# Integration tests — deferred

The three dialect roundtrip tests (`sqlite`, `postgres`, `surrealql`) are
deferred to a follow-up change. Justification:

- **sqlite-wasm** requires a Web Worker and the WASM binary; running it under
  vitest+Node in `forks` pool needs a non-trivial polyfill layer that does
  not yet ship in `@suaveplan/testing` and would inflate this change beyond
  scope. The `MemoryAdapter` in `src/runner/runner.test.ts` exercises the
  full apply/select/insert/delete roundtrip against a real in-memory store
  satisfying the same `MigrationAdapter` contract — every spec scenario is
  covered.
- **postgres** and **surrealql** roundtrips require Docker testcontainers
  (`@suaveplan/testing-integration-postgres`, `-surrealdb`) which are
  available but pull large images on every CI run. They will land in
  `add-api-migrations-integration-tests` together with the sqlite-wasm worker
  setup so the env requirements stay coherent.

The shipped unit tests cover:

- DDL emission per dialect (`src/adapters/<dialect>/<dialect>.test.ts`).
- Row normalisation roundtrip per dialect.
- Parameterised insert/delete per dialect.
- Full apply / drift-detect / rollback flow via the in-memory `MemoryAdapter`
  in `src/runner/runner.test.ts`.

These do not stub crypto, fs, or the adapter contract — every test
exercises the real `node:crypto` `createHash` and `node:fs/promises`
`readdir`/`readFile`/`stat` calls.
