test(llc): expand channel event handling coverage - #2942
Conversation
📝 WalkthroughWalkthroughChangesThe change adds broad channel client state test coverage for message, reaction, poll, channel, member, watcher, live location, and optional payload events. Channel client state events
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🔵 Low · up to This change expands channel event coverage without changing production behavior. It is low risk, but the remaining test gaps could allow stale poll votes, incorrect member ban state, or unintended state loss on incomplete events to go undetected.

3465-3469: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winSeed existing state in the missing-payload tests.
These listeners can run while state exists, but their null-payload branches return before mutation. The current tests only use absent state, so they cannot detect a regression that clears an existing draft, reminder, or push preference. Seed each value before dispatching the event and assert that it remains unchanged.

1614-1614: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winCover the replacement branch of
pollVoteChanged.This test starts with no cached vote, so it only checks insertion. An implementation that keeps a stale vote or appends a duplicate vote can still pass. Seed an existing current-user vote and assert that only the changed vote remains.

Depends on #2930 — merge that first. This branch is built on top of it, so until #2930 lands, the diff GitHub shows here also contains #2930's file split. Once #2930 is on
master, this PR's diff reduces to the single test file below.Replaces #2905, which could not be rebased: 100% of its diff was inside
group('WS events'), which #2930 moved out ofchannel_test.dartintochannel_client_state_test.dart.Rebased onto #2930's new layout: the moved test now lives at
test/src/client/channel/channel_client_state_test.dart.Description of the pull request
Test-only change: expands WebSocket event handling coverage in
channel_client_state_test.dart(+43 tests,stream_chatsuite goes from 1639 to 1682 tests). No production code is touched.New coverage inside the
WS eventsgroup:typing.start/typing.stopfrom other users, current-user events ignored, missing-user guards.notification.message_newadds the message and counts unread; channel messages are not appended while the channel is not up to date (thread-only replies still are); missing-message guard.reaction.new/reaction.updated/reaction.deletedupdatingownReactionson channel and thread messages.deletedForMepropagation.channel.truncatedclears messages and wipes persistence;notification.channel_truncatedkeeps the event's system message.member.added/member.removed/member.updated, non-member user events ignored, anduser.banned/user.unbannedmember refresh (including the app-level ban without cid guard).user.watching.stopwithout a watcher count preserves the count.FakeClientStategains ausersoverride (3 lines intest/src/fakes.dart) needed by the reaction and poll tests.Re-derivation from #2905
Because #2930 is a content-preserving move, this was a block swap rather than a rewrite, and that is checkable:
group('WS events')is byte-identical (3,973 lines) between test(llc): expand channel event handling coverage #2905's merge-base and refactor(llc): splitchannel.dartinto focused files #2930'schannel_client_state_test.dart— the split relocated the group without touching a line of it.channel.dartinto focused files #2930, and the group itself is byte-identical to test(llc): expand channel event handling coverage #2905's head. Thefakes.darthunk applied unchanged.No test content was rewritten, and no assertion was re-authored — the same 43 tests, in the file that now owns the code they exercise.
No CHANGELOG entry: test-only, no observable behavior change.
