Question

这是我的2个文件和错误。我正在运行Karma，这是我的karma.conf.js：https://gist.github.com/devanp92/a87c0bcc2bf5b8e17f64。跑完“业力开始”后＃39;我收到这个错误。这是一个非常简单的测试文件（或者我假设），我仍然会收到这些错误。

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();
});

});

ERROR！看起来它在var MainCtrl = $ controller ...

中被称为undefined

您的测试代码中有两个错误。

首先，您使用了错误的模块功能。 angular.module()函数提供了一个真正的框架模块简单 module（）是angular.mock.module()的别名，您应该在测试中使用它。因此，您应该按如下方式编写 beforeEach 函数：

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。可以从外部作用域访问scope变量。

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

在beforeEach中错误Karma'undefined'范围变量
