Since vitest 0.30 : SyntaxError: Cannot use import statement outside a module when running tests

[acmichaud]

Describe the bug
When I run ALL the tests using the vscode extension, I get this error

/.../vitest.config.js:2

import { defineConfig } from 'vite'

^^^^^^

SyntaxError: Cannot use import statement outside a module

And the test just runs until I press stop.
The thing is that the debug play button works fine ...

To Reproduce
Here is my configuration :

vitest.config.js

import { defineConfig } from 'vite'
// other imports

export default defineConfig({
//.......
})

Environment

• OS: Windows
• VSCode version: 1.77.3
• Vitest version: 0.30.1
• Vitest plugin version: v0.2.39

I encountered this problem in the my monorepo project, I set type=module in package. json to solve my problem. I don't know if that's gonna solve your problem

{
  "type": "module",   //here
  "scripts": {
       // your code
  }
}

Hi there! This solved the error thx!...

But now I get a new one :(

Test result not found. 
If you set `vitest.commandLine` please check: 
    Did you set `vitest.commandLine` to `run` mode? (This extension requires `watch` mode to get the results from Vitest api)
    Does it have the ability to append extra arguments? (For example it should be `yarn test --` rather than `yarn test`)
Are there tests with the same name?
Can you run vitest successfully on this file? Does it need custom option to run?

Again, the debug tests works fine and also the command line vitest run are working.

I encountered this error as well. Seems like if npx vitest can detect that it is an ESM without the type in package.json, so should this extension.

It worked for me.
