javascript – 在BeforeEach中错误Karma’undefined’作用域变量

这是我的2个文件和错误.我正在运行Karma,这里是我的karma.conf.js： https://gist.github.com/devanp92/a87c0bcc2bf5b8e17f64.运行’karma start’后,我得到这个错误.这是一个非常简单的测试文件(或者我假设),我仍然收到这些错误.

Main.js – 这是一个控制器

angular.module('SSLApp').controller('MainCtrl',function($scope,$rootScope) {
    $scope.thing = 1;
});

MainSpec.js – 这是我的测试文件

describe('MainCtrl',function() {
var controller,scope;

beforeEach(angular.module('SSLApp'));

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

it('should have scope to be defined',function(scope) {
    expect(scope).toBeDefined();
});

});

错误！看起来它被称为未定义的var MainCtrl = $controller …

解决方法

您的测试代码有两个错误.

首先你使用错误的模块功能. angular.module()功能提供了一个真正的框架模块
simple module()是angular.mock.module()的别名,您应该在测试中使用.所以你应该写下你的beforeEach函数如下：

beforeEach(module('SSLApp'));

此外,您使用参数定义了测试用例函数,但它应该是无参数的.范围变量可从外部范围访问.

it('should have scope to be defined',function() {
    expect(scope).toBeDefined();
});
