CircleCi: Nodejs must be start before run npm test - node.js

Question

I am new to Circle ci. I'm integrating it into my project and am running into a rather puzzling problem. Specifically locally I have to npm start nodejs server and run npm run test. Everything is as expected with a passing case. But when deploying to circle ci, I get an error. And my guess is that nodejs didn't actually launch to run this simple test case. I have referenced from this project https://github.com/punkdata/nodejs-circleci and it works locally like my project. But strangely it works fine with circle ci. Can someone help me where is the wrong point. Thank you.
