I think this loop is still needed?

next();

Does this test even do anything without this loop?

Is the below code work? It doesn't complain when I run test.

'use strict';
const common = require('../common');
const assert = require('assert');

const N = 3;
let count = 0;
function next() {
  const immediate = setImmediate(common.mustCall(() => {
    clearImmediate(immediate);
    ++count;
  }));
}

for(let i = 0; i < N; i++) {
  next();
}

If it doesn't complain, that means the test is passing (or possibly not even doing anything). I think you should:

  1. Put the for loop back.
  2. Remove the count variable.
  3. Drop the second argument to common.mustCall() as @mscdex said.


process.on('exit', () => {
assert.strictEqual(count, N, `Expected ${N} immediate callback executions`);
});
for(let i = 0; i < N; i++) {
next();
}
