cache

Type: boolean
Default: true
CLI: --cache, --no-cache

Store the results of test runs on the file system. Vitest uses them to run failed and longer test files first.

For every test file, Vitest stores whether the file failed, how long it ran and when it ran last. A run that did not execute the whole file (for example, a run filtered with --testNamePattern or cancelled by bail) can mark the file as failed, but it cannot mark it as passed.

You can delete the cache by running vitest --clearCache.

The cache directory is controlled by the Vite's cacheDir option:

import { defineConfig } from 'vitest/config'

export default defineConfig({
  cacheDir: 'custom-folder/.vitest'
})

You can limit the directory only for Vitest by using process.env.VITEST:

import { defineConfig } from 'vitest/config'

export default defineConfig({
  cacheDir: process.env.VITEST ? 'custom-folder/.vitest' : undefined
})

WARNING

The deprecated cache.dir option has no effect anymore. Use cacheDir to change the cache directory.
