+## Test Architecture
+
+Tests run against the real Flask server with a separate test database seeded with deterministic data. When Playwright starts, it:
+
+1. Seeds a test database (`e2e_test_dogshelter.db` in the server directory) with known dogs and breeds
+2. Starts the Flask server using the test database
+3. Starts the Astro dev server pointing at the Flask server
+4. Runs all e2e tests against the live application
+
+The test data is defined in `../server/utils/seed_test_database.py`.
+
 ## Test Coverage
 
 The tests cover the following core functionality:
 
 ### Homepage Tests
 - Page loads with correct title and content
 - Dog list displays properly
-- Loading states work correctly
-- Error handling for API failures
 
 ### About Page Tests
 - About page content displays correctly
 - Navigation back to homepage works
 
 ### Dog Details Tests
 - Navigation from homepage to dog details
+- Full dog details display correctly
 - Navigation back from dog details to homepage
 - Handling of invalid dog IDs
 
 ### API Integration Tests
-- Successful API responses
-- Empty dog list handling
-- Network error handling
+- Dogs render correctly on the homepage
+- Dog details render correctly
+- 404 handling for non-existent dogs
+- Navigation from card to detail page
 
 ## Configuration
 
-Tests are configured in `../playwright.config.ts` and automatically start the application servers using the existing `scripts/start-app.sh` script before running tests.
