Perhaps the callback here should be wrapped with common.mustCall(..., N)?

I could go either way on it. I left it without common.mustCall() and used the assert.strictEqual(pongsReceived, N); instead so that it would be readily apparent that it's the analogous check to assert(pingsReceived >= N);.

Stress test with this fix: Stress test on current master (should show lots of failures): |
|
So, looking at the stress test results, these changes greatly reduce the flakiness but don't eliminate it... More to be done... |
|
OK, greatly revised. @mscdex, PTAL. |
|
Stress test passed. CI failure is unrelated test. |
|
LGTM |

Binding this suggests it's somehow important but it's not, is it? It's always undefined, if I read the diff right.

LGTM with a nit. |
There is no guarantee UDP messages will be received. Accommodate the occasional dropped message. This is a functionality test, not a performance benchmark. Speed up the test by not sending 1500 messages across three ports. Fixes: nodejs#4526
|
Nit addressed. CI again: https://ci.nodejs.org/job/node-test-pull-request/1579/ |
|
LGTM |

occasional dropped message.
This is a functionality test, not a performance benchmark. Speed up the
test by sending 5 messages per server rather than 500.
