globalSetup script is executed with wrong CWD

[maxpatiiuk]

Describe the bug

When using vitest.workspace.ts file in a monorepo, the globalSetup script is executed with the CWD set to the monorepo root rather than the package root.

The vite.config.ts is correctly executed with the package root as CWD.

Reproduction

https://stackblitz.com/~/github.com/maxpatiiuk/vitest-wrong-dir

1. Clone this repository & install dependencies (or use Stackblitz):

   git clone https://github.com/maxpatiiuk/vitest-wrong-cwd
   cd vite-wrong-cwd
   npm install

2. Run npx vitest run from monorepo root. See that the vite.config.ts is correctly executed with CWD set to package root. At the same time, globalSetup script is unexpectedly executed with CWD set to the monorepo root.

Is this duplicate of #5277?

[AriPerkkio]

Though global setup is executed in the main thread. Maybe we could do something like

const cwd = process.cwd()
process.chdir(dirname(<project-config-location>))

await import(<project-global-setup>)
process.chdir(cwd)

But would this just cause confusion as other fields of project's configuration are not relative to configuration file's location? 🤔

It indeed appears so - sorry I failed to find that issue when searching for duplicates.

The following seems to be a sufficient workaround for my case. It was just a surprising behavior.

export async function setup(context: GlobalSetupContext): Promise<() => Promise<void>> {
  // Workaround for https://github.com/vitest-dev/vscode/issues/503
  if (process.cwd() !== context.config.root) {
    process.chdir(context.config.root);
  }
 
  // ...rest of global setup
}

We might be able to chdir for globalSetup like AriPerkkio suggested #6706 (comment) since we already does something similar during config loading, but there's still a caveat that we cannot do that for test runner itself #5277 (comment)

In 1.5.0, the process.cwd in the config file is now equal to the directory of that config file. But process.cwd in test files still uses workspace process.cwd.
