+
+## Manual Test Scripts
+
+These scripts are for manual testing with real APIs and data.
+
+### Test Cache and Deduplication
+```bash
+python tests/manual/test_cache_and_dedup.py
+```
+
+**Purpose**: Verify cache mode and deduplication with real data
+
+**What it does**:
+1. Runs a search without cache (fetches from APIs)
+2. Displays statistics (cats found, duplicates removed, cache size)
+3. Runs same search with cache (uses cached data)
+4. Compares performance and results
+5. Shows image embedding deduplication in action
+
+### Test Email Sending
+```bash
+python tests/manual/test_email_sending.py
+```
+
+**Purpose**: Send test emails via configured provider
+
+**What it does**:
+1. Sends welcome email
+2. Sends match notification email with sample data
+3. Verifies HTML rendering and provider integration
+
+**Requirements**: Valid MAILGUN_API_KEY or SENDGRID_API_KEY in `.env`
+
+### Test Semantic Color/Breed Matching
+```bash
+python scripts/test_semantic_matching.py
+```
+
+**Purpose**: Verify 3-tier color and breed matching system
+
+**What it does**:
+1. Tests color mapping with and without vector DB
+2. Tests breed mapping with and without vector DB
+3. Demonstrates typo handling ("tuxado" → "tuxedo", "ragdol" → "Ragdoll")
+4. Shows dictionary vs vector vs fallback matching
+5. Displays similarity scores for fuzzy matches
+
+**What you'll see**:
+- ✅ Dictionary matches (instant)
+- ✅ Vector DB fuzzy matches (with similarity scores)
+- ✅ Typo correction in action
+- ✅ 3-tier strategy demonstration
+
+### Test Framework Directly
+```bash
+python cat_adoption_framework.py
+```
+
+**Purpose**: Run framework end-to-end test
+
+**What it does**:
+1. Initializes framework
+2. Creates sample profile
+3. Executes search
+4. Displays top matches
+5. Shows statistics
+
+---
+
+## Test Configuration
+
+### Fixtures
+
+Common test fixtures are defined in `tests/conftest.py`:
+
+- `temp_db` - Temporary database for testing
+- `temp_vectordb` - Temporary vector store
+- `sample_cat` - Sample cat object
+- `sample_profile` - Sample search profile
+- `mock_framework` - Mocked framework for unit tests
+
+### Environment
+
+Tests use separate databases to avoid affecting production data:
+- `test_tuxedo_link.db` - Test database (auto-deleted)
+- `test_vectorstore` - Test vector store (auto-deleted)
+
+### Mocking
+
+External APIs are mocked in unit tests:
+- Petfinder API calls
+- RescueGroups API calls
+- Email provider calls
+- Modal remote functions
+
+Integration tests can use real APIs (set `SKIP_API_TESTS=false` in environment).
