+# Database Connection Test
+
+Tests basic database CRUD operations using the test database.
+
+## What it verifies
+
+- Database insert operations work
+- Database query operations work
+- Database update operations work
+- Database delete operations work
+- Data retrieval returns correct values
+
+## Prerequisites
+
+- `rspade_test` database exists
+- `rspade` user has access to `rspade_test`
+- Test environment helpers functional
+
+## How to run
+
+```bash
+./run_test.sh              # Full test with database reset
+./run_test.sh --skip-reset # Skip database reset (faster)
+```
+
+## What happens
+
+1. Creates temporary table
+2. Inserts test data
+3. Verifies data was inserted
+4. Queries specific data
+5. Updates data
+6. Verifies update worked
+7. Deletes data
+8. Verifies deletion worked
+9. Cleans up (temporary table auto-removed)
+
+## Expected output
+
+```
+[SETUP] Preparing database connection test...
+[SETUP] Resetting test database...
+[DB RESET] Dropping rspade_test database...
+[DB RESET] Creating rspade_test database...
+[DB RESET] Running migrations...
