* 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
* 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
* fix(chrome): use InsertText for multi-char text input
* feat(hierarchy): add Screen field populated from sanderling-screen attr
* fix(chrome): auto-detect viewport from CSS vars, fix InputText accumulation, expose route as screen
* fix(runner): fall back to hierarchy root screen when snapshot screen is empty
* fix(folio-web): broaden loggedIn extractor to all authenticated pages
* test(folio): replace tautological properties with 4 domain invariants
Drop properties that can't fail (e.g. List.size >= 0, balances are Long
integers) or that just check the extractor itself (account_count equals
accounts.length). Keep auth routing liveness, error-clear liveness, and
reachability goals.
Add four properties that target the real code paths:
- balanceMatchesTransactionDelta: a new ledger row shifts the balance
by exactly its signed amount (credit +, debit -).
- totalEqualsSumOfAccounts: home total equals sum of per-account
balances at every state, not only on home.
- balanceChangeRequiresActiveAccount: an account's balance can only
change while that account is the active one in the navigator.
- duplicateAccountNamesRejected: account names are unique under the
app's actual dedup rule (case-insensitive after trim).
* chore(folio): upgrade sdk-android to io.github.priyanshujain.sanderling:0.0.1-rc4
Group id moved from io.github.priyanshujain to
io.github.priyanshujain.sanderling in the rc4 publish.
* chore(folio): pin @sanderling/spec to 0.0.1-rc4
* refactor(sdk-android): publish under io.github.priyanshujain.sanderling
Move the published Maven coordinates to a sanderling sub-namespace so the
brand is visible in the dependency line (was io.github.priyanshujain:sdk-android).
Sub-namespace is auto-allowed by Sonatype under the verified parent groupId.
* chore: update sdk-android coordinates in folio + docs
Follow the groupId change to io.github.priyanshujain.sanderling:sdk-android.
* ci(docs): use --version flag for d2 install script
The d2 installer accepts --version vX.Y.Z, not --tag. The --tag form
was rejected as "unrecognized flag" on the docs workflow run after
PR #26 merged.
* refactor: rename examples/sample-app to examples/folio
Directory-level rename and path references in Go tests, bundle-check,
top-level README, and getting-started docs. Package declarations,
Gradle config, iOS bundle IDs, and class names follow in later commits.
* refactor(folio): rename Kotlin package dev.uatu.sample to app.folio
Moves source dirs and sqldelight schema from dev/uatu/sample to
app/folio, updates package declarations and imports, and switches
Android namespace/applicationId, iOS binaryOption bundleId, and
sqldelight database packageName to the new identifier.
* refactor(folio): rename SampleApplication to FolioApplication
Android manifest now points at .FolioApplication with label 'Folio'
instead of 'Uatu Sample'.
* refactor(folio): set iOS bundle id and display name to Folio
bundleIdPrefix + PRODUCT_BUNDLE_IDENTIFIER -> app.folio.
CFBundleName + CFBundleDisplayName -> 'Folio'.
* refactor(folio): update demo email to [email protected]
* refactor(folio): point justfile at app.folio bundle id
Updates xcrun simctl launch target, uatu test --bundle-id, and the
build/uninstall comments to reference folio instead of sample.
* test: update fixture package ids to app.folio
Sidecar activity-resolver test and verifier spec-integration XML
fixtures referenced the old dev.uatu.sample Android package. Updates
them to match the folio app's real package id so the tests stay
representative of what the CLI sees on-device.
* test(verifier): rename SampleApp identifiers to Folio
Renames TestSampleAppSpec* functions, bundleSampleAppSpec helper, and
sampleAppHierarchyXML const (now loginHierarchyXML for consistency with
the other per-screen fixtures). Updates trailing sample-app mentions in
comments and assertion messages.
* refactor(folio): rename Gradle/npm/wasm project identifiers to folio
settings.gradle.kts rootProject.name, package.json + package-lock.json
name, and the WasmJS index.html <title> all still read 'uatu-sample' /
'Uatu Sample'. Realigns them with the Folio brand.
* docs(folio): rewrite README title + getting-started bundle id
examples/folio/README.md is now titled 'Folio' with the Kotlin source
paths corrected to app/folio. Getting-started example uses --bundle-id
app.folio. Harness launch message is now generic ('app under test')
since uatu-sample-harness is not specific to folio.
* chore(folio): drop trailing 'sample' reference in gradle.properties
* refactor(folio): rename LoginPage composable to LoginScreen
Align with KMP/Android industry convention (NowInAndroid, Cash App,
JetBrains samples use Screen, not Page).
* refactor(folio): rename HomePage composable to HomeScreen
* refactor(folio): rename AddAccountPage composable to AddAccountScreen
* refactor(folio): rename LedgerPage composable to LedgerScreen
* refactor(folio): rename AddTransactionPage composable to AddTransactionScreen
* refactor(folio): split Models.kt into app.folio.data package
Account, Transaction (with TxnType), and Session move into their own
files under app.folio.data, matching NowInAndroid-style per-type
organization.
* refactor(folio): move data layer into app.folio.data package
Repository, LedgerStore (expect + interface), SqlLedgerStore,
WebLedgerStore, DriverFactory (expect + actuals), AndroidLedgerContext,
and Snapshot move into app.folio.data. Update all consumer imports.
* refactor(folio): move Navigation into app.folio.navigation package
Split the former Navigation.kt into Route.kt (sealed interface) and
Navigator.kt (singleton). Update consumer imports across screens,
App.kt, and FolioApplication.
* refactor(folio): move Platform and Format into app.folio.platform
Both files carry expect declarations (Platform object, formatDate);
grouping them into a dedicated platform package makes the KMP seam
obvious and mirrors the structure used by JetBrains samples.
* refactor(folio): move login into feature/auth package
Create app.folio.feature.auth with LoginScreen + LoginUiState. Inline
the former Auth.kt (DEMO_EMAIL, DEMO_PASSWORD, checkCredentials) into
LoginScreen since it is the sole caller.
* refactor(folio): move HomeScreen into feature/home package
* refactor(folio): move account creation into feature/account package
AddAccountScreen gets its own AddAccountUiState colocated with the
screen, replacing the shared UiState.addAccountError.
* refactor(folio): move ledger screens into feature/ledger package
LedgerScreen and AddTransactionScreen move into app.folio.feature.ledger
with AddTransactionUiState (txnError, txnFormType) colocated. The
former catch-all UiState.kt is removed now that each screen owns its
state alongside its UI.
* refactor(folio): split Theme.kt; move theme and icons to subpackages
Theme split into Theme.kt (tokens, layout dims, LedgerTheme) and
Type.kt (typography) under app.folio.ui.theme. Icons moves to
app.folio.ui.icon. Update every consumer's imports to match.
* refactor(folio): split ui components into per-file under ui/component
Former Widgets.kt and Components.kt become 10 focused files: AppButton,
Card, EmptyState, ErrorText, FieldLabel, Header, IconButton (w/
BackButton), Screen, Segmented, TextInput. Matches NowInAndroid style
of one composable per file in a designsystem/component package.
* chore(folio): consolidate uatu testing files under uatu/ folder
Move spec.ts, package.json, package-lock.json into examples/folio/uatu
so all uatu-specific testing artifacts live in one place. runs/ and
node_modules/ follow the same convention (both remain gitignored).
Update justfile, README, and the two Go consumers (bundle-check tool +
verifier/trace tests) that referenced the old path.
* refactor(trace): drop folio path in writer test
Round-trip only needs a non-empty string; neutralize to keep the
library free of folio references.
* refactor(sidecar): neutralize ResolveActivity test fixtures
Swap app.folio for com.example.app in the fixture strings so the
sidecar tests don't reference the example app by name.
* refactor(bundle-check): take spec path as argument
Previously the tool hardcoded examples/folio/uatu/spec.ts. Accept a
positional spec path instead so the tool works for any example and
leaves no folio reference in the library surface.
* test(verifier): add neutral integration spec and hierarchy fixtures
Adds testdata/integration_spec.ts with two routes ("list", "form"),
an InputText on text_field, a Tap on primary/secondary_action, a
safety property (itemCountNonNegative), and a liveness property
(submitEventually). Adds hierarchies_test.go with matching XML
fixtures. Constants intentionally go in a _test.go at package root
rather than testdata/hierarchies.go because go skips .go files
under testdata/.
* refactor(verifier): replace folio integration tests with neutral ones
Renames bundleFolioSpec -> bundleIntegrationSpec and the three Test*
entry points to TestIntegrationSpec*. Uses the synthetic spec and
hierarchies added in the previous commit so the library's test suite
no longer references examples/folio at all.
Folio-specific coverage remains covered by examples/folio/justfile's
'just test' which exercises the real spec on device/emulator.
* chore: remove cmd/uatu-sample-harness
Not referenced by Makefile, docs, CI, or any script. Duplicates the
adb reverse helpers already in cmd/uatu/test_run.go, and its name
implies ownership by the sample app which violates the library/
example decoupling. If a bare-protocol debugging tool is later
needed it belongs inside cmd/uatu/.
* docs(folio): drop Layout section and KMP layout paragraph; fix AVD override syntax
The directory-tree Layout section rots faster than the code and
duplicates what ls shows for free. The expect/actual paragraph in
Stack was the same kind of filler. The README also claimed 'just
AVD=Pixel_7 test' but the justfile reads AVD as an env var via
env_var_or_default, so the correct invocation is 'AVD=Pixel_7
just test'.
* feat(ltl): add Now/Next/Eventually/Implies/Or/And/Not formulas
Replace the fold-with-latch evaluator with a residual-formula reducer.
Each Observe() instantiates a fresh obligation from the root (stripping
an outer Always), reduces each pending obligation against current state,
latches Violated on first failure, and surfaces Pending verdicts for
deferred obligations. Existing Always/Pure/Thunk tests continue to pass.
* feat(ltl): support relative duration for eventually().within()
* feat(proto): add Swipe, PressKey, RecentLogs RPCs
* feat(verifier,runner): formula handles, new action kinds, rich state
- verifier: add formula-spec registry; bindNow/bindNext/bindEventually with
chainable .implies/.or/.and/.not and .within(n,unit) on eventually; bindFrom
for uniform sampling. bindAlways keeps accepting plain predicates.
- verifier: store lastTree, lastAction, step time, logs, exceptions on the
Verifier; SnapshotInput replaces the (snapshots, tree) pair. stateObject now
produces state.lastAction/time/logs/exceptions matching the TS State type.
- verifier: make taps/swipes/waitOnce/pressKey built-in generators actually
fire; taps picks a clickable, enabled element from the last hierarchy.
- agent: add exceptions field to Message wire format.
- driver: add Swipe/PressKey/RecentLogs to Driver interface; wire maestro
client and mock driver. LogEntry exposed for runner consumption.
- runner: apply Swipe/PressKey/Wait actions; collect logcat and exceptions;
pass lastAction and step time into PushSnapshot.
* feat(spec-api): LTL operators, new actions, richer State
- ltl.ts exports now/next/eventually; always overload accepts a Formula
- types.ts: Formula gains implies/or/and/not; EventuallyFormula adds .within;
State gains lastAction/time/logs/exceptions; Swipe/PressKey/Wait action types
- actions.ts: Swipe/PressKey/Wait/from constructors; waitOnce + pressKey
default generators
- tests exercise the chaining, sampling, and new actions through a recorded
fake runtime
* feat(sidecar): add swipe, pressKey, recentLogs RPC handlers
* feat(sdk-android): capture uncaught exceptions
Install a default uncaught handler on Uatu.start, chained with any
existing handler so Android's crash reporter still runs. Expose
Uatu.reportError for callers to forward caught throwables. A bounded
circular buffer (default 50) drains into each STATE message's new
exceptions field. Protocol.kt serializes/deserializes the field,
matching the Go wire format added to internal/agent/protocol.go.
* feat(spec-api): add @uatu/spec/defaults/properties bundle
* feat(sample-app): exercise new LTL operators + defaults
spec.ts now imports eventually/next/now/from from @uatu/spec and
noUncaughtExceptions from @uatu/spec/defaults/properties. It declares
three properties that exercise the new surface:
- accountCountNonNegative: plain always() safety
- addAccountAdvances: always(now(x).implies(next(y)))
- eventuallyLoggedIn: eventually(p).within(30, "seconds")
- noUncaughtExceptions: imported default
The weighted actions root uses from() for random phone/name sampling
and entries for taps/swipes/waitOnce/pressKey built-ins.
SampleApplication gains a debug hook gated on the system property
uatu.inject_error so the e2e run can synthesize an Uatu.reportError and
verify noUncaughtExceptions violates.
cmd/uatu/test_run.go adds a subpath alias so specs importing
"@uatu/spec/defaults/properties" resolve against the in-tree source
when running from the uatu checkout. The spec-integration tests swap
the old click-counter fixtures for the new login hierarchy.
* feat(trace): record swipe/key/wait details + exceptions
trace.Step gains an Exceptions array so the trace captures the
class/message/stackTrace for each SDK-reported throwable in a step.
trace.Action gains FromX/FromY/ToX/ToY/Key/DurationMillis so the full
payload of Swipe/PressKey/Wait actions is visible in trace.jsonl.
sample-app's debug error hook now gates on ApplicationInfo.DEBUGGABLE
instead of a system property (adb setprop fails on non-rooted
emulators).
* chore(sample-app): hoist gradle wrapper to sample-app root
* chore(sample-app): add KMP root gradle config
* chore(sample-app): add composeApp KMP module build config
* chore(sample-app): add Android manifest for composeApp
* feat(sample-app): add shared domain models and auth constants
* feat(sample-app): add shared number and date formatting
* feat(sample-app): add cross-platform storage, clock, and id
* feat(sample-app): add shared repository with file-backed state
* feat(sample-app): add shared in-memory navigator
* feat(sample-app): add Compose theme and design tokens
* feat(sample-app): add shared UI components (icons, screen, widgets)
* feat(sample-app): add Login and Home pages
* feat(sample-app): add AddAccount, Ledger, AddTransaction pages
* feat(sample-app): add App root composable with routing
* feat(sample-app): add Android Application and Activity hosting Compose UI
* chore(sample-app): remove legacy android module (replaced by composeApp)
* chore(sample-app): bump to latest stable Kotlin/AGP/Compose deps
* fix(sample-app): make iOS compile (drop @Volatile, set bundleId)
* feat(sample-app): add xcodegen spec, SwiftUI host, and iOS Info.plist
* chore(sample-app): ignore build artifacts and generated xcodeproj
* chore(sample-app): update justfile for composeApp layout, add ios target
* docs(sample-app): rewrite README for KMP + iOS flow
* refactor(sample-app): drop in-app status bar and formatClock
* feat(sample-app): add SQLDelight schema and per-platform drivers
* refactor(sample-app): back Repository with SQLite, drop file serializer
* feat(sample-app): wire native back on Android and iOS edge swipe
* feat(sample-app): semantic roles, labels, and a11y descriptions
* fix(sample-app): link libsqlite3 for iOS target
SQLDelight's native driver needs libsqlite3.tbd on iOS; without it the
linker fails with undefined _sqlite3_bind_blob and friends.
* refactor(sample-app): abstract storage behind LedgerStore interface
Platform-specific createLedgerStore() returns a SqlLedgerStore backed
by SQLDelight on Android + iOS. Opens the door for a pure in-memory
web implementation that does not require a SQLite driver.
* feat(sample-app): add wasmJs target with in-memory LedgerStore
Wires a Compose Multiplatform browser canvas entry point. The web
implementation of LedgerStore is an in-memory model with localStorage
persistence, so it does not need a SQLite driver. Back navigation maps
the browser back button to the same BackHandler contract Android and
iOS use.
* chore(sample-app): settings + gitignore for wasmJs dev run
Registers the Node.js distributions repository and switches
repositoriesMode to PREFER_PROJECT so the Kotlin wasmJs plugin can
download its toolchain. Adds kotlin-js-store (lockfile) and ignores
runs/, web screenshots, playwright-mcp scratch output.
* fix(sample-app): singularize transaction count on Home
Shows "1 transaction" not "1 transactions" for accounts with a single
transaction; falls back to "$count transactions" otherwise.
* fix(runner): surface non-deadline WaitForIdle errors
Previously the WaitForIdle return value was discarded entirely, hiding
real driver failures (gRPC transport errors, sidecar crashes) behind
the expected deadline-exceeded case. Log non-deadline errors so they
are visible without changing control flow.
* chore(sample-app): drop unused uptime_millis extractor
Registered in SampleApplication but never consumed by spec.ts.
* fix(sample-app): drop trivial appIsRunning property
app_state was hardcoded to 'running' so the property was a tautology
that could never fail. Removing both the extractor and the property
is the simplest fix; demo-grade properties that can fail land next.
* feat(sample-app): add Reset button that zeroes clickCount
Pairs with the next commit's tap-reset action so the fuzzer can
violate clickCountNeverDecreases and demonstrate uatu actually
finding a property violation.
* feat(sample-app): add tap-reset action to exercise Reset button
Weighted at 10/122, fuzzer reaches it within a short run. Pairs with
the Reset button to demonstrate uatu detecting the
clickCountNeverDecreases violation.
* fix(runner): filter WaitForIdle errors via context state, not errors.Is
errors.Is(err, context.DeadlineExceeded) misses gRPC's wrapped
status.DeadlineExceeded, so every step under the maestro driver
logged a spurious warning. Check idleCtx.Err() instead — captures
both deadline-fired and parent-canceled cases regardless of how the
driver wraps them.
* chore(sample-app): tune action weights so demo violates in ~30s
Prior weights left tap-reset rare enough that short demo runs missed
the violation by chance. Bumped to 30/107, with typeUsername reduced
since username noise doesn't help exercise clickCount.
* refactor(runner): route warnings through slog
Adds Options.Logger (defaults to slog.Default()) and converts the
three warning sites that were using fmt.Printf. Progress line stays
on Printf since it's user-facing UI, not a log. Makes the warnings
testable via a capturing handler.
* test(runner): assert WaitForIdle driver errors are logged
Captures slog output via TextHandler into a buffer and asserts the
warning message + injected error text appear when the mock driver
returns a non-context error from WaitForIdle. Guards against a
regression of the silent-error swallow.
* fix(sdk-android): add @JvmOverloads to Uatu.start
Java callers can now invoke start(application) without supplying a
Configuration, matching the Kotlin default-arg ergonomics.
* feat(agent): add protocol_version to HELLO handshake
ProtocolVersion=1 lives on Message and is set by Hello(). Server.Accept
rejects mismatches with a clear error. SDK upgrades that don't change
the wire format keep the same protocol_version; bump on breaking changes.
* test(agent): assert protocol_version in Hello round-trip
* feat(sdk-android): send protocol_version=1 in HELLO
Mirrors agent.ProtocolVersion on the Go side. Bump in lockstep with
the Go constant when the wire format breaks.
* chore(sample-app): pull @uatu/spec from npm next tag
Replaces the file: dep. Copy-paste users can now npm install against
the registry. The release workflow publishes pre-release tags to
npm dist-tag 'next', so the sample tracks the latest rc without
manual version bumps. Lockfile currently resolves to 0.0.1-rc3.
* fix(runner): warn on malformed screen snapshot
screenFromSnapshot swallowed json.Unmarshal errors, so a non-string
screen value silently became "" in the step log and trace while the
verifier still saw the raw JSON. Return the error and warn at the
call site, matching the hierarchy warning pattern.
* docs: clarify --avd is optional for uatu test
The CLI accepts --avd as an empty-string default (cmd/uatu/main.go:49)
and only requires it when no device is connected and multiple AVDs
exist (cmd/uatu/android_env.go:63). Docs and examples that showed it
as required or always-passed were misleading.
* fix(runner): surface focus-tap errors in InputText action
A failed Tap/TapSelector before InputText was swallowed, so text typed
into the wrong field (or no field) still reported success. Return the
error so the step fails explicitly.
* feat(sample-app): add username EditText and snapshot
Gives the spec a real EditText target (content-desc: username_field)
so the InputText action path can be exercised end-to-end. The typed
value is mirrored into MainActivity.username and surfaced as the
"username" snapshot for spec assertions.
* feat(sample-app): exercise InputText action against username field
Adds typeUsername action and usernameNeverShrinks property to the
sample spec, and extends the integration test to assert the bundled
spec emits an InputText(desc:username_field, "alice") action and that
the property correctly violates when a snapshot reports a shorter
string.
* fix(cli): fall back to node_modules for @uatu/spec resolution
Drop the hard failure when the uatu source tree is not reachable from
the spec file. Users integrating uatu in their own app have @uatu/spec
installed via npm; esbuild now resolves it from node_modules.
* build(gradle): drop :sample-app include from root settings
The sample now has its own Gradle project in examples/sample-app/android.
* build(sample-app): vendor gradle wrapper
Users running the sample build the APK via ./gradlew from inside the
sample-app's own android/ directory, no repo-root wrapper required.
* build(sample-app): make gradle project standalone
Drop the project(':sdk-android') dependency in favor of the Maven
Central coordinate io.github.priyanshujain:sdk-android. The sample now
owns its settings.gradle.kts and gradle.properties, so it builds
without any pieces of the uatu source tree.
* chore(sample-app): declare @uatu/spec npm dependency
Mirrors what a downstream user would put in their own package.json.
Uses file: for pre-release development; becomes a normal semver pin
once @uatu/spec ships to npm.
* docs(sample-app): rewrite justfile and add README
Justfile drops repo_root; all recipes run against the local gradle
wrapper and uatu from PATH. README is scoped to what a user needs to
run the sample against their own device.
* docs(manual): update sample install steps to standalone layout
./gradlew :sample-app:installDebug no longer exists; the sample owns
its own wrapper under android/.
* feat(sdk): log when Uatu.start succeeds
Silent SDK start makes the "SDK didn't connect" failure mode
impossible to debug. One INFO line at start time is enough.
* fix(sidecar): launch via am start -W instead of monkey
monkey -p <pkg> -c LAUNCHER 1 is unreliable on API 36+: it reports no
error but silently fails to start the activity, so the SDK never runs
and the CLI times out on the SDK-accept handshake.
Resolve the launcher activity via `cmd package resolve-activity
--brief` and launch it with `am start -W -n`. -W makes the call block
until the activity is up, which also makes the subsequent SDK
accept timing deterministic.
* feat(cli): auto-resolve Android device; boot AVD if none connected
--avd becomes optional. Resolution order:
- use any already-connected adb device;
- else if --avd names an existing AVD, boot it and wait for boot;
- else if --avd is missing or names no AVD, error with a clear message.
Falls back to $ANDROID_HOME/emulator/emulator when the binary is not on
PATH, so a standard Android SDK install works without extra shell setup.
* docs(sample-app): AVD is optional; document both paths
just test runs against any connected device. If none, pass AVD=<name>
to have uatu boot the emulator for you.
* feat(cli): auto-discover Android SDK; auto-pick the lone AVD
adb and emulator are looked up via PATH, then $ANDROID_HOME,
$ANDROID_SDK_ROOT, ~/Library/Android/sdk, ~/Android/Sdk, and the
Homebrew cask path. The discovered platform-tools directory is
prepended to the sidecar's PATH so its adb subprocess calls work too.
When --avd isn't passed and no device is connected, the CLI picks the
sole local AVD and boots it. Multiple AVDs → error listing them.
* build(make): add `make install` that go-installs uatu onto PATH
Puts `uatu` into $GOBIN (or $GOPATH/bin) so the sample and any local
dev flow can call it without PATH= prefixes.
* docs(sample-app): zero-config just test; dotenv-load for persistence
Drop the expectation that users prefix commands with PATH=, ANDROID_HOME=,
or AVD=. `just test` now works as-is; optional knobs can be pinned in a
.env file alongside the justfile.
* fix(sample-app): auto-detect ANDROID_HOME for Gradle tasks
The Go CLI finds the SDK itself, but AGP still needs ANDROID_HOME to
resolve `sdk.dir`. The justfile now resolves it from env or canonical
install paths before invoking ./gradlew, so `just install` works out
of the box on a standard Android SDK setup.
* gitignore runs directory for sample app
Targets: install/uninstall the APK, build the uatu CLI, run 'uatu test'
against a named AVD, run the Go verify tests, and clean. Keeps the
example self-contained so users can 'just test AVD=pixel_7' after cloning.
Introduce examples/sample-app/spec.ts — a minimal property-based spec that
taps the sample app's "Click me" button and asserts click_count is
monotonic. Bundle-check and the trace writer test now reference the new
path.
Property ledgerBalanceMatchesTxns asserts displayed balance equals
sum(Given) - sum(Received) on either ledger screen. Catches the
class of bug where the server-fed CustomerModel.balance diverges
from the local-DB-fed CoreDatabaseDao sums (stale cache, partial
sync, deleted-txn handling glitch, etc.).
Generators are gated by screen state and weighted to push the run
through login -> home -> ledger quickly:
enterPhone (100), enterOtp (100), openCustomerOrSupplier (80),
taps (10), swipes (2).
Phone/OTP read from process.env via esbuild defines so credentials
never land in source. cmd/internal-tools/bundle-check is a quick
sanity tool to confirm the spec bundles before running uatu test.
