错误beforeEach噶'不确定'的范围变量不确定、变量、范围、错误

2023-09-13 04:36:43 作者:点击查看大图

下面是我的2个文件和错误。我正在噶,这里是我的karma.conf.js:https://gist.github.com/devanp92/a87c0bcc2bf5b8e17f64.运行开始因缘之后,我得到这个错误。这是一个非常简单的测试文件(或因此我认为),我仍然得到这些错误。

Main.js - 这是一个控制器

  angular.module('SSLApp')。控制器('MainCtrl',  功能($范围,$ rootScope){    $ scope.thing = 1;}); 

MainSpec.js - 这是我的测试文件

 描述('MainCtrl',函数(){VAR控制器,范围;beforeEach(angular.module('SSLApp'));beforeEach(注(函数($控制器,$ rootScope){    范围= $ rootScope $新的()。    控制器= $控制器('MainCtrl',{        $适用范围:适用范围    });}));它('应该有域中定义'功能(适用范围){    期待(范围).toBeDefined();});}); 
antd Each child in a list should have a unique key prop.

错误!它看起来就像是被称为在var未定义MainCtrl = $控制器...

解决方案

您在您的测试code两个错误。

首先你用错误的模块的功能。该 angular.module()函数提供了一个真正的框架模块,而简单的模块()是 angular.mock.module()的别名,你应该在测试中使用。所以,你应该写你的 beforeEach 的功能如下:

  beforeEach(模块('SSLApp')); 

此外,你定义一个参数测试的情况下的功能,但它应是无参数。在范围变量是从外部范围访问。

 它('应该有域中定义',函数(){    期待(范围).toBeDefined();}); 

Here are my 2 files and error. I am running Karma, here is my karma.conf.js: https://gist.github.com/devanp92/a87c0bcc2bf5b8e17f64. After running 'karma start' I get this error. It is a very simple test file (or so I assume) and I am still getting these errors.

Main.js - This is a controller

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

MainSpec.js - This is my test file

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! It looks like it is being called undefined in the var MainCtrl = $controller...

解决方案

You have two mistakes in your test code.

First of all you use wrong module function. The angular.module() function provides a real framework module while simple module() is an alias for angular.mock.module() which you should use in tests. So you ought to write your beforeEach function as follows:

beforeEach(module('SSLApp'));

Besides, you defined the test case function with a parameter but it should be parameterless. The scope variable is accessible from the outer scope.

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