调研方向

Start by reading the global setup documentation and the existing package layouts under packages/, especially the Java and .NET test runner integrations mentioned in the issue. Then compare how Vitest, Jest, and node:test expose setup, lifecycle, and per-test context APIs. Done means optional packages provide the proposed container declaration and test helpers for all three runners, while respecting that global setup can pass only serialisable connection details.

描述

enhancement minor

What happens

Using a container from a test runner is wired by hand each time. The global setup page in the docs shows the pattern for one shared container:

  • a setup file that starts the container and stores it in a module variable
  • project.provide("redisUrl", ...) and inject("redisUrl") to pass a serialisable value to the tests
  • a teardown export that stops it
  • a config entry pointing at the setup file

Per-file and per-test containers need their own beforeAll/afterAll pairs or await using.

Expected

Small optional packages that turn this into a declaration, for example for Vitest:

// vitest.setup.ts
export default defineContainers({
  redis: () => new RedisContainer("redis:8"),
});

// some.test.ts
const test = withContainers<typeof containers>();
test("stores a value", async ({ redis }) => {
  /* redis.connectionUrl */
});

with equivalents for Jest and node:test.

Where

New packages under packages/, outside packages/testcontainers and packages/modules.

Notes

  • Java ships junit-jupiter and spock integration modules. .NET ships xUnit packages.
  • A global setup runs in a different process from the tests, so only serialisable connection details can cross. That shapes the API.
  • Independent of the core API work.

Dependencies

  • Nothing blocks this. It can start now.
