了以下错误：

即使在包含ngMock依赖关系后仍未解决。这里出了什么问题？
