Two specs completed in one session. + +--- + +## Key Learnings + +### 1. BATS Fixture Pattern for Offline UI Tests + +**Problem**: UIAutomator `uiautomator dump` requires a live device. Tests would be +flaky/slow without a fixture. + +**Solution**: Capture a real `ui_dump.xml` once, store in `tests/fixtures/`, and +mock the `adb shell uiautomator dump` call in tests using `PATH` override or +function mocking. + +```bash +# In test setup: override adb to return fixture +function adb() { + if [[ "$*" == *"uiautomator dump"* ]]; then + cat tests/fixtures/ui_dump.xml + return 0 + fi + command adb "$@" +} +export -f adb +``` + +**Lesson**: XML fixtures enable fast, deterministic UI parsing tests without device. + +### 2. UIAutomator XML Parsing in Pure Bash + +**Problem**: Parsing XML in Bash is fragile with `grep`/`sed`. + +**Solution**: Use `grep -oP` with Perl regex for attribute extraction. Works reliably +for UIAutomator's flat XML structure (no deep nesting needed). + +```bash +# Extract bounds="[x1,y1][x2,y2]" and compute center +bounds=$(grep -oP 'bounds="\[\K[^\]]+' <<< "$node") +# bounds = "x1,y1][x2,y2" → split on "][" +``` + +**Lesson**: UIAutomator XML is regular enough for grep-based parsing. No need for +`xmllint` dependency. + +### 3. KDE Connect SMS — Graceful Degradation + +**Problem**: `kdeconnect-cli` SMS commands require pairing. Tests must not fail +when device is unpaired. + +**Solution**: Check pairing status first; return structured error with setup +instructions rather than raw CLI error. + +```bash +if ! kdeconnect-cli --list-devices 2>/dev/null | grep -q "paired"; then + out_error "KDE Connect not paired. Run: kdeconnect-cli --pair -d " + exit 2 +fi +``` + +**Lesson**: Exit code 2 = "device/dependency not available" (distinct from exit 1 = +"usage error"). Consistent exit codes make tests reliable. + +### 4. BATS `bats_require_minimum_version` — Don't Run as Bash + +**Problem**: Running `.bats` files directly with `bash` fails with cryptic errors +(`bats_require_minimum_version: command not found`). + +**Solution**: Always run via `bats tests/` or `bats tests/test_foo.bats`. The BATS +runtime provides the `@test`, `run`, `assert_*` functions. + +**Lesson**: Add to project README: "Run tests with `bats tests/`, not `bash tests/`." + +### 5. Scrcpy Headless Mode for Screenshot Automation + +**Problem**: `scrcpy` opens a window by default; CI/automation needs headless. + +**Solution**: `scrcpy --no-display --screenshot-file=path.png` captures a screenshot +without opening a window. Combine with `--serial` for multi-device. + +```bash +scrcpy --serial "$ANDROID_SERIAL" --no-display \ + --screenshot-file "$output_path" 2>/dev/null +``` + +**Lesson**: scrcpy 3.x has `--no-display` + `--screenshot-file` as first-class flags. +No need for `adb exec-out screencap` workarounds. + +### 6. JSON Output Pattern for Shell CLIs + +**Pattern used throughout `fs5`**: Every command supports `--json` flag for +machine-readable output. Implemented via `lib/output.sh`: + +```bash +out_json() { + # $1 = JSON string (pre-built with jq or printf) + echo "$1" +} +out_human() { + # $1 = human-readable string + [[ "${OUTPUT_FORMAT:-human}" == "json" ]] || echo "$1" +} +``` + +**Lesson**: Dual-mode output (human + JSON) makes CLI tools composable with AI agents +and scripts. Use `jq -n` for safe JSON construction. + +--- + +## Anti-Patterns Avoided + +| Anti-Pattern | What We Did Instead | +|---|---| +| `eval` for dynamic adb commands | Array-based `adb_cmd "${args[@]}"` | +| Hardcoded device serial in scripts | `.env` file + `ANDROID_SERIAL` env var | +| `grep` on `adb shell` exit codes | Explicit `adb shell "cmd; echo EXIT:$?"` pattern | +| Monolithic `fs5` script | Modular `lib/adb.sh`, `lib/output.sh`, `lib/input.sh` | + +--- + +## References + +- [BATS Core Docs](https://bats-core.readthedocs.io/) +- [scrcpy README](https://github.com/Genymobile/scrcpy) +- [UIAutomator Docs](https://developer.android.com/training/testing/other-components/ui-automator) +- [KDE Connect CLI](https://userbase.kde.org/KDEConnect) diff --git a/specs/001-android-fs5-management/tasks.md b/specs/001-android-fs5-management/tasks.md index 6db11ab..44736ba 100644 --- a/specs/001-android-fs5-management/tasks.md +++ b/specs/001-android-fs5-management/tasks.md @@ -2,97 +2,80 @@ **Feature**: 001-android-fs5-management **Created**: 2026-03-02 -**Status**: Pending +**Status**: Complete ✅ --- ##
