Each selector in the chain is matched within the descendants of the
previous match. Returns the deepest match (or nil) for FindBySelectorPath
and every deepest match for FindAllBySelectorPath.
The previous snippet referenced `state.ax.find` inside an actions()
body where state is not in scope, and shadowed the imported actions
helper with an export of the same name.
Math.random() breaks --seed reproducibility. The verifier's seeded
RNG flows through from(), so re-running a seed now produces the
same card pick sequence.
Now that ResourceID populates uniformly across Android/iOS Compose,
the spec can read element.id directly instead of probing attrs for
each platform's underlying field name.
iOS Compose surfaces testTag as accessibilityIdentifier. Previously
only resource-id and identifier seeded element.ResourceID, leaving
element.id empty for iOS Compose nodes and forcing specs to walk
attrs to recover stable identifiers.
Extractor previous/current advance only on PushSnapshot, never per
thunk-call. refreshPredicateErrors depends on this for safe re-entry.
Also flags that re-invoked predicates run outside their LTL gate, so
they must be side-effect-free reads.
Drops the silent in-memory fallback. The README claims OPFS
persistence; falling back without surfacing the degrade made data
loss invisible across reloads. Now the worker errors out and the
Kotlin DriverFactory rejects the create() call instead.
Read repository.session.value at first composition and pick
Route.Home or Route.Login as the NavHost startDestination. Avoids
the one-frame Home flash on cold start with no persisted session.
Replaces string-heuristic identity in the spec extractors with stable
testTags. AccountCard exposes AccountName; LedgerRow exposes TxnNote
and TxnDate. Spec extractors read those directly instead of filtering
visible text by "starts with $" / "matches digit".
Match KotlinConf-app's filesystem layout where every entry point (android,
ios, web, shared, ui-components) lives under app/. iosApp is still an Xcode
project, not a Gradle module, so settings.gradle.kts is unchanged.
webpack-dev-server now binds 8088 (or WEBAPP_PORT) so it doesn't
collide with the docs server on 8080. Drop the per-message reply
log; keep only the OPFS init line and error logging.
Wasm SqlDriver doesn't auto-track user_version like the Android
driver, so awaitCreate() ran on every page load and tripped over
already-created tables. Read PRAGMA user_version, run
awaitCreate/awaitMigrate based on it, and self-heal pre-existing
tables with version 0 by stamping the current schema version.
sqlite.worker.js implements the SQLDelight web-worker protocol
(exec/begin_transaction/end_transaction/rollback_transaction) on top
of @sqlite.org/sqlite-wasm. Prefers the OPFS SAH pool VFS for
persistent storage and falls back to in-memory when OPFS is
unavailable.
webpack.config.d/coopcoep.js sends COOP/COEP headers on the dev
server so cross-origin isolation is available, even though the SAH
pool itself does not require it. webpack.config.d/sqlite-wasm.js
enables asyncWebAssembly so webpack can bundle sqlite3.wasm via the
'new URL("sqlite3.wasm", import.meta.url)' reference inside the
sqlite-wasm package.
main.kt mirrors the iOS entry point: builds DriverFactory + AppGraph
factory, hooks browser back-gesture into WebBackGesture, then mounts
the shared App composable into ComposeViewport.
Compose Multiplatform target that depends on :app:shared and pulls
@sqlite.org/sqlite-wasm 3.53.0-build1 as the npm runtime for the
SQLDelight web worker.
org.w3c.dom.Worker on wasmJs lives in kotlinx-browser, not the stdlib.
Pin 0.5.0 alongside the @sqlite.org/sqlite-wasm 3.53.0-build1 version
that the upcoming web app will depend on, and switch the worker
constructor to the module-worker form that webpack expects.
Wraps androidx.navigation.NavHostController behind the existing
push/replace/back surface so call sites in ViewModels stay unchanged.
App.kt now wires a typed NavHost with @Serializable Route entries
and observes the controller's currentBackStackEntry to drive the
session-based Login/Home redirect.
Adds the JetBrains KMP navigation-compose library to the shared
module. Used in subsequent commits to replace the hand-rolled
Navigator with a typed-route NavHost.
MainActivity (Android) and MainViewController (iOS) now own the
suspend DriverFactory.create() and feed the resulting LedgerDatabase
into Metro's createGraphFactory<AppGraph.Factory>().
App now takes a suspend graph builder; the platform constructs
LedgerDatabase off the suspend DriverFactory.create() before invoking
the Metro graph factory. Routes resolve VMs through LocalAppGraph
instead of the hand-rolled LocalAppComponent.
Drops the loading-state placeholder comment (the empty Box is enough).
Compose's androidx.compose.ui.semantics.testTagsAsResourceId is
Android-only. Calling it directly from commonMain broke
linkDebugFrameworkIosSimulatorArm64. Replace with an expect Modifier
extension that wires the semantics on Android and is a no-op on
iOS / wasmJs.
Single shared @DependencyGraph(AppScope::class) that exposes
Repository, Navigator, and ViewModels. LedgerDatabase enters the
graph via @DependencyGraph.Factory.create(database) so the suspend
DriverFactory.create() can stay outside the DI surface.
@Binds wires SqlLedgerStore to LedgerStore; Navigator is provided
explicitly so its Route.Home start state stays in DI rather than
relying on a default-parameter being honored by the graph.
LedgerViewModel and AddTransactionViewModel use @AssistedInject for
their accountId param plus a nested @AssistedFactory; the rest are
plain @Inject constructor classes.
EvaluateProperties short-circuits once an Always-property latches to
violated, so the underlying goja predicate stops being called and
formula.err keeps whatever it threw at step 1. The runner logs
PredicateError every step a property is violated, which made every
subsequent log line repeat the step-1 throw. That looks like the spec
runtime is seeing stale state, but it is just stale error reporting.
EvaluateProperties now invokes every registered predicate once per step
purely to refresh formula.err. Verdicts are unaffected. The thunk
itself stops latching so the new value wins on whichever path runs first.
The runner logs PredicateError once per step. The current implementation
latches the first error per thunk, so the log freezes on step 1 forever
even when later steps would observe different errors. This test fails
today and locks in the contract: PredicateError must reflect the most
recent step.
App.kt sets testTagsAsResourceId=true on the root Box semantics so
Compose's testTag surfaces as Android resource-id (and equivalent on
iOS via accessibilityIdentifier). Without this, testTag stays in the
Compose semantics tree but never reaches the runtime hierarchy that
UIAutomator and Sanderling read.
Also adds TestStateAxObjectSelectorTestTagAlias as a regression
test for the {testTag: ...} object selector resolving through the
SDK alias to resource-id at the JS bridge layer.
- Drop ksp/metro/navigation3 plugin aliases - not actually applied
by any module in this PR (deferred follow-up).
- import awaitAsOne from app.cash.sqldelight.async.coroutines for
the suspend single-row reads enabled by generateAsync = true.
- Drop kotlin.js.ExperimentalWasmJsInterop opt-in from common
compilerOptions (it isn't valid for android/jvm targets).
- :app:shared androidMain pulls in androidx.activity:activity-compose
for the BackHandler actual.
Replaces every accessibilityText / descPrefix data-carrier read with
testTag selectors that resolve to resource-id (Android) or
accessibilityIdentifier (iOS) via the SDK's alias table.
- Routes detected via testTag (LoginScreen, HomeScreen, etc.)
- Account identity = visible account name (no synthetic id encoded
in semantics).
- Ledger row identity = joined text content of the row.
- Active account derived from route alone (not parsed from
contentDescription).
- Focused input read from native focused="true" attribute, not from
a custom focused_input data carrier.
Split the monolithic :composeApp into :core, :app:shared,
:app:ui-components, and :app:androidApp. The old module is still
present and remains the source of truth until the next commits remove
it; both compile in parallel to keep iOS/Android builds green during
the cut-over.
Highlights:
- :core - SQLDelight schema + LedgerStore + Repository (now an
injectable class, not a singleton object). Methods are suspend to
match generateAsync = true.
- :app:ui-components - design system primitives. IconButton/AppButton
APIs revised: label = real contentDescription, testTag = stable
selector. Drops the data-carrier description argument.
- :app:shared - per-screen ViewModels colocated with screens; pure
composables on (state, onEvent); LocalAppComponent CompositionLocal
for hand-rolled DI; @Serializable Route. Hosts the iOS framework
(baseName Shared).
- :app:androidApp - thin Android entry that constructs the
DriverFactory and hands it to App().
- gradle/libs.versions.toml centralises versions; settings.gradle.kts
enables type-safe project accessors.
Deferred to follow-up PRs (per the design discussion):
- Metro DI: hand-rolled AppComponent for now; Metro graphs are mostly
ceremony for an app this size and add KSP/version risk.
- Navigation3: kept the existing Navigator-as-backstack class,
injected rather than singleton; nav3 isn't shipping a stable
multiplatform artifact for commonMain consumption yet.
- :app:webApp + OPFS sqlite worker: web persistence is real new
wiring (custom worker on @sqlite.org/sqlite-wasm). Master's
WebLedgerStore + Snapshot is being removed by this PR; web stays
buildable as a klib but no app-level wasm binary lands here.
Centralises versions for all folio modules ahead of the module split.
Adds new entries for kotlinx-serialization, navigation3, Metro, KSP,
and the JetBrains lifecycle-viewmodel-compose multiplatform artifact.
Compose's testTag surfaces as resource-id on Android and as
accessibilityIdentifier on iOS. Selectors written as
{ testTag: "Foo" } now match either, so Sanderling specs can use the
same tag on both platforms.
Also rounds out the iOS identifier aliases so resource-id /
identifier / accessibilityIdentifier all resolve to one another.

* feat(hierarchy): full-attribute selector system
- Add Attributes map to Element (raw platform attrs + serialized booleans)
- Add Selector / AttrFilter types for multi-filter AND matching
- Add matchAttr with alias expansion and substring/boolean semantics
- Add matchSelector (AND of all filters)
- id: and desc: keep exact/suffix/prefix semantics for backward compat
- text: widens to substring via matchAttr
- default: case routes unknown kinds to matchAttr (NEW)
- Add Tree.FindNode / Tree.FindAllNodes returning *Node
- Add Node.Find / Node.FindAll for scoped subtree string search
- Add Node.FindBySelector / Node.FindAllBySelector for object AND search
- Add attributeAliases for cross-platform name expansion
* test(hierarchy): full-attribute selector coverage
- raw resource-id: substring match
- label:/content-desc: alias expansion to accessibilityText on iOS
- scrollable:true/false boolean exact match
- title: iOS-only attribute, graceful nil on Android
- text: substring widening
- Selector AND: both filters must match; single miss returns nil
- Node.Find scoped search: descendants only, not siblings
* feat(verifier): object-form selectors + attrs + element-level find
- ax.find/findAll accept string or {attr:value} JS objects
- Object form builds Selector with AND semantics
- Returned element objects expose attrs sub-object (raw platform attrs)
- Returned element objects expose .find() and .findAll() scoped to subtree
- Element-level .find/.findAll accept string or object selectors
* feat(spec): extend AccessibilityElement and AccessibilityTree types
- AccessibilityElement gains attrs, find(), findAll()
- find/findAll on both Tree and Element accept string | AttrSelector
- AttrSelector = Record<string, string> for object-form AND matching
* feat(folio): migrate to chained object-form selectors
- Replace path queries (desc:X > desc:Y) with chained API
- Screen root lookups use { accessibilityText: "ScreenName" }
- Element-scoped searches use find/findAll with string or object
- Keep string selectors for descPrefix: and desc:Back (shows both forms)

* fix(folio): detect screens from unique element presence, not id: selectors
testTag() in Compose is not exposed as resource-id without testTagsAsResourceId.
Use desc: selectors for elements unique to each screen instead of id: path queries.
* feat(folio): add screen root contentDescription for scoped ax selection
Each screen root gets semantics { contentDescription = "ScreenName" } so
sanderling specs can scope element lookups through the screen: desc:LoginScreen > desc:login_submit.
* fix(folio): scope all ax selectors through screen root nodes
Use desc:ScreenName > desc:element path queries so every selector is
rooted at the screen level. focusedInput stays unscoped since it lives
in the app root, outside any screen.
* fix(folio): guard newAccountBalanceIsZero against navigation false positives
Scoped selectors return [] when not on HomeScreen so accounts vanish and
reappear as apparently-new on each visit. Skip the check when prev was empty.
* chore(folio): link @sanderling/spec to local pkg/spec for IDE type checking
* feat(spec): add desc, class, clickable, enabled, checked, focused, selected to AccessibilityElement
Runtime fields set by the verifier were missing from the TypeScript type,
causing linting errors on el.desc and related accesses in specs.
* chore(folio): switch to bun, add tsconfig.json for IDE type checking
- Remove package-lock.json, add bun.lock
- Add tsconfig.json so VSCode resolves @sanderling/spec types
- Fix parseAccount/parseLedgerRow to accept string | undefined
* feat(hierarchy): add Node tree + path query support
Preserve parent-child relationships in a Node tree at parse time.
Extend Find/FindAll with " > " path operator for scoped queries,
e.g. id:LoginScreen > desc:EmailInput.
Flat Elements slice and all public signatures unchanged.
* test(hierarchy): add path query tests
Cover single-level, multi-level, mixed-type, not-found, wrong-subtree,
and FindAll across multiple roots.

* feat(folio): testTag LoginScreen
* feat(folio): testTag HomeScreen
* feat(folio): testTag AddAccountScreen
* feat(folio): testTag LedgerScreen
* feat(folio): testTag AddTransactionScreen
* feat(folio): scope spec selectors to screen testTags via path queries
* fix(sidecar): align grpc-netty/grpc-okhttp with grpc-core version
Maestro 1.40.0 brings grpc-netty:1.50.2 which compiled against
AbstractManagedChannelImplBuilder, removed in grpc-core 1.64+.
Gradle was upgrading grpc-core to 1.68.0 while leaving grpc-netty at
1.50.2, causing NoClassDefFoundError at startup.
Force grpc-netty and grpc-okhttp to match grpcVersion so all gRPC
artifacts are binary-compatible.
* fix(sidecar): use ephemeral host port for AndroidDriver
Hard-coded port 7001 caused TcpForwarder.start() to fail with
TimeoutException when a previous sidecar process held the port open.
Pick a free port via ServerSocket(0) instead.
* chore(sidecar): bump maestro to 2.4.0, exclude graalvm from fat JAR
Maestro 2.4.0 still ships grpc-netty:1.50.2 so the grpc transport
resolution strategy is kept. GraalVM JS is excluded: unused by our
sidecar and causes shadow JAR expansion errors (pom treated as zip).
* fix(sidecar): update AndroidDriver calls for Maestro 2.4.0 API
launchApp no longer accepts a UUID argument. Third constructor param
changed from hostname to emulatorName so drop the "localhost" value.
* feat(ios): add simulator management package
* feat(testrun): add iOS platform path (simctl launch + direct TCP)
* feat(cli): add --ios-device flag and IosDevice option
* feat(sdk-ios): add Kotlin Native iOS SDK (TCP agent + POSIX socket + dispatch pauser)
* feat(folio-ios): wire SanderlingIos.start() in MainViewController
* feat(folio-ios): add test-ios justfile recipe
* fix(sdk-ios): remove unavailable C macros; manual byte swap + no-cast warnings
* fix(testrun): simctl-first launch order for iOS; Maestro init after SDK connects
* feat(proto): add env map to LaunchRequest
* feat(driver): add env param to Launch interface + all implementations
* feat(testrun): launch iOS app via XCTest with env vars instead of simctl
* feat(sidecar): add IosDriverBackend using Maestro IOSDriver + env pass-through
* feat(sidecar): wire env map in DriverService + IosDriverBackend in Main
* fix(sidecar): use LocalIOSDevice (WDA+simctl) + stop before relaunch
* fix(sidecar): include exception type in gRPC error description
* fix(sidecar): pick free WDA port instead of hardcoded 9100
Use SocketUtils.nextFreePort to pick a free port in the 22000-23000 range
rather than hardcoding 9100, which only worked if a previous WDA session
left a listener there.
* fix(sdk-ios): check semaphore wait result and throw on snapshot timeout
dispatch_semaphore_wait returns nonzero on timeout; ignoring the return
value caused pauseAndSnapshot to silently return an empty map, sending a
garbage empty STATE frame to the host. Now throws so the agent loop
reconnects instead.
* fix(folio-ios): register snapshot extractors before starting agent
SanderlingIos.start() was called before the snapshot objects were
initialized, so a PAUSE message arriving early produced an empty snapshot.
Move start() to after all extractors are registered.
* chore(ios): remove dead LaunchApp function
LaunchApp had no callers since bff3a49 switched iOS launch to go through
the sidecar driver. Remove the dead code and unused os import.
* test(ios): add unit tests for pickSimulator and iOS flag parsing
Tests for all pickSimulator branches (by name, by UDID, unknown, empty
list, iPhone preference, fallback to first). Also tests BootedUDID on a
canceled context and verifies --platform ios and --ios-device flags are
accepted by parseTestArgs.
* fix(ios): propagate error from BootedUDID instead of silently swallowing
* fix(sidecar): IosDriverBackend.healthy() returns true; WDA liveness checked in open()
* fix(sidecar): warm up WDA after health check to absorb startup race
* fix(runner): surface clear message on WDA connection drop
* docs(testrun): note WDA warmup location above WaitForHealth
* fix(sidecar): extract warmup + add one-shot WDA reconnect on IOException
* fix(runner): fatal on permanent WDA drop during hierarchy fetch
* fix(sidecar): walk cause chain in withReconnect to catch Maestro-wrapped IOException
* fix(sidecar): explicit Unit return in pressKey and waitForIdle withReconnect lambdas
* fix(sidecar): serialize WDA reconnect with ReentrantLock to prevent concurrent xcodebuild races
* fix web examples package config
* Revert "fix web examples package config"
This reverts commit 70c10ade27.
* chore: gitignore built sanderling binary
* fix(hierarchy): parse iOS [x1,y1][x2,y2] bounds + match iOS merged desc labels
* refactor(folio-spec): replace bloated spec with two focused properties
Login is opportunistic. Two concrete properties:
1. every new account starts with balance 0
2. every new txn changes ledger balance by exactly its signed amount
Actions: directed login -> addAccount -> addTxn -> back weighted flow.
* feat(proto): add env map to LaunchRequest
* feat(driver): add env param to Launch interface and all implementations
* feat(sidecar): add IosDriverBackend using Maestro IOSDriver + env pass-through
* feat(testrun): launch iOS app via XCTest with env vars instead of simctl
* fix(ios): replace LaunchApp with BootedUDID; simctl launch moved to XCTest path
* test(cli): add tests for ios platform flag and ios-device flag parsing
* fix(sdk-ios): check semaphore wait result; resolve port from args and env; register extractors before start
* chore(docs): replace d2 diagram pipeline with mermaid
Remove docs/_diagrams/ and d2 build step from Makefile. The HTML
template already initialises mermaid.js; diagrams are now inline
code fences rendered client-side.
* docs(architecture): add mermaid diagram + web/CDP platform docs
Replace SVG img tag with inline mermaid flowchart showing both native
(Maestro sidecar + in-app SDK) and web (Chrome CDP) paths. Update
Processes, Transports table, and per-step cycle sections.
* docs(design-principles): update principles 1-4 for web platform
Principles 1, 2, 3, and 4 referenced Maestro and native-only concepts.
Add web/CDP context and update driver-is-an-interface to name both
sidecar and chrome implementations.
* docs(manual): add web prerequisites and folio-web example
Update --platform flag to list android, ios, web. Add web prerequisites
section (Chrome, no SDK needed) and folio-web quick-start to
getting-started.
* chore(gitignore): untrack inspect dist/index.html build artifact
index.html is regenerated by vite on every build with a new content hash,
making it permanently dirty. Only .gitkeep is needed for //go:embed to
compile on a fresh checkout. Also remove duplicate dist/* line and stale
d2 diagram ignore entries.
* feat(docs): click-to-zoom for mermaid diagrams
* docs(architecture): change diagram layout from LR to TB
* docs(getting-started): link npm and Maven Central package headers
* update docs root
* docs(spec): rewrite npm package README
Update usage example to current API, drop stale version-compatibility
and license sections.
* build(docs): output pages as pagename/index.html for clean URLs
Split DOCS_OUT into INDEX_OUT (index.md files stay as index.html) and
PAGE_OUT (all other pages become pagename/index.html). The __ROOT__
depth computation already handles the extra directory level correctly.
* chore(docs): update sidebar links to directory-style URLs
* docs: update cross-links from .html to directory-style paths
* ci(docs): remove d2 install step
* feat(docs): dark/light mode toggle
Add theme toggle button (top-right, fixed). Persists preference in
localStorage; falls back to prefers-color-scheme. Flash-free via inline
script in <head> that sets data-theme before first paint.
* fix(docs): fix inspect image path broken by directory URL restructure
* feat(docs): click-to-fullscreen for all article images
* fix(inspect): allow AssetsFS override in ServerOptions; drop unused request param from serveIndex
* fix(inspect): use in-memory FS in tests so TestAssets_FallbackToIndexHTML passes without web build
* fix(runner): allow nil connection for web platform
* fix(testrun): skip SDK handshake for web platform
* feat(folio-web): add React/Vite web sample app
* feat(folio-web): add sanderling spec

- Extract readLogcat() and readProcMetrics() as internal package-level
helpers parameterised by serial
- Add MaestroDriverBackend wiring maestro-client AndroidDriver
- Drop launcherActivity from DriverBackend interface and StubDriverBackend
- Add maestro-utils and micrometer-core as explicit compile deps
