ci(tests): scale timing watchdogs and per-test timeout for loaded CI runners - #1600
Conversation
…runners
The unsharded macOS control lane (and occasionally a Linux shard) flaked on
timing, not logic — different tests each run, all deadline-shaped:
- Bun's default 5s per-test timeout pre-empting tests whose real retry
windows + server round-trips exceed 5s under runner contention
('this test timed out after 5000ms' in PR #1596 runs and the main
promotion run; Linux shard hit the same class at 5003ms)
- hardcoded 1-2s in-test websocket/cleanup watchdogs rejecting before the
server answers under load (server-auth WS terminal 1s x3,
provider-option fixture WS 2s, relay cleanup 2s, ...)
Fixes:
- tests/helpers/ci-watchdog.ts: watchdogMs() gives short in-test watchdogs a
10s floor when CI=true; local behavior unchanged (watchdogs bound hung
tests, they do not assert latency)
- ci.yml macOS lane + scripts/ci/run-bun-test-batches.sh: bun test gets
--timeout 20000 so CI load cannot pre-empt a test's own internal deadline
handling (assertions unchanged; the 30m job timeout stays the backstop)

Adding --timeout 20000 between --isolate and tests breaks the existing workflow contract test: tests/ci-workflows.test.ts:176 still requires the macOS step to contain bun test --isolate tests, and line 186 uses the same substring to locate the step. Consequently the Linux shard containing that test fails unconditionally, and the subsequent crash-retry assertions inspect an empty command. Update the assertions or preserve the command substring while adding the timeout.

Update the comment to match the Linux batch timeout.
scripts/ci/run-bun-test-batches.sh, Line 109 now invokes bun test --isolate --timeout 20000 for Linux shard batches. The current comment says that Linux shards use Bun's default timeout. State that Linux shard batches also use 20 seconds. State separately whether direct local bun test runs keep the default.

…ontract ci-workflows.test.ts pins the exact unsharded invocation; updating the pin keeps the timeout part of the contract so it cannot be silently dropped.
… 60s The 10s floor was still inside the observed runner stall envelope — the raised WS-terminal watchdog fired at 10.16s on the macOS lane, and the 5s sequential/tier/sideband watchdogs hit next. Watchdog floor 30s + Bun --timeout 60000 move together so neither pre-empts the other; local runs unchanged. Contract test pin follows the new lane command.

Bun test --timeout per-test timeout documentation
💡 Result:
In Bun, you can manage test timeouts at either the global level (via the command line) or the individual test level (within your code). The default timeout for all tests is 5000 milliseconds (5 seconds) [1][2][3]. Global Timeout To set a timeout globally for all tests in a run, use the --timeout flag followed by the time in milliseconds [1][2][4]. bun test --timeout 10000 # Sets a 10-second timeout for all tests Per-Test Timeout To override the default timeout for a specific test, you can pass the timeout value (in milliseconds) as the third argument to the test function [2][3]. import { test, expect } from "bun:test"; // This test will fail if it takes longer than 1 second test("my test", => { expect(1 + 1).toBe(2); }, 1000); Alternatively, you can provide an object as the third argument containing the timeout option [5]: test("my test", => { expect(1 + 1).toBe(2); }, { timeout: 1000 }); Disabling Timeout To disable the timeout for a specific test, set the timeout value to 0 or Infinity [2]. test("infinite test", async => { await someVeryLongOperation; }, 0);

Correct the timeout-ordering explanation in tests/helpers/ci-watchdog.ts:11-13.
--timeout 60000 exceeds the 30,000 ms CI watchdog floor. The watchdog fires first, and Bun’s timeout is the outer backstop. The previous 20,000 ms timeout would have fired first.
