provide & inject (Global Setup)
Start shared services once and pass serializable values to every test file
typescript
// global-setup.ts
import type { TestProject } from 'vitest/node'
export default function setup(project: TestProject) {
project.provide('apiPort', 4000)
}
// any.test.ts
import { inject } from 'vitest'
const port = inject('apiPort') // 4000📌 globalSetup runs in a separate scope; share data via provide/inject
💡 Declare ProvidedContext so inject() is fully typed
⚡ Return a function from setup to tear down after the whole run
🔍 setupFiles run per test file; globalSetup runs once per run
