ACK, trying to reproduce and debug.

[gireeshpunathil]

Ran a 1000 times locally, not reproducible.

From the error description, looks like this line thew the error:

  assert.strictEqual(expected.useColors, repl.useColors,
                     `Expected ${inspect(expected)} with ${inspect(env)}`);

and from the test logic, it would hint to the first test, that correponds to:

    env: {},
    expected: { terminal: true, useColors: true }

(by matching the expected values, and the then state of environment).

If there is some difference between my local and the CI, this reduced test should show that up.

const stream = require('stream');
const REPL = require('internal/repl');
const assert = require('assert');

const env = {};
const expected = { terminal: true, useColors: true };
const opts = {
  terminal: true,
  input: new stream.Readable({ read() {} }),
  output: new stream.Writable({ write() {} })
};

REPL.createInternalRepl(env, opts, function(err, repl) {
  assert.strictEqual(expected.useColors, repl.useColors);
});

Can someone with access to the CI (AIX) run this a 1000 times please?

@gireeshpunathil It reproduces reliably on one of the two hosts in CI. I took that host offline. @refack is looking at it now. If you want, hop into IRC #node-build and chat with him.

I'm going to close this one in favor of nodejs/build#984 because I strongly suspect this is a build issue and not a test issue.
