I made some changes to the Node.js source code and wondered about whether these changes are valid. 我对Node.js源代码进行了一些更改，并想知道这些更改是否有效。 But I don't know how to run the tests written before in the "tests" folder. 但是我不知道如何运行之前在“ tests”文件夹中编写的测试。

I've been exploring the source code of Node.js recently in order to do some research. 为了进行一些研究，我最近一直在探索Node.js的源代码。 I use an early version of Node.js but I think it won't make much difference in testing. 我使用的是早期版本的Node.js，但我认为它在测试中不会有太大的不同。 I found there are test files written in javascript and c. 我发现有用javascript和c编写的测试文件。 Additionally there is a python file in each folder together with its js test files. 此外，每个文件夹中都有一个python文件及其js测试文件。 First I searched issues in GitHub repository for help about testing Node.js source code but failed. 首先，我在GitHub存储库中搜索问题，以寻求有关测试Node.js源代码的帮助，但失败了。 Then I asked Google but just got the answer about using Mocha or other tools to test programs running on Node.js. 然后我问Google，但是得到了有关使用Mocha或其他工具测试在Node.js上运行的程序的答案。 I also searched on stackoverflow but sadly found there is no answers for my question. 我也搜索了stackoverflow，但可悲的是我的问题没有答案。 A tests folder of Node.js has structure like this: Node.js的测试文件夹的结构如下：

tests folder structure 测试文件夹结构

I've tried to use python to run the python file in tests folder but failed. 我试图使用python在tests文件夹中运行python文件，但是失败了。 After reading the relevant code, I thought it should work but:< 阅读相关代码后，我认为它应该可以工作，但是：
Also I tried to use nodejs to run the javascript files. 我也尝试使用nodejs运行javascript文件。 Some of tests ran but some of them didn't output. 一些测试已经运行，但其中一些没有输出。 But running tests one by one is inefficient, I think there should be something wrong about my actions. 但是，一个接一个地运行测试效率低下，我认为我的行为应该有问题。
