From f5b3dc976c315976788bfb8b75bd0b8a40509324 Mon Sep 17 00:00:00 2001 From: Ed Santiago Date: Mon, 19 Oct 2020 12:30:31 -0600 Subject: Tests: Fix common flakes, and improve apiv2 test log - apiv2 - the 'ten /info requests' test is flaking often, taking ~8 seconds (our limit is 7, up from 5 a few weeks ago). Brent suggested that the first /info call might be expensive, because it needs to access storage. So, let's prime it by running one /info outside the timing loop. And, because even that continues to fail, bump it up to 10 seconds and file #8076 to track the slowdown. - toolbox test - WaitForReady() has timed out, even on one occasion causing a run failure because it failed 3 times. Solution: bump up timeout from 2s to 5s. Not really great, but CI systems are underpowered, and it's not unreasonable that 2s might be too low. - sdnotify test - add a 'podman wait' between stop & rm. This may prevent a "cannot rm container as it is running" race condition. While working on this, Brent and I noticed a few ways that test-apiv2 logging can be improved: - test name: when request is POST, display the jsonified parameters, not the original input ones. This should make it much easier to reproduce failures. - use curl's "--write-out" option to capture http code, content type, and request time. We were getting the first two via grep from logged headers; this is cleaner. And there was no other way to get timing. We now include the timing as X-Response-Time in the log file. - abort on *any* curl error, not just 7 (cannot connect). Any error at all from curl is bad news.
