GUI automation notes (Android wallet)

Canonical notes for graphical Android wallet tests against GOA / stage.

Minimal variant (implemented first) — status 2026-07

This is the minimal vanilla path we actually shipped; full dual-platform GUI is planned via flags (below), not required to use these scripts today.

Piece	Status	Notes
F-Droid published APK install	done	`net.taler.wallet.fdroid` 1.6.1 / 854
Source build + same smoke	done	`:wallet:assembleFdroidDebug` → `net.taler.wallet.fdroid.debug`
Default source branch	done	`dev/hernani-inference/fix-bank-withdraw-auto-exchange` (minimal GOA exchange auto-add)
Deep-link entry (≡ QR)	done	`adb` `VIEW` withdraw then pay (`taler://withdraw/…` → `taler://pay…`)
Explorer API mint (chain)	done	`run-goa-gui-chain.sh` (GOA + stage)
UI taps via uiautomator	done	best-effort Confirm/ToS/Pay; ANR → prefer Wait
Screenshots / logcat artifacts	done	under `out*`, `out-gui-chain/` (gitignored)
Host CLI e2e settlement	separate	`taler-monitoring.sh e2e` / `ladder` (not Android UI)
Reliable unattended Confirm on 4 GiB Linux host	limited	System UI ANR; use phone or more RAM
iOS GUI	not in this tree	see taler-ios `dev/hernani-inference/gui-workflows`
macOS full dual AVD helpers	upstream	taler-android `gui-workflows` (Homebrew); ported ideas here for Linux

Ground rule: bring it to run; app diffs only if needed and minimal; prefer extending existing dev/hernani-inference/* branches over new trees.

Minimalvariante: was geht / was nicht

Einschränkungen der aktuell implementierten Minimalvariante (deep-link + uiautomator best-effort). Kein voller Dual-Platform-GUI-Stack, kein Ersatz für Host-CLI-Settlement.

Geht (grün)

Fähigkeit	Wie / Hinweis
APK installieren	F-Droid `net.taler.wallet.fdroid` oder Source `assembleFdroidDebug` (`.debug`)
GOA-Exchange ohne manuelles Add	Source-Build von `fix-bank-withdraw-auto-exchange` (Default in `run-android-build-and-smoke.sh`)
Abheben + Bezahlen	Beide Beine: erst Withdraw-URI + Taps, dann Pay-URI + Taps (`DO_WITHDRAW`/`DO_PAY`)
Light UI-Drive	Confirm / Accept / Pay-Taps über Label-Suche (`lib_ui.py`, gui-smoke, chain)
Multi-Runden-Taps	`run-android-gui-smoke.sh` / `run-goa-gui-chain.sh` (best-effort)
Explorer-Mint (Kette)	`run-goa-gui-chain.sh` + `EXP_PW_FILE` (GOA + stage)
Stack-Wahl	`STACK=goa` / `stage` (Bank/Merchant-URLs)
Artefakte	Screenshots, UI-XML, logcat unter `out*` / `out-gui-chain/` (gitignored)
Hybrid-Smoke	Install + Intent + leichte Taps: `run-android-pay-smoke.sh`
Settlement nachweisen	Host-seitig: `taler-monitoring.sh e2e` / `ladder` (nicht Android-UI)
Flags abschalten	`AUTO_ANDROID=0` skip; `AUTO_GUI=0` → nur deep-link/pay-smoke

Geht nicht oder nur eingeschränkt (rot / gelb)

Beschränkung	Folge / Workaround
Unattended Confirm → settled im Emulator (~4 GiB Host)	Häufig System UI ANR; Taps bleiben hängen. Prefer Wait auf ANR-Dialog, echtes Gerät, oder Host mit mehr RAM. Kein zuverlässiges grünes E2E nur über GUI auf dem schwachen Emulator.
Vollständige Wallet-Settlement-Assertion in der GUI	Minimalvariante prüft nicht „Balance final / transfer_done“ in der App-Oberfläche. Proof bleibt CLI/e2e.
Kamera / physischer QR-Scan	Absichtlich nicht automatisiert; deep-link ist der Shortcut. Landing-QR-Pfade sind HTTP-Thema, nicht Android-GUI.
Browser-Shop-Checkout-UI	Kein Chromium/WebView-Drive; Pay-URI kommt per Template-`POST` + Intent.
Volles ToS-Scroll / alle Dialoge	Best-effort Accept-Tap; lange ToS oder unerwartete Sheets können hängen bleiben.
Published F-Droid allein auf GOA	Kann Exchange-Add / Spinner-Probleme zeigen → fix-branch-APK bauen; bei Spinner-Hang optional `fix-withdraw-spinner-fallback`.
iOS-GUI	Nicht in diesem Tree; siehe taler-ios `gui-workflows`.
macOS dual AVD / Homebrew-Helpers	Upstream `gui-workflows`; hier nur Linux-taugliche Port-Ideen.
*`AUTO_` in jedem Script erzwungen**	Design + teilweise verdrahtet; Wrapper-Checkliste noch offen.
`run-until-done` / CLI-Wallet in GUI-Skripten	Gehört zu CLI-Automation, nicht GUI; siehe `CLI-AUTOMATION-NOTES.md`.
CI grün = „User hat bezahlt“	Smoke = Intent + best-effort UI. Wirtschaftlicher Erfolg = Host-e2e / ladder / Explorer.

Erwartetes Ergebnis pro Schicht

Schicht	Erfolgskriterium Minimalvariante
A Install	APK installed, App startet
B Deep-link	Intent delivered, Wallet öffnet Withdraw/Pay-Flow
C GUI taps	Dump+Tap ohne Crash; ANR ggf. mit Wait; kein Garant für „Paid“
D Evidence	Artefakte geschrieben
Settlement	Außerhalb GUI: Host e2e/ladder

Wann Minimalvariante reicht

Smoke nach APK-/Branch-Build (Intent kommt an, App crasht nicht).
Manuelle Nacharbeit am Gerät nach vorbereiteten URIs.
GOA/stage Erreichbarkeit von Landing/Template + Wallet-Einstieg.

Wann nicht reicht → nächster Schritt

Unattended grünes Pay-E2E auf dem Emulator → mehr RAM / physisches Gerät, ggf. fix-withdraw-spinner-fallback.
Beweis „Münzen da / Merchant paid“ → CLI e2e/ladder, nicht GUI-smoke.
iOS / Dual-Platform → andere Repos/Flags, nicht diese Skripte.

Platform capability flags (planned + defaults)

Automation can run on hosts that support Android only, GUI tooling only (conceptual), or both. Flags keep that explicit for CI and laptops.

Proposed env flags

Variable	Values	Meaning
`AUTO_ANDROID`	`0` / `1`	Run Android wallet automation (adb, APK, emulator/device)
`AUTO_GUI`	`0` / `1`	Drive graphical UI (uiautomator taps, multi-round). If `0`, deep-link/CLI-only install smoke.
`AUTO_PLATFORM`	`auto` / `linux` / `macos` / `ios`	Host family (optional override)
`EMULATOR_HEADLESS`	`1` (default) / `0`	No host window (`-no-window`). Server/CI-safe.
`WINDOWED`	`0` / `1`	Shortcut: `WINDOWED=1` ⇒ show emulator window (`EMULATOR_HEADLESS=0`)
`EMULATOR_GPU`	default `swiftshader_indirect`	Guest GLES still runs headless (layout/taps/screenshots). Override `host` only if windowed + real GPU.
`AUTO_START_EMULATOR`	`1` (default) / `0`	If no adb device, start AVD via `start-android-emulator.sh --wait`

Headless mode (default)

Default for all GUI / pay smokes: no window on the host. Opening an emulator GUI on servers (or headless CI) is wrong; these scripts therefore start the AVD with -no-window and still keep graphics logic in the guest:

Piece	Headless default
Host window	off (`-no-window`, `QT_QPA_PLATFORM=offscreen`, no `DISPLAY`)
Guest GLES	on via SwiftShader (`-gpu swiftshader_indirect`)
UI automation	on — `uiautomator` dump/tap + `screencap` (no X11 needed)
Audio / boot anim	off (`-no-audio -no-boot-anim`)

# explicit (same as default)
./start-android-emulator.sh --wait

# or let smoke auto-start headless AVD when no phone is plugged in
STACK=goa ./run-android-gui-smoke.sh

# laptop: show the emulator window
WINDOWED=1 ./start-android-emulator.sh --wait
# or: EMULATOR_HEADLESS=0 EMULATOR_GPU=host ./start-android-emulator.sh --wait

Shared code: lib_android_env.sh + start-android-emulator.sh.

Semantics:

`AUTO_ANDROID`	`AUTO_GUI`	Behaviour
`1`	`0`	Android install + deep-link smoke only (no multi-round taps)
`1`	`1`	Android + graphical drive (vanilla GUI / chain)
`0`	`1`	Reserved (e.g. future desktop/web GUI); currently no-op with a clear message
`0`	`0`	Skip mobile automation

Defaults by host (when flags unset)

Host (`uname -s`)	Default `AUTO_ANDROID`	Default `AUTO_GUI`	Rationale
Linux	`1`	`1` if device/emulator present, else scripts exit 3	This repo’s day-to-day path; Android only (no iOS here)
Darwin (macOS)	`1`	`1`	Can run Android emulators and (separately) taler-ios GUI helpers; both flags on for Android scripts; iOS is out of tree
Other	`0`	`0`	Fail closed

Linux default = Android (no second mobile platform in this suite).
macOS may enable both ecosystems in the wider monorepo sense; for these scripts only Android is implemented — set AUTO_ANDROID=1 (default) and keep iOS under taler-ios.

Resolution helper (convention for future wrappers)

# Example for a future run-all-mobile.sh
os=$(uname -s)
: "${AUTO_PLATFORM:=auto}"
case "$AUTO_PLATFORM" in
  auto) case "$os" in Linux) AUTO_PLATFORM=linux ;; Darwin) AUTO_PLATFORM=macos ;; *) AUTO_PLATFORM=other ;; esac ;;
esac
case "$AUTO_PLATFORM" in
  linux)
    : "${AUTO_ANDROID:=1}"
    : "${AUTO_GUI:=1}"
    # no iOS
    ;;
  macos)
    : "${AUTO_ANDROID:=1}"
    : "${AUTO_GUI:=1}"
    # optional later: AUTO_IOS=1 for taler-ios scripts
    ;;
  *)
    : "${AUTO_ANDROID:=0}"
    : "${AUTO_GUI:=0}"
    ;;
esac

Scripts today implement Android only; they should honour:

AUTO_ANDROID=0 → exit 0 with “skipped (AUTO_ANDROID=0)”
AUTO_GUI=0 → call deep-link smoke without multi-round GUI (or set GUI_ROUNDS=0)

Vanilla layers (detail)

Layer	What	Tooling
A — Install	F-Droid or from-source APK	`adb install`
B — Entry (shortcut)	`taler://withdraw/…` / `taler://pay…`	`adb am start -a VIEW`
C — Graphical UI	Confirm / ToS / Pay taps; ANR Wait	`uiautomator` + `lib_ui.py` / chain
D — Evidence	Screenshots, XML, logcat, URIs	`out*/`

Legitimate shortcuts

Shortcut	Replaces
Deep-link withdraw/pay	Camera QR / opening paywall
Host `POST` template → pay URI	Browser shop checkout UI
Label-list taps	Human reading button text
Skip full ToS scroll	Tap Accept if shown

Scripts

Script	Role
`run-android-pay-smoke.sh`	Hybrid: install + deep-link + light taps
`run-android-gui-smoke.sh`	Multi-round GUI drive
`run-goa-gui-chain.sh`	Multi mint/withdraw/pay (gui-workflows port)
`run-android-build-and-smoke.sh`	Build git ref (branch/tag) + smoke (`GUI=1` optional)
`run-android-variant-matrix.sh`	published + stable-self + master (compare builds)
`start-android-emulator.sh`	Start AVD (headless default, SwiftShader)
`lib_android_env.sh`	Flags, PATH, `android_ensure_device`
`lib_ui.py`	Dump/tap/ANR helpers

Build variants (anti–“weird local build”)

Variant	Source	Severity	Purpose
stable-self	only rebuild of current stable tag	WARN	Self-build vs published for one release
published	F-Droid current APK	≤14d → BLOCKER, else WARN	What users install
older / milestones	F-Droid APK ~3 / 6 / 9 / 12 mo	always WARN	No self-build of old tags
master	`origin/master` rebuild	WARN	Tip — never hard-blocks
fix (optional)	inference branch	soft	GOA automation fixes

Self-build: current stable only (plus master/fix if requested) — not older releases.
Blocker window: releases ≤ 14 days.
Milestones: nearest tags to 90/180/270/365d with a still-hosted F-Droid APK.

Stacks under test

Stack	Withdraw	Pay
GOA	explorer mint / `demo-withdraw.json` @ bank.hacktivism.ch	goa-shop templates / Paivana pay-template
stage	explorer / demo-withdraw @ stage.bank…	fermes / jardin public templates

Lageübersicht GOA + stage (as-is survey · 2026-07-17 ~22:05–22:18)

Device: headless emulator-5554 · host ~3.7 GiB RAM (often <300 MiB free) · timeout per leg ≤420 s.
Legs: Abheben + Bezahlen (DO_WITHDRAW=1 DO_PAY=1). Artefakte: out-survey-20260717-220527/ (gitignored).

Varianten

Variante	Quelle	Bemerkung
stable (published)	F-Droid `net.taler.wallet.fdroid` 1.6.1 / 854	as-is
master as-is	rebuild `origin/master` @ `f65a976c` → `.fdroid.debug`	as-is, no patches
ältere Releases (3/6/9/12 mon)	F-Droid APKs für `1.5.0`/`1.3.0`/`1.1.0`/`1.0.8`	nicht auffindbar (HTTP miss) → SKIP (kein Selbstbau älterer Tags)
master + inference (extra)	local branch `local/master-with-inference` @ `3ebe8b09`	merges `fix-bank-withdraw-auto-exchange` + `fix-withdraw-spinner-fallback` · not pushed

Was pro Stack steht (Infra)

Check	goa / hacktivism	*stage / .lefrancpaysan**
Bank `…/intro/demo-withdraw.json` → `taler://withdraw/…`	OK	OK
Pay entry	paivana `pay-template` OK	fermes `panier-legumes` POST → `taler://pay/…` OK
adb `VIEW` Intent delivery	OK	OK
Unattended Confirm/Abheben/Pay GUI	FAIL (ANR)	FAIL (ANR)
wallet-core prepare/accept withdraw in logcat	not seen	not seen

Fazit as-is: Beide Stacks liefern die Eingänge (Withdraw- + Pay-URIs). Die GUI/wallet-core-Strecke ist auf diesem Emulator für alle getesteten App-Varianten (stable, master, inference) gleich tot — System UI / Android System ANR, keine brauchbaren Taps. Das ist kein Stack-Unterschied GOA vs stage und kein belastbarer App-Versions-Vergleich.

Inference-Patch-Versuch (lokal, kein Push)

Weil nichts der as-is-Varianten wallet-core-grün war, wurde zusätzlich gebaut:

taler-android branch: local/master-with-inference   # NOT pushed
base:     origin/master
merged:   origin/dev/hernani-inference/fix-bank-withdraw-auto-exchange
          origin/dev/hernani-inference/fix-withdraw-spinner-fallback
commit:   3ebe8b091379
APK:      apks/wallet-master-inference-3ebe8b091379.apk (local)

Stack	Inference smoke	Besser als master/stable?
goa	exit 10, ANR, no withdraw core	Nein
stage	exit 10, ANR, no withdraw core	Nein

Kein grünes Inference-Signal auf diesem Host → wir können nicht belegen, dass die Patches Withdraw/Pay „retten“.
Ebenso können wir nicht belegen, dass master ohne Patches „schuld“ ist: die Umgebung erreicht wallet-core gar nicht.

Wenn später auf Gerät/mehr RAM die Inference-APK plötzlich grün und master/stable rot ist:
das ist der klare Fix-Hinweis — Patches aus dev/hernani-inference/* upstreamen / in master holen.
Heute: noch nicht der Fall; primärer Blocker = Emulator/RAM/ANR.

Nächste sinnvolle Schritte (später)

Physisches Gerät oder Host ≥6–8 GiB free RAM
Nur eine Wallet-Package-ID installiert (kein Open-with)
Survey wiederholen: stable · master · local/master-with-inference auf goa + stage
Ältere F-Droid-APKs nur wenn wieder gehostet; kein Selbstbau alter Tags

Upstream branches (`taler-android` `dev/hernani-inference/*`)

Branch	Role
`gui-workflows`	macOS emulator helpers + original `goa-chain-emu.sh`
`fix/bank-withdraw-auto-exchange`	Minimal GOA exchange auto-add (default build branch)
`fix/withdraw-spinner-fallback`	Spinner + OIM; use if spinner still hangs
`experimental-oim*`	Optional cash UI
