如何彻底退出CI的npm服务器测试？

Question

I've been developing a node based server that I want to have tested on Travis-ci, the problem is the only thing I want to test now is if the server has any errors on start

(It's just a backend for serving an API; all it does on start is serve out of a port).

If it starts fine, I don't want it to run forever on the CI's VM. I've tried having the test script in my package.json point to a bash script that uses kill with the PID but that doesn't exit cleanly to pass Travis's build.

Long story short, what should I write to have my test run npm start for a couple of seconds and then close node cleanly if there are no errors?

Answer 1

You could add a wrapper around your server that you run as your test in which you can exit after x amount of seconds or if an error occurs. Something like this:

require('./myserver') // i asume this starts your server
setTimeout(() => process.exit(0), 5000) // exits with 0 exit code after 5 seconds
process.on('uncaughtException', (err) => {
  console.log(err)
  process.exit(1)
})
