 ## CI/CD (Drone)
 
-The project uses Drone CI (`.drone.yml`) with five pipelines:
+The project uses Drone CI (`.drone.yml`). Note: `server_build_and_test` and `check_for_formatting` pipelines are currently commented out.
 
 **On push to main:**
-1. **`server_build_and_test`**: Builds the server (`npm ci` + `npm run build`) and runs Jest tests (`npm run test`)
-2. **`check_for_formatting`**: Checks Prettier formatting across all workspaces (`npm run check_format`)
-3. **`deploy_latest`**: Builds Docker image, pushes to Gitea Container Registry (`gitea.gilmour109.de/gilmour109/calchat-server:latest`), then SSHs into VPS (`10.0.0.1`) to pull and restart via `docker compose`. Depends on both pipelines above passing first.
+1. **`deploy_latest`**: Runs E2E testing pipeline with ephemeral infrastructure:
+   - **`deploy_test_backend`**: Deploys server to k3s cluster (`192.168.178.201`) using `kubernetes/manifest.yml` with commit-based naming (`e2e<sha8>`)
+   - **`create_e2e_vm`**: Provisions ephemeral Android emulator VM on Proxmox via OpenTofu (`tofu/e2e/`)
+   - **`run_e2e_tests`**: SSHs into VM, runs `scripts/e2e-test.sh` (clones repo, starts emulator + Expo + Appium, executes E2E tests). VM IP derived from build number: `192.168.178.$((211 + BUILD_NUMBER % 44))`
+   - **`notify_failure`**: Sends email notification on E2E failure
+   - **`destroy_e2e_vm`**: Tears down VM via `tofu destroy` (runs on success and failure)
+   - **`cleanup_k3s`**: Deletes test backend resources from k3s (runs on success and failure)
+   - Docker image build/push and APK build/upload are currently commented out
+   - Uses `e2e-tools` Docker image (`gitea.gilmour109.de/gilmour109/e2e-tools:latest`)
 
-**On tag:**
-4. **`upload_tag`**: Builds Docker image tagged with the git tag (`${DRONE_TAG}`), pushes to registry, then deploys to k3s cluster (`192.168.178.201`) via SSH using `envsubst` with a Kubernetes manifest template.
+**On tag** (`upload_tag`) and **on promote** (`upload_commit`): Currently commented out. Previously deployed to k3s and built APK releases.
 
-**On promote:**
-5. **`upload_commit`**: Builds Docker image tagged with short commit SHA (first 8 chars), pushes to registry, then deploys to k3s cluster (`192.168.178.201`) via SSH using `envsubst` with a Kubernetes manifest template.
+### E2E CI Infrastructure
+
+```
+scripts/
+└── e2e-test.sh           # E2E test runner script (emulator + Expo + Appium)
+tofu/e2e/                  # OpenTofu config for ephemeral Proxmox VMs
+kubernetes/manifest.yml    # k3s manifest template for test backend (uses envsubst: $NAME, $TAG, $COMMIT)
+```
+
+**`scripts/e2e-test.sh`**: Orchestrates E2E test execution inside an ephemeral VM. Supports two modes:
+- **CI mode**: Clones repo, installs deps, starts Android emulator, Expo, Appium, runs tests
+- **Local mode** (`--local`): Uses existing repo checkout, optional `--api-url` override
 
 ## Testing
 
-Server uses Jest with ts-jest for unit testing. Config in `apps/server/jest.config.js` ignores `/node_modules/` and `/dist/`.
+### Server Unit Tests
+
+Jest with ts-jest for unit testing. Config in `apps/server/jest.config.js` ignores `/node_modules/` and `/dist/`.
 
 **Existing tests:**
 - `src/utils/password.test.ts` - Tests for bcrypt hash() and compare()
 - `src/utils/recurrenceExpander.test.ts` - Tests for expandRecurringEvents() (non-recurring, weekly/daily/UNTIL recurrence, EXDATE filtering, RRULE: prefix stripping, invalid RRULE fallback, multi-day events, sorting)
 
+### E2E Tests (Client)
+
+WebdriverIO + Appium for Android E2E testing. Tests run sequentially (`--runInBand`) sharing a singleton Appium driver.
+
+**Two execution modes:**
+- **Dev Client mode** (local): Connects to running Expo app (`host.exp.exponent`), `noReset: true`
+- **APK mode** (CI): Installs APK via `APK_PATH` env var, `noReset: false`
+
+**Running locally:**
+```bash
+# Terminal 1: Start Appium server
+appium
+# Terminal 2: Start Expo dev server on Android emulator
+npm run android -w @calchat/client
+# Terminal 3: Run E2E tests
+npm run test:e2e -w @calchat/client
+```
+
+**Environment variables** (`apps/client/e2e/.env`):
+```
+TEST_USER=test              # Login credentials for tests
+TEST_PASSWORD=test
+DEVICE_NAME=emulator-5554   # Android device/emulator
+APPIUM_HOST=localhost
+APPIUM_PORT=4723
+```
+
+**Element selection:** Uses Android UiAutomator2 with `resource-id` selectors (React Native maps `testID` → `resource-id` on Android).
+
+**testID conventions:** Components with testID support: `AuthButton`, `BaseButton`, `ChatBubble`, `CustomTextInput`, `ProposedEventCard`. Key testIDs: `login-title`, `login-identifier-input`, `login-password-input`, `login-button`, `login-error-text`, `tab-chat`, `tab-calendar`, `tab-settings`, `chat-message-input`, `chat-send-button`, `chat-bubble-left`, `chat-bubble-right`, `settings-logout-button`, `event-accept-button`, `event-reject-button`.
+
+**Existing E2E tests:**
+- `01-app-launch.test.ts` - App startup, detects login or auto-logged-in state
+- `02-login.test.ts` - Empty field validation, invalid credentials error, successful login
