错误beforeEach噶'不确定'的范围变量 [英] Error Karma 'undefined' scope variable in beforeEach

问题描述

下面是我的2个文件和错误。我正在噶，这里是我的karma.conf.js：<一href=\"https://gist.github.com/devanp92/a87c0bcc2bf5b8e17f64\">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（）;
}）;}）;
 

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();
});
