All six tests had been silently skipped under @Tags(['drift']) for
6+ months, so they accumulated test-vs-implementation drift. Now
running against the libsqlite3-bearing ci-flutter:3.44 image, each
failed for a distinct reason. Diagnoses below.
audio_cache_manager_test 'usageBytes sums sizeBytes across rows':
usageBytes() is a directory walk (authoritative on-disk total,
catches orphan partials the index misses). The test inserted drift
rows but never wrote files, so the walk returned 0. The actual API
for summing drift sizeBytes is bucketUsage(). Rename to
'bucketUsage sums drift sizeBytes across rows', use that API,
assert liked+rolling == 350. Also give the two rows unique paths
per row-shape sanity.
sync_controller_test (3 200-path tests, all returning null result):
Map literals in Dart 3 with mixed value types infer as
Map<String, Object>, not Map<String, dynamic>. The sync controller
casts `resp.data as Map<String, dynamic>` (and several nested
casts), which is invariant on generics and throws TypeError. The
silent try/catch in sync() swallowed the throw and returned null.
Real JSON parsing produces Map<String, dynamic>, so this never
surfaced in production. Fix: route the test stub body through
jsonDecode(jsonEncode(body)) in _stubDio — mimics real Dio's
parsed-response shape. Affects '200 with artist upsert', '200 with
track delete', and 'like_track upsert + delete round-trip'.
quarantine_provider_test 'flag keeps drift optimistic + queues
mutation on server failure':
When the API stub throws, the controller catches + queues to
CachedMutations. The drift watch() stream in MyQuarantineController
was still in loading state when addTearDown disposed the
container, tripping Riverpod's "StreamProvider disposed during
loading" assertion. The success-path tests resolved before
tearDown so they didn't see it. Fix: await one microtask before
the test ends so the stream emits.
like_button_test 'tap toggles icon optimistically; rollback on error':
After the LikeButton was migrated to LucideHeart in the Lucide
sweep, the prior fix replaced the find.byIcon assertion with a
heartFilled() helper reading LucideHeart.filled. But likesController
.toggle() goes through an async chain (optimistic state flip + await
api.like + state notification), which one frame of tester.pump()
doesn't flush. Use pumpAndSettle after both tap and rollback toggle
so the widget rebuilds with the new state before the assertion.
After this push, the drift cohort should be all-green on the
libsqlite3-bearing image. Fable #399 / local #62.
