为什么浏览器中的mocha会从URL中检测到全局泄漏而不是从unc路径中检测到?

我正在创建一个javascript库并且想要使用BDD,所以我试试mocha而我无法使其工作。我希望在客户端上使用该库,因此我假设从可浏览的URL运行它是有意义的,在web连接的上下文中,而不仅仅是来自unc路径的沙箱。

这里是虚拟起始点文件test / test.foobar.js

var assert = chai.assert;

var foobar = {
  sayHello: function() {
    return 'Hello World!';
  }
};

describe('Foobar', function() {
  describe('#sayHello()', function() {
      it('should work with assert', function() {
      assert.equal(foobar.sayHello(), 'Hello World!');
    });

  });
});

这是触发测试的html页面,test.html

<html>
<head>
  <meta charset="utf-8">
  <title>Mocha Tests</title>
  <link rel="stylesheet" href="testing/mocha.css" />
  <script src="testing/jquery.js"></script>
  <script src="testing/mocha.js"></script>
  <script>mocha.setup('bdd')</script>
  <script src="testing/chai.js"></script>
  <script src="test/test.foobar.js"></script>
  <script> $(function() { mocha.run(); }) </script>
</head>
<body>
  <div id="mocha"></div>
</body>
</html>

当我在chrome或safari中打开时

file:///Users/me/dev/sandbox/test.html

它按预期工作,测试通过没有错误

当我在chrome或safari中打开时

http://localhost/sandbox/test.html

我收到以下错误,测试失败

有人可以解释,更好的解决方案吗?

这是使用jQuery与mocha的问题。 jQuery创建具有唯一ID的全局变量...在您的情况script133...中。最近在mocha 1.2中发布,你可以设置通配符忽略......

$(function(){
  mocha
    .globals([ 'script*' ]) // acceptable globals
    .run();
});

确保您是最新的,并进行适当的配置。

我找到了解决Safari中问题的解决方案...... 替换

<script> $(function() { mocha.run(); }) </script>

通过

<script>
      onload = function(){
        var runner = mocha.run();
      };
</script>

...但仍然在chrome中出错: - (
