带有额外选项或参数的Mocha测试 [英] Mocha tests with extra options or parameters

问题描述

我正在使用Mocha为Node.js应用程序编写测试用例.测试用例需要一个API密钥作为额外的输入选项或参数. API密钥是私有的，因此我不想将其直接包含在测试文件中，因为每个人都可以在GitHub上看到它.我知道可以在以下位置找到适用于Mocha的一些选项:

I am writing test cases for my Node.js application using Mocha. The test cases need an API key as an extra input option or parameter. The API key is private, so I don't want to include it directly in the test files as everyone then can see it on GitHub. I know there are some options available for Mocha at:

http://mochajs.org/#usage

但是是否可以包含一些参数，以使测试人员可以在命令行中为测试指定自己的API密钥?如:

But is it possible to include some parameters to let testers specify their own API key for the test in the commandline? Such as:

./node_modules/mocha/bin/mocha test/*.js --key YOUR_KEY

推荐答案

我不认为Mocha本身支持向测试传递额外的参数，但是您可以使用环境变量:

I don't think Mocha itself supports passing extra parameters to your tests, but you could use environment variables:

env KEY=YOUR_KEY mocha test/*.js # assumes some sort of Unix-type OS.

并在测试文件中读取它们:

And read them in your test files:

var key = process.env.KEY;
