lev-os Apple Tester Skill
Purpose
apple-tester is a tester harness, not an autonomous runtime. Default usage is direct command execution + dev watch loop. Use server mode only when you need persistent session state or streamed logs.
Use apple-tester as the only public entrypoint. Do not invoke apple-driver (or agent-apple) directly for daemon/session workflows.
Strict loop
Always run this loop:
snapshot- Plan one action
- Execute one action
- Verify with
is/get/assert - Repeat
Never run free-form multi-action plans without verification.
Quick start
If apple-tester is not on your PATH yet, install it once from the repo root:
pnpm apple-tester:cli:install
apple-tester doctor --build-driver
apple-tester server start
apple-tester session start --macos
apple-tester snapshot --json
apple-tester tap @m1
apple-tester is visible @m1
apple-tester session stop
apple-tester server stop
Host input safety
macOS host-input gestures are blocked by default to avoid stealing local mouse/keyboard focus.
Use --allow-host-input only for explicit gesture actions:
apple-tester session start --macos --allow-host-input
apple-tester hold @m1 --duration-ms 900 --allow-host-input
apple-tester right-click @m3 --allow-host-input
iOS flow
apple-tester server start
apple-tester session start --ios --udid <SIM_UDID>
apple-tester snapshot --json
apple-tester tap @i1
apple-tester swipe --from 200,700 --to 200,250
apple-tester session stop
apple-tester server stop
macOS gestures
apple-tester hold @m1 --duration-ms 900 --allow-host-input
apple-tester longpress --coords 640,380 --allow-host-input
apple-tester right-click @m3 --allow-host-input
apple-tester swipe --from 400,500 --to 900,500 --duration-ms 500 --allow-host-input
Promotion
Promotion compiles a successful exploratory run into deterministic XCTest files and a promotion manifest:
apple-tester promote --run-id <RUN_ID> --platform ios --name "Login Smoke"
apple-tester promote --run-id <RUN_ID> --platform ios --name "Login Smoke" --dry-run --diff-lines 120
apple-tester promote --run-id <RUN_ID> --platform ios --name "Login Smoke" --dry-run --write-report ./artifacts/promotion-report.json
Output targets:
- iOS:
apps/ios/UITests/Generated/*.swift - macOS:
apps/macos/UITests/Generated/*.swift
Log streaming for agents
For parser-friendly polling, prefer NDJSON log output:
apple-tester logs --json --follow | jq -c '.entries[] | {seq, level, message}'
Canonical local development loop
pnpm dev:watch
This performs deterministic change detection and targeted rebuilds without relaunching apps by default (--no-relaunch).
Notes
right-clickis macOS-only.hold/longpressuse press-and-hold semantics on macOS and best-effort equivalent on iOS.- Prefer accessibility identifiers in app code for stable promoted tests.
- Use
apple-tester logs --followfor live daemon diagnostics when actions fail.
Technique Map
- Identify scope — Determine what the skill applies to before executing.
- Follow workflow — Use documented steps; avoid ad-hoc shortcuts.
- Verify outputs — Check results match expected contract.
- Handle errors — Graceful degradation when dependencies missing.
- Reference docs — Load references/ when detail needed.
- Preserve state — Don't overwrite user config or artifacts.
Technique Notes
Skill-specific technique rationale. Apply patterns from the skill body. Progressive disclosure: metadata first, body on trigger, references on demand.
Prompt Architect Overlay
Role Definition: Specialist for apple-tester domain. Executes workflows, produces artifacts, routes to related skills when needed.
Input Contract: Context, optional config, artifacts from prior steps. Depends on skill.
Output Contract: Artifacts, status, next-step recommendations. Format per skill.
Edge Cases & Fallbacks: Missing context—ask or infer from workspace. Dependency missing—degrade gracefully; note in output. Ambiguous request—clarify before proceeding.
