+# SurrealDBFixture
+
+<!-- begin:auto-docs -->
+_(no submodules)_
+<!-- end:auto-docs -->
+## Purpose
+
+`SurrealDBFixture` is an integration test fixture that manages the full lifecycle of a SurrealDB v3 container using testcontainers. It implements the `ServiceFixture<SurrealDBConfig>` interface from `@suaveplan/testing-integration`, enabling consistent startup, health checking, and teardown as part of a `TestEnvironment` or standalone usage.
+
+The fixture supports an env-bridge passthrough mode so developer workstations with live SurrealDB instances can skip container startup entirely — just set the three required environment variables and tests run against the real service without Docker overhead.
+
+## Features
+
+- **Env-bridge passthrough**: when `SURREALDB_URL`, `SURREALDB_USERNAME`, and `SURREALDB_PASSWORD` are all set and non-empty, container startup is bypassed and env values are returned directly.
+- **HTTP health check**: polls `GET /health` on SurrealDB's HTTP port (same port as WebSocket) to verify the service is ready before returning from `start()`.
+- **Random password per run**: generates a new `crypto.randomUUID()` password each time a container starts, preventing credential reuse across test suites.
+- **Injectable container factory**: the `containerFactory` option allows unit tests to swap in a fake container without starting Docker, achieving 100% Istanbul coverage without integration dependencies.
+- **Configurable namespace and database**: override defaults via options to isolate test suites at the logical database level.
+- **Idempotent stop**: calling `stop()` on an already-stopped or passthrough fixture is safe and does not throw.
+
+## Usage: Basic Example
+
+```typescript
+import { SurrealDBFixture } from "@suaveplan/testing-integration-surrealdb";
+
+const fixture = new SurrealDBFixture();
+const config = await fixture.start();
+
+// config.url → "ws://localhost:<randomPort>"
+// config.username → "root"
+// config.password → auto-generated UUID
+// config.namespace → "test"
+// config.database → "test"
+
+await fixture.stop();
+```
+
+## Usage: Advanced Example
+
+```typescript
+import { SurrealDBFixture } from "@suaveplan/testing-integration-surrealdb";
+import Surreal from "surrealdb";
+
+const fixture = new SurrealDBFixture({
+  image: "surrealdb/surrealdb:v3.0.4",
+  namespace: "myapp",
+  database: "integration",
+});
+
+const config = await fixture.start();
+const db = new Surreal();
+await db.connect(config.url);
+await db.use({ namespace: config.namespace, database: config.database });
+await db.signin({ username: config.username, password: config.password });
+
+// run tests…
+
+await db.close();
+await fixture.stop();
+```
+
+## API Reference
+
+### `class SurrealDBFixture`
+
+Implements `ServiceFixture<SurrealDBConfig>`.
+
+#### `constructor(options?: SurrealDBFixtureOptions)`
+
+Creates a new fixture instance. All options are optional.
+
+#### `name: string`
+
+Always `"surrealdb"`. Used by `TestEnvironment` as the registry key.
+
+#### `start(): Promise<SurrealDBConfig>`
+
+Starts the service. Returns the runtime configuration on success. If all three env vars are set, returns passthrough config immediately. Otherwise starts a testcontainers container and waits for the HTTP health endpoint.
+
+#### `stop(): Promise<void>`
+
+Stops the container. No-op in passthrough mode or when `start()` was never called.
+
+#### `healthCheck(): Promise<boolean>`
+
+Returns `true` when `GET http://localhost:<port>/health` returns an OK response. Returns `false` if no container is active or the request fails.
+
+### `interface SurrealDBConfig`
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `url` | `string` | WebSocket URL: `ws://localhost:<port>` |
+| `namespace` | `string` | SurrealDB namespace |
+| `database` | `string` | SurrealDB database name |
+| `username` | `string` | Auth username (always `root` in container mode) |
+| `password` | `string` | Auth password (random UUID in container mode) |
+
+### `interface SurrealDBFixtureOptions`
+
+| Field | Type | Description |
+|-------|------|-------------|
+| `image?` | `string` | Docker image override. Defaults to `surrealdb/surrealdb:v3.0.4`. |
+| `namespace?` | `string` | Namespace override. Defaults to `"test"`. |
+| `database?` | `string` | Database override. Defaults to `"test"`. |
+| `containerFactory?` | `(image: string) => GenericContainer` | Injectable factory for unit testing. When provided, replaces the real `GenericContainer` constructor. |
+
+## Implementation Notes
+
+- **Why HTTP health over WebSocket**: the `/health` HTTP endpoint is simpler to poll and does not require a SurrealDB client package in this fixture. WebSocket handshakes are stateful and require protocol negotiation; plain HTTP is sufficient for readiness signalling.
+- **Why random password per run**: reusing a static password across test runs creates a security surface for tests running in CI with shared Docker networks. UUID-generation via `crypto.randomUUID()` (the Web Crypto API, universally available in modern Bun and Node.js) is both fast and cryptographically random.
+- **Dynamic import of testcontainers**: `GenericContainer` is dynamically imported inside `start()` to keep the module side-effect-free and to allow the `containerFactory` injection path to bypass the import entirely for unit tests that provide their own factory.
+- **Port mapping**: testcontainers allocates an ephemeral host port for each `withExposedPorts()` declaration. `getMappedPort(8000)` retrieves the actual host port after the container starts.
