Answer to this problem was very quite simple. My node server was already running on port 3000. now when I ran npm test, chai-http was starting the node server again see this lineenter image description here

no two server can run on same port, so my node process was exiting upon port conflict and it wasn’t giving me any error that why my test was not working
