How can I run mocha with npm script?
提问by Kris
I have implemented a testcase for my script and it runs pretty fine when I execute it in Webstorm with the configuration for mocha.
我已经为我的脚本实现了一个测试用例，当我在 Webstorm 中使用 mocha 配置执行它时，它运行得非常好。
The name of my test script is adminTest.js.
我的测试脚本的名称是 adminTest.js。
Now I like to have a npm script to run it from the console or later from the build server.
现在我喜欢使用 npm 脚本从控制台或稍后从构建服务器运行它。
Therefor I have made a script entry in my package.json
因此，我在 package.json 中创建了一个脚本条目
Here is the complete file:

When I start the script with npm run testfrom the console it leads to this error:
当我npm run test从控制台启动脚本时，它会导致此错误：

Your script definition should not include node:
您的脚本定义不应包括node：
"scripts": {
"test": "./node_modules/mocha/bin/mocha tests/**/*Test.js --reporter spec"
},
Or, if mocha is installed globally:
或者，如果 mocha 是全局安装的：
"scripts": {
"test": "mocha tests/**/*Test.js --reporter spec"
},
See also: Configure node npm package.json so that "npm test" works on both unix and windows.
另请参阅：配置节点 npm package.json 以便“npm test”适用于 unix 和 windows。
Update: Ah is see you are working on windows, try changing the script as mentioned in the above post:
更新：啊，看到你在 Windows 上工作，尝试更改上面帖子中提到的脚本：
"testOnWindowsUseThis" : "node node_modules/mocha/bin/mocha"
