## Summary This PR does two things. It updates the mobile testing conventions to favor a few journey tests over many small logic tests. It also applies those conventions to the existing mobile suite, one commit per step. ### Testing conventions (`AGENTS.md`, `mobile/README.md`) - Start with one widget journey per user-visible flow, driven through the real widgets, notifiers and coordinators. Assert what the user sees and what is durably saved. - Cover retry, cancel and resume as steps inside the journey, not as separate tests. - Fake only external boundaries (network, relay, OS, browser, storage). - Use focused, table-driven tests only for security and data-loss invariants, protocol or crypto vectors, and pure functions with many input combinations. - When review finds a defect, extend an existing journey or table instead of adding a test per finding. - Delete a lower-level test only once a journey demonstrably catches the same failures. - Every test must fail when the production code it guards is broken. These conventions keep the Review-Proven Rules' safety bar and change only how coverage is organized. ### Suite inventory and plan The suite has 234 Dart test files, about 110k lines and about 2,600 declared tests. Native tests are separate: BuzzPushKit, RunnerTests, NativeControlTests and Android. Line-saving estimates are hypotheses, not a deletion budget. Each deletion needs a replacement that rejects a representative production mutation. 1. **CI and reliability.** Run the native tests CI skipped, make time-dependent tests deterministic, and make tests that could not fail falsifiable. *(done, see below)* 2. **Shared harness.** Add one fake relay (socket plus HTTP boundary, with the real `RelaySessionNotifier`) in `test/helpers/`. Today 38 files each write their own `RelaySessionNotifier` fake. *(done, see below)* 3. **Per-area journeys.** Convert page tests that fake the flow's own notifiers (for example, `channel_detail_page_test` overrides about 60 providers). Fold near-duplicates into tables. Remove constant-pinning, pixel-geometry and call-count tests once a journey covers the outcome. Split `channel_detail_page_test.dart` (17.7k lines). Each area commit reports before/after counts and the mutation it rejects. 4. **CI speed.** Shard by file instead of by test, since every shard currently compiles the whole suite. *(done, see below)* Keep as-is: relay protocol and NIP handling, crypto vectors, auth, push security, persistence and journal invariants, recipient routing, and real-socket transport and cancellation tests. ### Step 1 changes - **Android CI** runs the 23 JVM unit tests, which were never run before. It retries the APK build once, only on SDK or plugin download failures (the cause of 4 recent `main` failures). - **iOS CI** runs all RunnerTests (previously 2 of 99) and the previously uncalled Me-agent accessibility script. The Swift Native lane builds the simulator app once, in the background while the simulator boots and runs the native-control scripts, instead of twice. The lane stays non-required. - **Stale RunnerTests.** Two reaction-details tests still expected the filter list that #8280 replaced; they now cover the toggle list. #8393 moved navigation bar controls onto a shared glass surface and made unknown Tabler symbols assert. The avatar and members-activity tests now find controls on that surface, three tests use real symbol names, and a 240 pt title width pinned to the old control sizes is removed (its gap assertions remain). - **Known bug, not fixed here.** Since #8393 the DM title avatar image is nil, because `makeItem` returns avatar data as a custom-view item. No screen passes a title avatar yet. The test marks it `XCTExpectFailure`. - **Typing retry** and **sections backoff** tests use fake time instead of about 37 s of real sleeps and a `Stopwatch < 100ms` threshold. - **Manage-channel sheet tests** previously asserted inside callbacks that the sheet's `catch (_)` swallows. A wrong saved description made the test loop until killed. The tests now record arguments, assert outside the caught code, and cancel instead of re-presenting endlessly. - **`video_viewer_transport_test` removed.** It exercised only `package:http`. Removing the production `request.sink.close()` already fails `video_viewer_test`. ### Step 2 changes - **`test/helpers/fake_relay.dart`** fakes only the websocket (through the session's socket factory) and the HTTP bridge (through its client). The real `RelaySessionNotifier` still connects from `build()`, handles OK and CLOSED, batches events, backs off and replays subscriptions. - The fake serves the NIP-CW channel window. It can hold OK and live echo independently, reject a chosen publish, and drop the connection. Any request it cannot answer faithfully fails the test at teardown, because the app often catches relay errors and falls back. - **`channel_messages_journey_test`**: history through the channel window, a live message, a send that is pending until OK and stays one row after the echo, a rejected send rolled back, then drop and reconnect with missed and later messages. - **`channel_send_journey_test`**: type and send on `ChannelDetailPage` with no feature-notifier overrides. The row and sending spinner show at once, OK settles them, and a rejected send puts the text back in the composer and shows a snackbar. - Existing per-file relay fakes and `SidebarRelay` are unchanged. Step 3 migrates them area by area. ### Step 4 changes - `scripts/mobile-test-shard.sh` splits the 235 test files across the 3 shards, balanced by line count. `flutter test --total-shards` split tests, so each shard compiled and loaded every file. Locally at 4 workers, one shard took 63 s instead of 73 s and used 40% less CPU. `channel_detail_page_test.dart` (17.7k lines) is now the long pole; splitting it in step 3 shortens the slowest shard. Out of scope here: requiring branches to be up to date before merge (a repository setting), and the onboarding tests in #8375. ## Validation - Mutation checks: - Typing retry bound: test fails. - Sections backoff reset: test fails. - Wrong saved description: fails in about 11 s. The old tests hung instead. - Removed sink close: `video_viewer_test` fails. - Changed Dart files pass locally, and `flutter analyze` is clean. - Android `testDebugUnitTest` passes locally (23 tests). The Me-agent accessibility script passes on a local simulator. - Step 2 mutation checks, each made a journey fail: accepted OK ignored, rejected row not rolled back, optimistic row not added, draft not restored, local message left pending after OK, channel window replaced by the fallback, live subscriptions not replayed after reconnect. - Both journeys run in about 1 s on fake time. - All 99 RunnerTests pass on an iPhone 16 iOS 26.5 simulator, the CI destination, after rebasing on #8398. - The shard script partitions all 235 test files exactly once. 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: Wes <wesbillman@users.noreply.github.com> Co-authored-by: Carl <32a2e2c9d428ee08902cab75d956da2c1d235a22d4766b0dd4138bf6e2e5db1d@buzz.block.builderlab.xyz> Co-authored-by: Claude Opus 5.5 <noreply@anthropic.com>
Buzz Mobile
Flutter mobile client for Buzz.
See VISION_MOBILE.md for intended behavior and architecture.
Optional Builderlab login
BUZZ_AUTH_DOMAINS is a comma-separated build-time environment setting, passed
with Flutter's --dart-define (shell environment variables alone are not read):
flutter run --dart-define=BUZZ_AUTH_DOMAINS=communities.buzz.xyz,communities.public.builderlabstaging.xyz
Unset or empty means Builderlab features are disabled: no account login, community creation, backup/recovery UI, reconnect prompts, or background account restoration. QR/code pairing, community links and invites use Nostr-only entry. Saved account keys and sessions are retained for a later enabled build.
A nonempty list enables Builderlab features and requires account setup only for
matching domains. Those features need their backend endpoints. Normal relay key
authentication remains in place. BUZZ_BUILDERLAB_URL selects the backend; setting
it alone does not enable Builderlab features.
Entries match the domain itself and its subdomains, case-insensitively. Use DNS
names, not URLs or wildcards. The list does not add trusted account servers:
configured domains outside the supported Builderlab realm cannot use hosted
setup. BUZZ_BUILDERLAB_URL still selects the trusted account environment.
Hosted relay authentication
--dart-define=BUZZ_HOSTED_RELAY_AUTH=true enables Builderlab relay assertions
and reconnect sign-in only for BUZZ_AUTH_DOMAINS matches. It defaults off: configure backend assertion issuance
before enabling mobile authentication, and enable relay enforcement last.
Setup
Use the Flutter SDK pinned by the repository. Activate Hermit from the repo root before resolving packages or running any Flutter command:
cd /path/to/buzz
. ./bin/activate-hermit
./bin/just mobile-install
mobile-build-android intentionally builds with --no-pub. If an IDE or an
external Flutter SDK has touched mobile/.dart_tool, rerun mobile-install
with the pinned SDK before building so flutter_test, sky_engine, and the
engine all come from the same Flutter version.
iOS toolchain
Use Xcode 27.0 for iOS development and build validation on an Apple silicon Mac running macOS Tahoe 26.6 or later, as required by the Xcode 27 release notes. On Intel Macs or hosts that cannot meet those requirements, use a compatible Xcode 26 version, which remains supported. Activate the repository's pinned Flutter SDK with Hermit as described above.
When multiple Xcode versions are installed, select the intended version for
the command with DEVELOPER_DIR, for example:
DEVELOPER_DIR=/Applications/Xcode-27.0.0.app/Contents/Developer xcodebuild -version
Adjust the path to your installation. Keep the compiler and SDK from the same
Xcode installation. The pinned Flutter native-assets tooling can discover the
globally selected SDK even when DEVELOPER_DIR selects another compiler, so
use a build machine with a matching default Xcode when validating either
Xcode 26 or Xcode 27.
The native cryptography dependency is pinned upstream C source in
ios/BuzzPushKit/Sources/CSecp256k1; it requires no Swift build-plugin approval.
GitHub's mobile CI currently uses the Xcode default of its macos-latest
runner. The internal release toolchain is configured separately in
buzz-releases.
Run
# From repo root (applies a worktree-isolated debug identity and starts/reuses Simulator):
just mobile-dev
# Direct (uses the app's configured community; apply worktree overrides first):
cd mobile && flutter run --dart-define=BUZZ_PUSH_GATEWAY_URL=https://push.example
Worktree-aware debug identity
Debug builds produced from a git worktree get a unique app identifier keyed
to the worktree directory name
(xyz.block.buzz.dev.mobile.<slug> on iOS,
xyz.block.buzz.mobile.<slug> on Android) plus a display-only branch label
in the app name (Buzz (my-branch), or a short SHA when the worktree is
detached). Because the identifier follows the directory rather than the
branch, one worktree keeps exactly one installed app — and its login state —
across branch switches, and builds from multiple worktrees install side by
side, mirroring the desktop dev experience. Release and profile builds
always keep the production identity and name.
just mobile-dev and just mobile-build-android apply this automatically by
running scripts/mobile-worktree-overrides.sh, which writes two gitignored
files:
mobile/ios/Flutter/WorktreeOverrides.xcconfig(included by Debug builds only; a developer'sAppOverrides.xcconfigis included after it, so app-specific overrides like a personalBUNDLE_IDENTIFIERfor device signing always win)mobile/android/worktree.properties(read by the debug build type only)
Android developers can keep a stable local test identity that takes precedence
over the generated worktree values by creating the gitignored
mobile/android/AppOverrides.properties:
appName=Buzz Pairing
applicationIdSuffix=.device_pairing_e2e1
These values are consumed by the debug build type only. The standard
just mobile-build-android command can still be used; regenerating
worktree.properties does not overwrite AppOverrides.properties. Release
and profile builds keep the production Buzz name and application ID.
For direct Xcode / Android Studio / flutter run development, run
./scripts/mobile-worktree-overrides.sh from the repo root once per branch
switch to refresh the display label (the install identity never changes);
the persisted files are then picked up by any subsequent build. In the main
checkout the script is a no-op that removes stale override files, restoring
the plain Buzz identity. To enable push in direct Xcode builds and Runner tests, supply a
BUZZ_PUSH_GATEWAY_URL build setting in the gitignored
mobile/ios/Flutter/AppOverrides.xcconfig; the build phase validates and
passes it through as a Flutter Dart define. Since // begins an xcconfig
comment, spell the origin as BUZZ_PUSH_GATEWAY_URL = https:/$()/push.example.
For an Android debug build that must remain installed alongside other Buzz worktree builds, set an explicit launcher name and package suffix when invoking the generator or a recipe that invokes it:
BUZZ_PUSH_GATEWAY_URL="https://push.example" \
BUZZ_ANDROID_DEBUG_APP_NAME="Buzz Huddles" \
BUZZ_ANDROID_DEBUG_ID_SUFFIX=".huddles_829c" \
./bin/just mobile-build-android
This example produces the debug-only package
xyz.block.buzz.mobile.huddles_829c with the launcher label Buzz Huddles.
The suffix must start with a dot followed by a lowercase letter and may contain
only lowercase letters, digits, and underscores. Release and profile builds
ignore these overrides and retain the production package and name.
To remove leftover worktree-suffixed installs from booted iOS simulators and
connected Android emulators, run just mobile-clean (add --dry-run via
./scripts/mobile-worktree-clean.sh --dry-run to preview). Production
installs are never touched.
iOS push capability
Every iOS artifact builds and embeds the Notification Service Extension and
native push bridge. Runtime activation is fail-closed and scoped to the current
relay. After authenticated connectivity and a fully valid NIP-11 buzz-push-v1 push
descriptor, Buzz independently requests display permission and registers with
APNs. Display denial or request failure does not gate the device token, gateway
enrollment, or lease publication, so a later user opt-in can display pushes
without rebuilding transport authority. An absent, malformed, or unreachable
descriptor leaves push inactive without partial enrollment.
Mobile builds without a gateway origin succeed with push unavailable. To enable push, supply the gateway origin explicitly:
flutter build ios --dart-define=BUZZ_PUSH_GATEWAY_URL=https://push.example
flutter build apk --dart-define=BUZZ_PUSH_GATEWAY_URL=https://push.example
The iOS and Android build gates validate any supplied define, rejecting empty or malformed values. Release/profile builds require an HTTPS origin without an explicit port. An absent define disables permission requests, APNs registration, gateway enrollment, and lease publication; Settings shows push as unavailable. No production gateway is selected implicitly. Enrollment grants and crash-recovery journals are scoped to this origin. Push has not shipped to existing users, so there is no legacy-state or cross-gateway migration. Changing gateways requires fresh enrollment; old installations expire under their original gateway's lease policy. Current-gateway response loss is still retried from the exact journaled request.
Relay rollout remains an explicit deployment opt-in. Only deployments with
BUZZ_PUSH_ENABLED=true advertise the descriptor and process push. See
docs/push-gateway-deployment.md for the canonical gateway profile contract,
manual physical-device proof, measurements, and rollback procedure.
For local physical-device development, override the identity and sandbox
environments in the gitignored mobile/ios/Flutter/AppOverrides.xcconfig:
BUNDLE_IDENTIFIER = com.example.buzz.mobile
BUZZ_DEVELOPMENT_TEAM = YOUR_TEAM_ID
BUZZ_IOS_PUSH_ENVIRONMENT = development
BUZZ_APP_ATTEST_ENVIRONMENT = development
BUZZ_PUSH_GATEWAY_URL = https:/$()/push.example
Use your personal bundle ID and team above. Provision both the parent and its
.NotificationService extension. Configure an isolated gateway with the matching
App Attest application ID, APNs topic and sandbox certificate. Development
attestation requires the explicit personal-dev-app-attest gateway build feature
and BUZZ_PUSH_APP_ATTEST_ENVIRONMENT=development; ordinary gateway builds accept
production attestation only. See docs/push-gateway-deployment.md.
Validate distributed builds separately using a signed release candidate and
its matching gateway configuration.
Parent app identifiers require Apple's Communication Notifications capability and a regenerated app provisioning profile. The Notification Service Extension profile does not require that capability. Enable it on the personal development App ID for local rich-presentation validation. Enabling it on distribution App IDs is a release follow-up and is not performed by this repository change. Without a matching parent profile, source and unit validation still work, but the app cannot be signed for a physical device.
APNs and the gateway continue to carry only the constant opaque wake-up. The extension fetches the message from the scoped relay, verifies message, sender profile, and channel-metadata signatures, and uses a bounded App Group cache for names and app-rendered avatar thumbnails. It never fetches an avatar URL; missing, stale, or invalid enrichment falls back to the verified message with a short sender pubkey, community subtitle, and no image.
Checks
dart format --output=none --set-exit-if-changed .
flutter analyze
flutter test --dart-define=BUZZ_PUSH_GATEWAY_URL=https://push.example
Or from the repo root: just mobile-check and just mobile-test.
When writing tests, favor a few journey tests that drive real user flows over many small logic tests. See Testing Conventions.
Android release signing
Android release builds fail unless all upload-key inputs are supplied through the environment:
BUZZ_ANDROID_UPLOAD_KEYSTORE_PATH: path to a CI-vended keystore fileBUZZ_ANDROID_UPLOAD_KEYSTORE_PASSWORDBUZZ_ANDROID_UPLOAD_KEY_ALIASBUZZ_ANDROID_UPLOAD_KEY_PASSWORD
The keystore path must be absolute, and the keystore must remain outside the repository. Development and debug builds do not require these variables.
Release pipelines that sign through the central APK Signer service instead of
a local upload keystore must set BUZZ_ANDROID_RELEASE_SIGNING=external. That
mode produces an unsigned release bundle and refuses to run if any
BUZZ_ANDROID_UPLOAD_* value is also set.
