monitoring: GUI-AUTOMATION-NOTES + AUTO_ANDROID/AUTO_GUI flags

Document minimal variant; Linux defaults to Android-only automation;
macOS can enable both ecosystems later via flags.

# Automated GUI notes — Android wallet (vanilla level)
# Moved
Goal: tests for **two systems** (GOA / hacktivism and stage TESTPAYSAN) that
exercise the wallet **graphically in the UI** as far as practical, not only
CLI/`adb` deep-links into wallet-core.
## Vanilla level (this tree)
| Layer | What we do | Tooling |
|-------|------------|---------|
| **A — Install** | Install published F-Droid APK **or** APK built from `taler-android` master | `adb install` |
| **B — Entry (shortcut)** | Deliver withdraw / pay as `taler://…` intents | `adb shell am start -a VIEW -d …` |
| **C — Graphical UI** | Dump hierarchy, tap Confirm / ToS / Pay-like buttons, dismiss ANR | `uiautomator dump` + `input tap` (`lib_ui.py`) |
| **D — Evidence** | Screenshots + UI XML + logcat + JSON status | `android-test/out-gui/` |
Scripts:
| Script | Role |
|--------|------|
| `run-android-pay-smoke.sh` | Install + deep-link + light taps (hybrid / CLI-heavy) |
| `run-android-gui-smoke.sh` | **Vanilla GUI path**: deep-link entry + multi-round UI driving |
| `run-android-build-and-smoke.sh` | Build latest source APK → same smoke (set `GUI=1` to call GUI script) |
| `lib_ui.py` | Shared dump/tap/ANR helpers |
```bash
cd scripts/taler-monitoring/android-test
# Published APK, graphical drive, both stacks
STACK=goa ./run-android-gui-smoke.sh
STACK=stage ./run-android-gui-smoke.sh
# From-source APK + GUI
APK_PATH=~/taler/taler-android/wallet/build/outputs/apk/fdroid/debug/wallet-fdroid-debug.apk \
PKG=net.taler.wallet.fdroid.debug \
STACK=goa ./run-android-gui-smoke.sh
```
## Legitimate shortcuts (document, do not hide)
These are **not** full human UX, but they are the same contracts as QR scan /
paywall open on the landings:
| Shortcut | Replaces | Why legitimate |
|----------|----------|----------------|
| `adb` `VIEW` `taler://withdraw/…` | Camera QR scan of communal / demo withdraw | Identical URI payload as landings (`demo-withdraw.json`) |
| `adb` `VIEW` `taler://pay…` / `pay-template/…` | Scan shop/paywall QR or open “pay with Taler” | Same URI merchant/backend would show |
| Host-side `POST …/templates/{id}` then pay URI | Browser shop UI to create order | Stage farmer templates are public; order create is API, pay is still wallet UI |
| Multi-language label list for taps | Human reading the button | Same visible buttons; brittle if copy changes |
| Skip full ToS reading | User scrolling long TOS | Tap “Accept” if shown; no legal review automation |
**Not automated yet (out of vanilla scope):**
- Typing personal bank passwords into the wallet webview
- NFC
- Real camera / vision-based QR
- Biometric unlock
- Full onboarding wizard every time (we force-stop + re-intent)
## Two systems under test
| Stack | Withdraw source | Pay source |
|-------|-----------------|------------|
| **GOA** (`STACK=goa`) | `https://bank.hacktivism.ch/intro/demo-withdraw.json` | `taler://pay-template/taler.hacktivism.ch/instances/goa-shop/paivana` (Paivana) |
| **stage** (`STACK=stage`) | `https://stage.bank.lefrancpaysan.ch/intro/demo-withdraw.json` | Public template e.g. `fermes-des-collines` / `panier-legumes``taler://pay/…` |
Both use the **same** GUI driver (`lib_ui.py`); only URLs and package under test differ.
## GUI driver behaviour (`lib_ui.gui_drive`)
1. Every round: `uiautomator dump` + optional screencap.
2. If **“System UI isnt responding”** → tap **Wait** (prefer over Close).
3. Else try exact taps on Confirm / Withdraw / Accept / Pay / DE/FR synonyms.
4. Else regex partial match on those words.
5. Repeat `GUI_ROUNDS` times (default 10), `GUI_SLEEP` seconds apart.
Success signals (layered):
- **Intent delivered**`am start` OK
- **wallet-core** — logcat `prepareBankIntegratedWithdrawal` / pay-related ops
- **GUI taps** — non-empty `taps` in `gui-*-status.json`
- **Screenshots** — human-readable progress under `gui-withdraw/` / `gui-pay/`
A run can be “vanilla-partial” if intents + some taps succeed but final
balance/settlement is not asserted (settlement still better covered by
`taler-monitoring.sh e2e` CLI wallet).
## Host limits (clementine, 2026-07)
| Constraint | Effect |
|------------|--------|
| ~3.7GiB RAM | Emulator ANRs; GUI rounds often only dismiss ANR |
| Prefer physical phone or ≥68GiB host | Real Confirm/Pay taps complete more often |
| No root required | User SDK + adb + F-Droid/source APK |
## Relation to CLI e2e
| Suite | Strength |
|-------|----------|
| `taler-monitoring.sh e2e` / `ladder` | Full withdraw+pay **settlement** via `taler-wallet-cli` |
| `run-android-gui-smoke.sh` | **Android app UI** surface for the same stacks |
| Combined | CLI = money path green; GUI = app UX green as far as taps go |
## Upstream: `taler-android` `dev/hernani-inference/*`
Branch name is **`hernani-inference`** (not “inferenced”). Remote:
`git@git.taler.net:taler-android.git`.
| Branch | Relevance for automation |
|--------|---------------------------|
| **`dev/hernani-inference/gui-workflows`** | **Primary:** macOS emulator helpers + **GOA GUI chain** (`scripts/goa-chain-emu.sh`, `docs/gui-workflows.md`, `setup-avds.sh`, `start-emulators.sh`). Deep-link + `uiautomator` text taps + bank API mint + shop templates. |
| **`fix/bank-withdraw-auto-exchange`** | App fix: resolve exchange when bank omits it (needed for GOA withdraw UI). |
| **`fix/withdraw-spinner-fallback`** | App fix: stop endless withdraw spinner (+ OIM UI work). |
| **`experimental-oim` / `experimental-oim-pos`** | Experimental cash denomination UI; optional for demos, not required for chain. |
### Port into this tree (Linux-capable)
| Upstream (gui-workflows) | Here (`android-test/`) |
|--------------------------|-------------------------|
| `goa-chain-emu.sh` | **`run-goa-gui-chain.sh`** (goa + stage, Linux paths, explorer secrets as monitoring ladder) |
| `tap_text` / `click_through` | same idea in chain + `lib_ui.py` |
| `mint_withdraw` explorer API | same (Basic → token → POST withdrawals) |
| `mint_pay` public templates | same (goa-shop products / stage fermes templates) |
| `android-env.sh` Homebrew | use `$HOME/Android/Sdk` + system `adb` (see GIT-AUTOMATION-NOTES) |
| macOS-only docs | **Linux supported** for chain/smoke; AVD setup still DIY on Linux |
Open issues mirrored from upstream `ISSUES.md` (gui-workflows):
- **I-and-gui-001** — taps still best-effort; ToS/confirm may need human
- **I-and-gui-003**`EXP_PW_FILE` required for mint
- **I-and-gui-004** — emulator RAM cost (this host ~3.7GiB)
- **I-and-gui-007** — for reliable withdraw GUI, build/install app from **fix/bank-withdraw-auto-exchange** or **fix/withdraw-spinner-fallback**, not plain master alone
### Ground rule (ops)
1. **Bring it to run** first (scripts + live stack).
2. **App code changes only if needed**, and **minimal**.
3. Prefer **existing** `dev/hernani-inference/*` branches over new ones; extend them rather than forking random trees.
### Recommended demo stack (2026-07)
```text
1) taler-android checkout:
dev/hernani-inference/fix-bank-withdraw-auto-exchange
(or fix/withdraw-spinner-fallback for spinner + OIM)
2) ./gradlew :wallet:assembleFdroidDebug # package net.taler.wallet.fdroid.debug
3) Boot emulator / phone (prefer ≥68GiB host RAM; 4GiB → System UI ANR)
4) android-test/run-goa-gui-chain.sh # STACK=goa|stage
```
`run-android-build-and-smoke.sh` defaults `BRANCH=dev/hernani-inference/fix-bank-withdraw-auto-exchange`
so source smokes pick up the GOA exchange auto-add fix without manual checkout.
### Runtime note (clementine)
On ~3.7GiB hosts the emulator often shows **System UI isnt responding** before Confirm is tappable. Chain script now prioritizes **Wait** over hunting Confirm. For a green end-to-end GUI path use a physical device or more RAM — the **mint + deep-link + fix-branch APK** path is otherwise ready.
```bash
# GOA chain (explorer mint + GUI taps)
EXP_PW_FILE=$HOME/src/koopa/koopa-admin-secrets/koopa/host-root/taler-bank/bank-explorer-password.txt \
STACK=goa PKG=net.taler.wallet.fdroid.debug \
./run-goa-gui-chain.sh
# Stage TESTPAYSAN (explorer via stagepaysan SSH if EXP_PW_FILE unset)
STACK=stage ./run-goa-gui-chain.sh
```
## Future upgrades (not required for vanilla)
- Maestro / Appium flows with stable resource-ids
- Explicit wait for text “Withdrawal complete” / balance
- Port Paivana unlock scripts (upstream I-and-gui-002)
- Dual AVD wallet+POS (upstream I-and-gui-008)
- Record video (`adb shell screenrecord`) on failure
## Checklist — “vanille erreicht?”
- [x] Two stacks parameterized (goa / stage)
- [x] Published APK path
- [x] Source-build path (same smoke after build)
- [x] Deep-link shortcuts documented
- [x] Multi-round **graphical** taps (uiautomator)
- [x] GOA-style **chain** (multi withdraw + multi pay) from inference branch
- [x] Screenshots + UI XML + logcat artifacts
- [x] Inference branch mapping documented
- [ ] Fully reliable unattended Confirm→settled on low-RAM emulator (host-limited)
- [ ] App built from withdraw-fix branch by default in build script (optional)
- [ ] Assert final balance in app UI (optional next step)
