Node.js-为什么在用摩卡和僵尸进行测试时会泄漏? [英] Node.js - why do I get leaks when testing with mocha and zombie?

问题描述

我试图使僵尸程序与Mocha一起使用，但是除非我使用mocha --ignore-leaks命令选项，否则我的测试将始终失败，并显示以下错误:

Error: global leaks detected: k, i, name, chars, char

我的测试看起来与该线程中解释的完全相同: Mocha和ZombieJS

我希望我可以在这里发布我的问题，但是作为一个新手，我不能在主题上发表评论，只能提出一个新问题.

您知道我为什么会收到这些泄漏吗?我正在使用摩卡咖啡1.0.3和僵尸1.0.0.

解决方案

泄漏可能来自您自己的代码，也可能来自您使用的node_modules. Mocha应该对泄漏的位置给出一些提示，例如忘记使用 var 声明局部变量.

// global leaks
a = 1;

// no leaks
var a = 1;

您还可能会对用coffeescript编写Node.js应用程序感兴趣，因为它可以帮助您避免发生此类错误. (它会使用var 自动初始化变量). http://coffeescript.org/

I've tried to make zombie work with mocha, but unless I use the mocha --ignore-leaks command options, my test always fails with the error:

Error: global leaks detected: k, i, name, chars, char

My test looks exactly like the one explained in this thread: Mocha and ZombieJS

I wish I could have posted my question there, but as a newbie, I cannot comment on the thread, only ask a new question.

Do you have any idea why I get these leaks? I'm using mocha 1.0.3 and zombie 1.0.0.

解决方案

The leaks can come either from your own code or from node_modules that you use. Mocha should give some hints on where the leaks are, such as forgetting to declare local variable with var.

// global leaks
a = 1;

// no leaks
var a = 1;

You might also be interested writing Node.js app in coffeescript since it helps you avoid mistakes like that. (It automatically initializes variables, using var) http://coffeescript.org/
