 SQLSpec provides tools for both unit and integration testing of database code.
 
-Mock Adapter for Unit Tests
----------------------------
-
-``MockSyncConfig`` and ``MockAsyncConfig`` use an in-memory SQLite backend with
-optional dialect transpilation. Write SQL in your production dialect (PostgreSQL,
-MySQL, Oracle) and it gets transpiled to SQLite before execution.

-
-Key features:
-
-- ``target_dialect`` accepts ``"postgres"``, ``"mysql"``, ``"oracle"``, or ``"sqlite"``
-- SQL is automatically transpiled to SQLite for execution
-- No external database required -- runs entirely in-memory
-- Supports ``initial_sql`` parameter for schema setup on connection create
-
-Integration Test Patterns
--------------------------
-
-For integration tests against real databases, use the standard ``SQLSpec`` +
-adapter config pattern with temporary databases.
