Problem

The tests in generateWrapper with migrations bundle Workers and start workerd through Miniflare. Many also start PGlite or a fake MySQL server. On Windows CI runners, disk and process start can stall. Then one of these tests can pass the 20-second unit timeout that Windows uses.

Slowest test in this file, 16 Windows unit runs on main (2026-10-14 to 2026-10-15):

seconds   0    5    10   15   20 (timeout)
          |----|----|----|----|
1.9-4.9   ##                       8 runs
6.5-7.7   ####                     2 runs
8.0-9.5   #####                    4 runs   pg bundle (3), @schema folder (1)
14.4      ########                 1 run    @schema folder
20.1      ##########X              1 run    PostgreSQL cron -> FAIL (run 38639851975)

In that failed run, the file took 82.6 s and a neighbor test took 15.9 s. In 6 of 16 runs the slowest test took 8 s or more.

PR #435 (run 38700489787) also failed in this describe: bundles the mysql2 dependencies that sit in the app node_modules passed 20 s. On main it takes 0.7-2.3 s. In that period, unrelated tests on the same runner were 3-10x slower too.

Per test on main (16 runs):

Test	Median	Max	Runs at 8 s or more
gives a PostgreSQL cron the app database and schema in workerd	3.3 s	20.1 s (timeout)	1
bundles @void/deploy-core when it sits in the app node_modules	1.1 s	15.9 s	1
gives a cron a schema folder through @Schema	2.5 s	14.4 s	3
bundles the pg dependencies that sit in the app node_modules	3.4 s	9.0 s	4
runs a MySQL cron event and queue batch on one connection each	2.7 s	9.0 s	1
runs a PostgreSQL cron event and queue batch on one connection each	4.1 s	7.0 s	0
starts a PostgreSQL cron Worker at a compatibility date without node:fs	2.6 s	6.3 s	0
gives a MySQL cron the app database and schema in workerd	1.7 s	6.0 s	0

All tests that reach 8 s or more are in this describe. Tests in other describes of this file stay under 1 s on main.

Decisions

Decision	Reason
Set timeout on the generateWrapper with migrations describe	All the slow tests are in this describe. One option covers them without a change to each test.
60 s on Windows only	This is 3x the 20 s limit, which covers the 3-10x runner slowdowns that we saw. Other platforms keep the default. This is the same form as other slow Windows tests in the repo.
No change to vite.config.ts or the global testTimeout	Other unit tests keep the 20 s limit, so a real hang there still fails fast.
No change to test logic	The tests pass when the runner is not stalled. The problem is the time budget, not the behavior.

Known limits

• This does not make the tests faster. On a slow Windows runner the file can still take more than 80 s.
• If a runner stalls for more than 60 s in one test, the test still fails.
• The fast tests in this describe also get the 60 s budget on Windows. They do not need it, but a real hang in one of them takes longer to report.
• The beforeAll hook that prepares PGlite keeps its own 30 s Windows budget.

Testing

Check	Result
vp test run packages/void/test/unit/wrapper.test.ts (macOS)	34 passed, 3.3 s
Describe option reaches each test (temporary check, not committed)	Test timeout is 60,000 ms with the option set and 5,000 ms with undefined
vp lint --no-ignore on the file	Pass
vp fmt check on the file	No changes
Windows CI	Label test: windows added
