Karma/Jasmine/PhantomJs:未定义不是构造函数 [英] Karma/Jasmine/PhantomJs: undefined is not a constructor

问题描述

我有一个应用程序，在运行测试时会引发一个奇怪的错误.错误如下:

I have an application that raise an odd error when I run tests. The error is the following :

TypeError: undefined is not a constructor (evaluating 'allKeys[i].match(/^[0-9]+$/)') in node_modules/jasmine-core/lib/jasmine-core/jasmine.js (line 2988)
test/spec/core/http/response-spec.js:92:63
loaded@http://localhost:8080/context.js:151:17

这些测试大多数都通过了，但很少有突破.这是一个破坏的测试:

Most of those tests passes, but a very few break. Here is one of the test that breaks:

(function () {
  'use strict';

  describe('MyAccount.core.http.response', function () {
    var ResponseInterceptor = {},
        $httpProvider = {},
        $window = {},
        env = {},
        MessageQueue = {};

    beforeEach(module('MyAccount.core.environment'));
    beforeEach(module('MyAccount.core.http', function (_$httpProvider_, $provide) {
      $httpProvider = _$httpProvider_;

      MessageQueue  = {
        dispatch: jasmine.createSpy('dispatch')
      };

      $window = {
        location: {
          href: jasmine.createSpy()
        }
      };

      $provide.value('$window', $window);
      $provide.value('MessageQueue', MessageQueue);
    }));
    beforeEach(inject(function (_$window_, _ResponseInterceptor_, _env_) {
      $window = _$window_;
      ResponseInterceptor = _ResponseInterceptor_;
      env = _env_;
    }));

    describe('response status', function () {
      // Asserting that 404 and 403 errors are intercepted.
      angular.forEach([404, 403], function (error) {
        describe('is ' + error, function () {
          beforeEach(function () {
            ResponseInterceptor.responseError({
              status: error,
              data: {
                message: 'error ' + error
              }
            });
          });

          it('calls MessageQueue.dispatch with the error message', function () {
            expect(MessageQueue.dispatch).toHaveBeenCalledWith('error ' + error, {
              on: 'global.errors'
            });
          });
        });
      });
    });
  });
})();

我已经坚持了几个小时，似乎找不到解决办法.这是我正在使用的依赖项及其版本:

I've been stuck on that for few hours now and can't seems to find a solution. Here are the dependencies I'm using and their versions:

• 业力:^1.2.0
• 茉莉花芯:^2.5.0
• 业力茉莉花:^1.0.2
• karma-phantomjs-launcher:^1.0.2
• phantomjs:^2.1.7

• karma: ^1.2.0
• jasmine-core: ^2.5.0
• karma-jasmine: ^1.0.2
• karma-phantomjs-launcher: ^1.0.2
• phantomjs: ^2.1.7

注意:这是一个使用角度生成器的全新yeoman应用程序.

NOTE: This is a brand new yeoman application using the angular generator.

推荐答案

我遇到了同样的问题，但片刻之前就解决了.

I had the same problem, but got it solved moments ago.

要重复我在评论中所说的话:当您有两个等于的数组时，无论发生与否，都会发生该错误.如果它们不相等，则会显示标准差，并显示出差异.

To repeat what I said in the comments: The error happens when you have two arrays that are equal, believe it or not. If they are unequal, you get the standard error with the differences shown.

茉莉核2.5.0.于这一天之前于两天前出版.我降级到2.4.1.，它可以工作.

jasmine-core 2.5.0. was published two days ago, as of this moment. I downgraded to 2.4.1., and it works.

似乎是2.5.0.是罪魁祸首.

It seems that 2.5.0. is the culprit.

降级到2.4.1.，直到发布者解决它.

Downgrade to 2.4.1., until the publisher gets it solved.

我的设置:maven/frontend-maven-plugin/karma(*)/phantomJS

My setup: maven/frontend-maven-plugin/karma(*)/phantomJS

(*)也可能在这里说茉莉花".

(*) could probably have said 'Jasmine' here as well.
