Go 1.25's testing/synctest package (GA) provides a fake clock bubble
for deterministic goroutine and timer testing. Convert tests that
waited on real-time durations to use synctest, removing most wall-clock
time.Sleep workarounds.
Converted (11 tests, 9 files):
- notify/notify_test.go — all tests, replaced 17 time.Sleep(110ms) with synctest.Wait()
- store/service/service_test.go — VoteSameIPWithDuration, UserReplies, submitImages,
ResubmitStagingImages, deleteImagesOnCommentDelete
- store/image/{image,bolt_store}_test.go — Cleanup, Submit, SubmitDelay
- store/engine/bolt_test.go — FlagListBlocked
- providers/telegram_test.go — DispatchTelegramUpdates
- migrator/backup_test.go — TestBackup_Do
- _example/memory_store/accessor/data_test.go — FlagListBlocked
Simplifications along the way:
- notify/notify_mock.go: dropped the 10ms time.After delay and
ctx.Done select in MockDest — the artificial I/O simulation is
pointless and blocked synctest.Wait from draining the queue
- Removed three dead-code time.Sleep(1s) calls in EditCommentDurationFailed,
EditCommentAdmin, and Info tests: prepopulated comments from 2017
already exceed any EditDuration/ReadOnlyAge under real clock, making
the sleeps meaningless
- UserReplies: replaced the Eventually+Sleep+mutex polling with a
direct time.Sleep under fake clock
Skipped (incompatible with synctest):
- fs_store_test.go: relies on OS file mtime (real wall clock)
- rss_test.go: needs real wall-clock second boundary for pubDate
- admin/rest_private/rest_public tests: httptest network I/O
- cmd/server_test.go: real HTTP server startup polling
Notes on quirks encountered:
- synctest.Wait() does NOT advance fake time, contrary to what one
might expect. It only returns once all other bubble goroutines are
durably blocked. To advance the fake clock, the test goroutine must
itself call time.Sleep
- BoltDB keys the "last" bucket by comment.Timestamp nanosecond string.
Rapid b.Create calls under frozen fake time produce identical keys
and overwrite each other. TestService_UserReplies adds
time.Sleep(time.Nanosecond) between Creates to advance the clock
- Bolt image Cleanup uses strict age > ttl. Under fake time the
age-ttl delta is exactly zero at the boundary, so subtract 1ms from
the passed ttl to stay strictly under
