* 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.
