Best practice for E2E monorepo setup?

[rowanwins]

Hi Vitest community,

We've got a monorepo (using pnpm) and I'm just wondering about whether there are any best practices for an E2E setup with VItest Browser mode?

Currently we have a setup like this which works ok for testing each of our apps independently

apps/
  server/
    tests/
      setup/
         infrastructure.ts
    ts.config.json
    vite.config.ts
    vitest.config.ts
  web-app/
    tests/
    ts.config.json
    vite.config.ts
    vitest.config.ts

However we're looking at implementing some E2E testing utilising both our server and web-app.
In particular I think we're getting a bit stuck working out a good mechanism to startup our server before the E2E tests start.
Currently when we run tests for our server we have have globalSetup file specified within our /server/vitest.config.ts which creates a fresh DB and then starts our server. Because the setup file and tests are initiated within the /server directory it correctly picks up the /server/ts.config.ts and so everything works fine.
We'd ideally like to call that same /server/tests/setup/infrastructure.ts file, however if we try and call it from outside /server (eg from within the /web-app directory) the setup file looses the correct ts.config.json reference.

I don't think this is strictly a Vitest question so much as a ts / paths / config resolution issue.
Providing a test case is a bit tricky sorry but hoping there might be some general advice 😄

Thanks
Rowan
