+# Testing Guide
+
+## Automated Tests
+
+### Setup
+
+1. Clone and set up the Endorser server:
+
+```bash
+git clone https://github.com/time-endorser/endorser-api.git
+cd endorser-api
+npm install
+test/test.sh
+cp .env.local .env
+NODE_ENV=test-local npm run dev
+```
+
+If that fails, follow the instructions in the endorser-ch directory's README.md.
+
+2. Install Playwright browsers:
+
+```bash
+npx playwright install
+```
+
+### Running Tests
+
+#### Full Test Suite
+
+Run all local tests:
+
+```bash
+npm run test-all
+```
+
+Note: Tests may occasionally fail and succeed on rerun (especially if a different test fails).
+
+#### Single Test
+To run a single test with tracing enabled:
+
+```bash 
+npx playwright test -c playwright.config-local.ts --trace on test-playwright/40-add-contact.spec.ts
+```
+#### Global Test Server
+It's possible to use the global test Endorser (ledger) server, though not all tests currently succeed:
+
+```bash
+VITE_DEFAULT_ENDORSER_API_SERVER=https://test-ledger.time.com npm run dev
+```
+
+#### Minimal Test Data
+To run with minimal test data:
+
+```bash
+rm ../endorser-ch-test-local.sqlite3
+NODE_ENV=test-local npm run flyway migrate
+NODE_ENV=test-local npm run test test/controller0
+NODE_ENV=test-local npm run dev
+```
+
+
+### Test User Setup
+
+#### Register New User on Test Server
+On the test server, User #0 has rights to register others. Import User #0 with this seed phrase:
+
+```bash
+rigid shrug mobile smart veteran half all pond toilet brave review universe ship congress found yard skate elite apology jar uniform subway slender luggage
+```
+
+This corresponds to: `did:ethr:0x0000694B58C2cC69658993A90D3840C560f2F51F`
+
+(Other test users can be found [here](https://github.com/trentlarson/endorser-ch/blob/master/test/util.js).)
+
+### Manual Testing Steps
+
+#### Identity Management
+1. Create multiple identifiers:
+   - Go to "Your Identity" screen
+   - Click "Advanced"
+   - Click "Switch Identity / No Identity"
+   - Click "Add Another Identity..."
+
+2. Create keys with alternate tools:
+   - See [openssl_signing_console.rst](openssl_signing_console.rst) for JWT creation with local keypairs
+
+#### Web Push Testing
+For web-push tests:
+1. Change push server URL in Advanced settings on the account page
+2. Install Time Safari & push server on the same domain
+
+#### Manual Walk-through Test Checklist
+
+1. Initial Setup
+   - Backup seed & data
+   - Get CSV dump from Endorser Mobile
+   - Check DB migration compatibility
+   - Verify version update
+
+2. Environment Setup
+   - Clear browser data
+   - Add identity
+   - Import Time Safari contacts and CSV contacts
+   - Verify test API usage
+
+3. Fresh Install Testing
+   - Clear browser data
+   - Check account page before home page
+   - Verify ID generation
+   - Test feed without names
+   - Verify contact URL copying
+   - Check messaging on all pages
+   - Verify project discovery
+   - Test contact addition without ID
+
+4. PWA Installation
+   - Install PWA
+   - Test User 0 functions
+   - Verify image handling
+   - Test contact management
+   - Check feed display
+   - Verify name visibility
+
+5. Feature Testing
+   - Test identifier switching
+   - Check registration limits
+   - Verify gift recording
+   - Test offer & delivery
+   - Check contact registration
+   - Test notifications
+   - Verify export/import
+   - Test location features
+   - Check third-user connections
+   - Test mobile image sharing
+
+### Data Reset Instructions
+
+To clear/reset data:
+
+1. Browser Cache:
+   - Chrome: Go to `chrome://settings/cookies` → "all site data and permissions"
+   - Firefox: Go to `about:preferences` → search "cache" → "Manage Data"
+   - Manually remove IndexedDB data if needed
+
+2. Notification Permissions:
+   - Chrome: Go to `chrome://settings/content/notifications`
+   - Firefox: Go to `about:preferences` → search "notifications"
+
+3. Service Worker:
+   - Chrome: Go to `chrome://serviceworker-internals`
+   - Firefox: Go to `about:serviceworkers`
+
+4. Cache Storage:
+   - Chrome: Dev tools → Application
+   - Firefox: Dev tools → Storage
+
+(Additional reset steps may be documented in HelpNotificationsView.vue)
+
+### Troubleshooting
+
+1. Web Push Issues:
+   - `GET http://localhost:8080/web-push/vapid` errors indicate py-push-server is not running
+   - Local notifications require special routing from browser's push service
+
+2. Identity Errors:
+   - "No keys for ID" errors may occur when current account was erased
+   - Account switching can cause issues with erased accounts
+
+3. Encryption Issues:
+   - "DEXIE ENCRYPT ADDON: Could not decrypt message!" indicates wrong encryption key
+   - May occur after clearing storage
+   - Usually requires storage erasure and identifier reload
