为什么浏览器中的Mocha会从URL而不是从UNC路径抛出检测到的全局泄漏? [英] why mocha in browser throw global leak detected from a url but not from a unc path?
问题描述
我正在创建一个JavaScript库，并希望使用BDD，因此我尝试了摩卡，但我无法使其正常运行.我希望在客户端上使用该库，因此我假设从可浏览的url，在Web连接的上下文中运行它，而不只是从unc路径中的沙箱运行是有意义的.
这是虚拟起点文件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>
当我打开Chrome或Safari浏览器时
file:///Users/me/dev/sandbox/test.html
它按预期方式工作，测试通过，没有错误
当我打开Chrome或Safari浏览器时
http://localhost/sandbox/test.html
我收到以下错误，测试失败
Error: global leak detected: script1339700707078

有人可以解释一下，更好地解决吗?
这是将jQuery与Mocha结合使用的问题. jQuery创建具有唯一ID的全局变量...在您的情况下为script133....最近在mocha 1.2中发布的您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.

I'm creating a javascript library and want to use BDD, so I'm giving a try at mocha and I can't make it work. I want that library to be used on the client, so I'm assuming that it make sense to have it running from a browsable url, to be in a context of web connection, and not just a sandbox from a unc path.
here is the dummy starting point file 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!');
});
});
});
and here is the html page that trigger the test, 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>
when I open in chrome or safari
file:///Users/me/dev/sandbox/test.html
it works as expected, test pass with no error
when I open in chrome or safari
http://localhost/sandbox/test.html
I get the following error and the test fail
Error: global leak detected: script1339700707078

can someone have an explanation, and better a solution?
This was an issue with using jQuery with mocha. jQuery creates global variables that have a unique id... in your case script133.... Recently released in mocha 1.2 you can set up wildcard ignores...
$(function(){
mocha
.globals([ 'script*' ]) // acceptable globals
.run();
});
Make sure you are up to date, and configure appropriately.
