unstubEnvs

• Type: boolean
• Default: false

Should Vitest automatically call vi.unstubAllEnvs() before each test.

vitest.config.js

import { defineConfig } from 'vitest/config'

export default defineConfig({
  test: {
    unstubEnvs: true,
  },
})

WARNING

Be aware that this option may cause problems with async concurrent tests. If enabled, the completion of one test will restore all the values changed with vi.stubEnv, including those currently being used by other tests in progress.
