/**
|
|
* Postgres-backed end-to-end exercise of the Better-Auth adapter.
|
|
*
|
|
* The test stands up a real Postgres 16 container via
|
|
* `@suaveplan/testing-integration-postgres`, applies Better-Auth's
|
|
* documented schema (user / session / account / verification tables), wires
|
|
* a real Better-Auth instance against the connection, and verifies the
|
|
* register → login → resolve-protected-route flow.
|
|
*
|
|
* The schema is applied by hand-rolled DDL because Better-Auth's migration
|
|
* generator runs as a CLI step out-of-band of the runtime; embedding the
|
|
* canonical table definitions inline keeps the test self-contained.
|
|
*
|
|
* When the Postgres fixture cannot start (no Docker daemon, no testcontainers
|
|
* download, runner pinned to a sandbox without Docker), the suite logs a
|
|
* SKIP marker and exits — the runtime-level invariants are pinned by
|
|
* `src/session/*.test.ts`, `src/provider/*.test.ts`, and the
|
|
* conformance test files, all of which run without external infrastructure.
