NODE_ENV和Jest [英] NODE_ENV with Jest

问题描述

我正在从摩卡咖啡迁移到Jest.我的测试将导入"config"包，该包将根据NODE_ENV变量选择一个配置文件或其他配置文件.但是，从Jest运行测试时，看起来好像是在配置中找到了NODE_ENV变量

I am migrating from Mocha to Jest. My test import the 'config' package, which selects a configuration file or another depending on the NODE_ENV variable. However, it looks like NODE_ENV variable is found by config while running the test from Jest

下一行不起作用(即NODE_ENV被忽略):

Next line does not work (that is, NODE_ENV is ignored):

 NODE_ENV=test jest test/*.js --notify --config jest.config.json

因此，"config"包会报告:

As a consequence the 'config' package reports:

console.error node_modules/config/lib/config.js:1727
WARNING: NODE_ENV value of 'test' did not match any deployment config file names. 

您知道如何包含NODE_ENV吗?

Do you know how to include NODE_ENV?

推荐答案

Jest自动将环境变量NODE_ENV定义为test(请参见

Jest automatically defines environment variable NODE_ENV as test(see https://jestjs.io/docs/en/getting-started.html), as you can confirm from your error message:

console.error node_modules/config/lib/config.js:1727
WARNING: NODE_ENV value of 'test' did not match any deployment config file names. 

您可以做的就是简单地创建config/test.json并包含内容{}，这是一个空的有效JSON对象.

What you can do is simply create config/test.json and include the contents {}, which is an empty valid JSON object.

请参见 https://github.com/lorenwest/node-config/wiki /严格模式

注意:当您使用 config 时，发生上述错误.包，与此同时，您在config目录中没有test.json文件.

Note: the aforementioned error occurs when you use the config package, and meanwhile you don't have the test.json file in the config directory.
