How to crash a Node.js app programmatically (for test)

Question

I want to test a Node.js app crash, need the process stop, not just throw some errors.

Is there a simple way to do it programmatically?

app.get('/crash', function() {
  //do something to crash it 
})

Answer 1

Try this:

app.get('/crash', function() {
  process.nextTick(function () {
    throw new Error;
  });
})

process.nextTick is required to make error asynchronous, otherwise Express will catch it.

Answer 2

process.exit(1)

http://nodejs.org/api/process.html#process_process_exit_code

process.kill(process.pid)

http://nodejs.org/api/process.html#process_process_kill_pid_signal

Both will exit the process.
