 # Claude Code Notes
 
+## Running Tests
+
+Use `bun run test:cov` to run all tests with coverage. This runs both unit tests and e2e tests that require a database connection.
+
+- `bun run test:cov` - Run all tests with coverage (preferred)
+- `bun run test:unit:cov` - Run only unit tests with coverage (no database required)
+
 ## Database Scripts
 
 Use the wrapper scripts instead of running dbmate directly:
