* 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
@sanderling/spec
TypeScript spec API for sanderling, a property-based UI fuzzer for mobile and web apps.
Spec authors write properties (what the app must always or eventually do), extractors (structured state from the UI), and action generators (what sanderling is allowed to do). The sanderling CLI evaluates the spec in a loop against a running app.
Install
npm install --save-dev @sanderling/spec
Usage
import { extract, always, eventually, now, actions, weighted, taps, swipes, InputText, Tap } from "@sanderling/spec";
const loggedIn = extract((s) => !!s.ax.find("id:home-tab-bar"));
const balance = extract<number>((s) => (s.snapshots.balance as number) ?? 0);
export const properties = {
balanceNeverNegative: always(() => balance.current >= 0),
loginSucceeds: eventually(() => loggedIn.current).within(30, "seconds"),
};
const doLogin = actions(() => {
if (loggedIn.current) return [];
const email = state.ax.find("id:email-field");
const submit = state.ax.find("id:sign-in-button");
if (!email || !submit) return [];
return [InputText({ into: email, text: "[email protected]" }), Tap({ on: submit })];
});
export const actions = weighted(
[50, doLogin],
[10, taps],
[2, swipes],
);
Works identically across Android, iOS, and web targets.
