allowOnly

Type: boolean
Default: !process.env.CI
CLI: --allowOnly, --allowOnly=false

By default, Vitest does not permit tests marked with the only flag in Continuous Integration (CI) environments. Conversely, in local development environments, Vitest allows these tests to run.

INFO

Vitest uses std-env package to detect the environment.

You can customize this behavior by explicitly setting the allowOnly option to either true or false.

vitest.config.jsCLI

import { defineConfig } from 'vitest/config'

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

bash

vitest --allowOnly

When enabled, Vitest will not fail the test suite if tests marked with only are detected, including in CI environments.
