* 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): use account_card:id desc, expose balance via text semantics
* fix(folio): embed accountId in LedgerScreen desc, expose values via text semantics
* fix(spec): replace desc-parsing with text-based parseDollarCents extraction
* 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).
Installs globalThis.__uatu__ with extract, always, actions,
weighted, tap, inputText, and stub taps/swipes. Load runs the
bundled spec, then pulls properties + actions out of globalThis.
PushSnapshot rebuilds state.snapshots and refreshes every
extractor handle's current/previous in registration order so
chained extractors observe up-to-date values.
Properties are wired through internal/ltl as Always(Thunk(...)),
so verdicts latch to violated as soon as a predicate returns
false. NextAction resolves actions/weighted recursively with a
seedable rand source for reproducible runs.
