How about adding a mustCallAtLeast?
(I see that the value of n is asserted, but this will give a one-step-closer-to-root-cause assertion error)

If I understand correctly, the assertion on n will occur before any assertion by mustCallAtLeast().

Should remove (maybe replace with comment // end of test)

the + is cheating the strict
either put on the right side send + '\n' ('\n' is because data comes from console.log)
or replace the 'data' handler with:

  let n = 0;
  child.stdout.setEncoding('ascii');
  child.stdout.on('data', function(d) {
    const c = Number(d);
    if (!c) assert.fail(c);
    n += c;
  });
