That is a bad way of fixing a flaky test IMO. I'll try to reproduce that locally and fix it accordingly. For now we can merge that in to unflake it |

Hope to have a better reasoning on #21544 and re-enabling two skipped tests. With that PR there are two things happening 1. the timeout increases as I couldn't think of anything else other than the worker is not fast enough to spin up. 2. When something crashes for some reason it fails fast rather than waiting for the timeout to be over, including a better error description with the code and the signal. Maybe then the reasoning is better of what is actually happening (in case it fails before)

Summary
Skips the flaky Cloudflare integration test
suites/tracing/durableobject/test.ts > allows RPC methods to access private class fields, which intermittently fails in CI.Root cause
This is a wrangler-based Cloudflare integration test. Each test case spins up its own
wrangler devprocess, mock Sentry server, and Durable Object before exchanging requests, then waits for the expected transaction envelopes within the suite's 20stestTimeout(dev-packages/cloudflare-integration-tests/vite.config.mts). Under CI load, the combined cost of wrangler cold start + DO RPC round-trips + transaction flush occasionally exceeds that budget, so the test times out — matching the "Other / Unknown" flakiness reported here.The test logic itself is deterministic:
/custom-greetingcallssetGreeting('Howdy')thensayHello('partner')on the same DO (idFromName('test')), and the harness matches the two RPC transactions inunordered()mode. There is no logic-level race in the SDK code path being exercised — the flake is environmental/timing.This mirrors the existing precedent in the same package for flaky, timing-out DO RPC integration tests:
suites/tracing/durableobject-spans/test.tsis alreadyit.skip-ped with a// TODO: unskip - this test is flaky, timing out in CIcomment. This change applies the same additive guard (and the same TODO comment, referencing this issue) so the regression coverage can be restored once the timing flake is addressed.Fixes #21201
