Quick Start

// fixtures/redis.ts
import type { ServiceFixture } from "@suaveplan/testing-integration/fixture/service-fixture";

export const redisFixture: ServiceFixture<{ url: string }> = {
  name: "redis",
  async start() {
    // start your real Redis container or in-process server
    return { url: "redis://localhost:6379" };
  },
  async stop() { /* stop it */ },
  async healthCheck() { return true; },
};

// vitest.config.ts
import { defineConfig } from "vitest/config";
import { createIntegrationSetup } from "@suaveplan/testing-integration/setup/create-integration-setup";
import { redisFixture } from "./fixtures/redis.js";

const { globalSetup, inject } = createIntegrationSetup({ redis: redisFixture });

export default defineConfig({ test: { globalSetup: [globalSetup] } });
export { inject };

// redis.test.ts
import { beforeEach } from "vitest";
import { inject } from "../vitest.config.js";
import { skipIfUnavailable } from "@suaveplan/testing-integration/helpers/skip-if-unavailable";

beforeEach(skipIfUnavailable("redis"));

it("reads from redis", async () => {
  const { url } = inject("redis"); // typed as { url: string }
  // ...
});

Environment Bridge

The package uses two provide/inject keys as an internal implementation detail:

Key	Type	Description
__integration_configs__	Record<string, Record<string, unknown>>	Config objects keyed by fixture key, populated in global-setup.
__integration_failed__	string[]	Names of fixtures whose start() threw, used by skipIfUnavailable.

Do not read these keys directly — use inject(key) from createIntegrationSetup for configs and skipIfUnavailable(name) for skip guards.

Adding a New testing-integration-<service> Plugin

When creating a sibling fixture package (e.g. @suaveplan/testing-integration-clickhouse):

1. Mirror the vite.config.ts of an existing fixture (e.g. testing-integration-redis). The build.rollupOptions.output block MUST contain all three of preserveModules: true, preserveModulesRoot: "src", and entryFileNames: "[name].js". Without the third line, Vite's lib mode derives the entry filename from the package name and the consumer-facing dist/index.js is never written — the package will appear to build but fail to resolve from any sibling workspace.
2. Run bun run check:fixture-resolves from the repo root to verify the new package resolves. The repo-level CI gate //#check:fixture-resolves (in turbo.json) will fail otherwise.
