我有一个名为
app.js
的 NodeJs Express 服务器,我想使用 nyc
进行代码覆盖。
// app.js
const express = require('express')
const app = express()
const port = 3000
app.get('/', (req, res) => {
res.send({
message: 'Hello World!'
})
})
app.listen(port, () => {
console.log(`Example app listening on port ${port}`)
})
//.nycrc.json

}
}
nyc node server/app.js
http://localhost:3000
,我看到我的屏幕上打印了Hello World!
。.nyc_output
文件创建的文件夹 json
,但是 json 的内容只是一个空对象。nyc report
,我得到一个空报告。我做错了什么?
解决方案是这样做
node node_module/nyc/bin/nyc npm start
