Integration test improvements #2858

hubertdeng123 · 2024-03-05T18:48:05Z

This PR adds a couple of improvements to our integration test pipeline.

Parallelizes some tests, runtime was 23+ minutes. Now this is decreased to <18 minutes
Reports failures to Sentry project

In order to report flakes, I wanted to cut down the time it takes to actually run these tests. Given that with 20 min tests, it could take an hour if the tests flake twice.

I don't understand how this is going to help. Can you share your thinking?

Please ignore things going on in this branch for now, I am just using this as a means to run CI while I am experimenting

docker run is slower than just an exec into a running container

It is but it is also intentional to keep the run separate from the main web process.

That said for a one-off thing like this, I think using exec is a good compromise if it saves a notable amount of time. I'd just want it documented with a brief comment.

integration test (v2.0.1, /usr/local/lib/docker/cli-plugins) and integration test (v2.7.0, /usr/local/lib/docker/cli-plugins) are expected and pending because of branch protection rules, if this PR goes in I'll change those

+        with:
+          max_attempts: 3
+          timeout_minutes: 10


Any chance this could actually increase the flake rate, due to timeouts becoming more frequent? Or are flakes caused by the actions itself timing out?

The typical install logic takes around 4-5 minutes. I doubled that time for the timeout so I don't think this should ever increase the flake rate.

+        with:
+          max_attempts: 3


Just so I understand: what was the behavior before you added these settings? Unlimited retries? No timeout so it hung until the action crashed?

The tests would fail from flakes way too often, adding this in drastically increases the chance the tests pass when they should

So, in effect, the previous (implicit) setting was max_attempts: 1? Or timeout_minutes: Infinity? Or some combination of the two? I get that the problem we are trying to solve is flakiness, I'm just not clear how changing (raising? lowering?) max_attempts and timeout_minutes helps that, since it's not obvious what the current state of affairs is.

Yep, that's correct. The max_attempts really is just the first step into adding flaky test detection. If a job fails, but then is retried and succeed, it can be marked as flaky. The timeout_minutes is a required parameter here. I can remove this and readd in a follow-up PR if that is more clear

No, that's fine. I just wanted to understand the change. LGTM!

Odd to me that we set REPORT_ISSUES=0 above, but then send an envelope here anyway? Maybe I am misunderstanding something, but why would we not just do REPORT_ISSUES=1, and maybe figure out some way to configure it to send to an "integration tests" or similar project on our actual dogfood instance?

Sure, I can incorporate this into the existing logic for REPORT_ISSUES I believe.

+echo y | $dc exec web sentry createuser --force-update --superuser --email $TEST_USER --password $TEST_PASS


What happens if we exec into the web container but it isn't ready yet? Does docker wait until it is ready, or does this fail? If it's the former, we should echo "Waiting for Sentry..." before this runs, otherwise the user may be waiting a while. If it fails, we should add some sort of sync point to wait for the container to be up before trying this.

Docker compose up will only succeed if the container healthcheck for web passes, so I don't think this will be a problem. That is performed on a previous line, so when the tests get to the createuser logic the web container will always be ready

Love the changes. BTW not sure how much time it costs us but maybe we can also use system-installed versions of jq and curl if we detect them and use the Docker-based ones as a fallback?

Good point, I can investigate that in a follow up
