foundry-rs 0.5.12

//! SQLite integration tests — exercise the full CRUD stack (SQL builder, migrations,
//! CrudService, validation) without a PostgreSQL instance.
//!
//! All tests use an in-memory SQLite database via `sqlite::memory:`.
//! The schema name in config is set to `main` — the implicit default schema in SQLite —
//! so qualified identifiers like `"main"."users"` resolve correctly.
//!
//! These tests are dialect-agnostic smoke tests. They cover logic that is 0% covered by
//! unit tests (everything that needs a real database), but they do NOT test
//! Postgres-specific features (JSONB, RLS, native UUIDs, named enum types).
