We split this skill into the rules it gives an agent

2 rules. About 0 are common, 1 is distinctive, and 1 is very specific to this project.

  • ≈0

    Many files like this have a rule of this kind.

  • ≈1

    Distinctive · estimate

    This author's own choices. Worth a look.

  • 1

    Very specific

    Tied to their project's names, files or tools. Probably skip.

  1. Distinctive:

  2. Very specific:

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Run E2E Tests (local build)

You are building PocketPal AI from source in a worktree and running E2E specs against the local build. If the user wants to verify a PR matches the bit-identical artifact CI produced — without a local build — use /run-pr-e2e instead; that skill covers the CI-artifact path and defers to this one for everything generic.

Project facts (not exposed by --help)

  1. No CI gate on E2E. .github/workflows/e2e-tests.yml is a manual workflow_dispatch that only uploads the Android APK as an artifact; no specs are executed. Treat "E2E green" claims outside this skill as unverified until reproduced locally.
  2. Android uses a separate e2e flavor, package com.pocketpalai.e2e, output at android/app/build/outputs/apk/e2e/releaseE2e/app-e2e-releaseE2e.apk. The prod APK (outputs/apk/release/app-release.apk) is non-debuggable and has the src/__automation__/ bridge DCE-stripped — specs against it silently no-op. Always build via yarn android:build:e2e, never assembleRelease.
  3. iOS has no separate flavor. Same bundleId as prod (ai.pocketpal), differentiated only by the __E2E__ define from babel.config.js: transform-define driven by E2E_BUILD=true. yarn ios:build:e2e is the only correct build command for sim tests; yarn ios:build:ipa for iOS devices.
  4. Reset behaviour differs across platforms. iOS uses noReset:false, fullReset:false — install state (including downloaded models) is preserved across runs. Android uses fullReset:true — the app is reinstalled every run and any downloaded model is lost. Plan timing accordingly.
  5. e2e/devices.json is gitignored and per-worktree, copied from the submodule's local copy by tools/sync-worktree-config.sh; that copy may point Android appPath at the prod-release path. Each Android appPath must match the APK under test: the e2e-flavor output (../android/app/build/outputs/apk/e2e/releaseE2e/app-e2e-releaseE2e.apk) for a local yarn android:build:e2e. tools/run-pr-e2e.sh rewrites it to the APK it fetched. A wrong path surfaces as WebDriverError: The application at '...' does not exist, even when the build itself succeeded.
  6. TIMEOUTS.appReady = 60s in e2e/fixtures/models.ts. Most specs block on the chat-input testID for 60s before doing anything else. A broken first-paint manifests as no such element 'chat-input' after roughly the appReady timeout.

Available specs

Pick the smallest spec that exercises what changed; default quick-smoke. Core specs live in e2e/specs/*.spec.ts (quick-smoke, load-stress, benchmark-matrix, memory-profile, visual-capture, diagnostic), feature specs in e2e/specs/features/*.spec.ts (thinking, language, draft-autosave, remote-server, talent-tool-use). Read references/specs.md for what each tests and when to use it. benchmark-matrix, memory-profile, tts-memory-profile, visual-capture, and diagnostic are measurement infrastructure, excluded from the /run-pr-e2e default list.

Parse input

Extract from $ARGUMENTS:

  • Worktree (optional): if a branch name is given, check it out in a dedicated ./worktrees/E2E-<safe-name> via ./tools/create-worktree.sh ... --detach --ref origin/<branch>. If main, use ./worktrees/E2E-main. If omitted, use the current task worktree if there is one; otherwise stop and ask the user which worktree. (For the PR-CI-artifact path, redirect to /run-pr-e2e.)
  • Platform: ios, android, both (default: both).
  • Devices: all / virtual-only / real-only / connected / comma-separated IDs (runner default: all).
  • Spec: any basename from the catalogs above (the runner resolves both specs/ and specs/features/); default quick-smoke.
  • Flags: pass through --each-model, --each-device, --all-models, --skip-build, --dry-run, --models a,b. Anything else: consult npx ts-node scripts/run-e2e.ts --help.

Step 1 — Pre-flight

Verify before starting a run:

  • Worktree: reuse an existing one for the branch when present; otherwise create with ./tools/create-worktree.sh (--detach --ref origin/<branch>, or --ref origin/main for main). Never test inside repos/pocketpal-ai/ — it's a read-only submodule.
  • Local branch is in sync with origin. Stale checkouts produce results that don't reflect the code being shipped.
  • iOS simulator is booted (the runner does not boot it).
  • Android emulator or device is attached and showing as device in adb devices.
  • Phone claimed. Claim a phone through agistry before driving it and release it after (a pipeline stage uses the DEVICE its orchestrator claimed); iOS runs go through ios-router (this host has no iOS toolchain).
  • Appium ports 4723 and 4724 are free — the WDIO config spawns Appium on these (see wdio.{ios,android}.local.conf.ts); a leftover daemon from a previous run causes session creation to hang.

Step 2 — One-time worktree setup

Each fresh worktree needs three project-specific things beyond root yarn install:

  • e2e/ has its own package.json (WDIO + Appium client deps). Run yarn install separately in that subdirectory.
  • ios/ has a Gemfile that pins xcpretty and the cocoapods version. Install via Bundler before pod install, otherwise yarn ios:build:e2e fails opaquely — xcpretty swallows the real xcodebuild error.
  • pod install after any Podfile.lock change (llama.rn upgrades, new native deps).

Then verify e2e/devices.json (gitignored, per-worktree, synced on creation). For a local yarn android:build:e2e, each Android appPath must be ../android/app/build/outputs/apk/e2e/releaseE2e/app-e2e-releaseE2e.apk; the synced copy often holds the prod-release path, which fails Android session creation with APK does not exist.

Step 3 — Run the pipeline

Entry point: npx ts-node scripts/run-e2e.ts from inside e2e/. Required flags: --platform <ios|android|both> and --spec <name>. Everything else is documented in --help.

Non-obvious flag semantics:

  • --dry-run first whenever changing platform/devices/spec — it prints the matched targets and per-device WDIO invocations without spending the build budget.
  • --each-device is required to iterate over more than one device from devices.json. Passing --devices a,b alone does not imply --each-device; without it the runner picks the default device only.
  • Builds are sequential (iOS first, then Android). Cold builds typically run ~10-15 min iOS + ~3-5 min Android per worktree.

Step 4 — Report

Reports land in e2e/reports/<timestamp>/:

  • summary.json — overall pass/fail + per-device breakdown.
  • junit-results.xml — merged JUnit across devices.
  • <device-id>/[<model-id>/] subdirectories — per-run JUnit + screenshots/failure-*.png.

For each failure, open the per-device subdirectory and look at the failure screenshot and the per-device JUnit before drilling into the spec.

Failure-mode lookup

SymptomLikely cause
WebDriverError: The application at '...app-release.apk' does not existe2e/devices.json Android appPath does not match the APK that was built or fetched. Fix the path; the build itself is fine.
iOS red box No script URL provided. unsanitizedScriptURLString = (null)The installed app on the sim is a Debug build expecting Metro, not the Release .app from the build. Uninstall and reinstall from the new .app.
no such element 'chat-input' ~appReady seconds after session start (iOS)First-paint is broken, or the install on the sim is from a different build than the .app on disk. Confirm install matches build before deeper investigation.
iOS BUILD FAILED with no error text above itBundler gems (specifically xcpretty) are missing in ios/. Install Bundler gems, then retry.
iOS build succeeds but the .app won't launch after a Podfile.lock changePods are stale. Re-run pod install.
Android Appium connects but session creation hangs >60sA stale Appium daemon is holding port 4723/4724. Free the ports and retry.
Run times shorter than the spec's workload would implyiOS preserves install state, so a previously downloaded model short-circuits the download step. Compare timings only with a clean install.

Notes

  • The runner script is scripts/run-e2e.ts. There is no run-e2e-pipeline.ts.
  • devices.json and real-iOS builds (yarn ios:build:ipa, not :e2e): see Project facts 3 and 5.
