Vitest

命令行界面。 ​

命令 ​

vitest ​

在当前目录启动 Vitest。在开发环境中会自动进入监视模式，在 CI（或非交互式终端）中会自动进入运行模式。

你可以传递一个额外的参数作为要运行的测试文件的过滤器。例如：

bash
vitest foobar

将只运行路径中包含 foobar 的测试文件。此过滤器仅检查包含关系，不支持正则表达式或 glob 模式（除非你的终端在 Vitest 接收过滤器之前处理了它）。

自 Vitest 3 起，你还可以通过文件名和行号指定测试：

bash
$ vitest basic/foo.test.ts:10

WARNING

注意，Vitest 需要完整的文件名才能使此功能正常工作。它可以相对于当前工作目录，也可以是绝对文件路径。

bash
$ vitest basic/foo.js:10 # ✅
$ vitest ./basic/foo.js:10 # ✅
$ vitest /users/project/basic/foo.js:10 # ✅
$ vitest foo:10 # ❌
$ vitest ./basic/foo:10 # ❌

目前 Vitest 也不支持范围：

bash
$ vitest basic/foo.test.ts:10, basic/foo.test.ts:25 # ✅
$ vitest basic/foo.test.ts:10-25 # ❌

vitest run ​

执行单次运行，不进入监视模式。

vitest watch ​

运行所有测试套件，但监视更改并在更改时重新运行测试。与不带参数调用 vitest 相同。在 CI 中或当 stdin 不是 TTY（非交互式环境）时将回退到 vitest run。

vitest dev ​

vitest watch 的别名。

仅运行覆盖一系列源文件的测试。适用于静态导入（例如，import('./index.js') 或 import index from './index.js），但不适用于动态导入（例如，import(filepath)）。所有文件应相对于根文件夹。

适合与 lint-staged 或你的 CI 设置一起运行。

bash
vitest related /src/index.ts /src/hello-world.js

TIP

请记住，Vitest 默认以监视模式运行。如果你使用 lint-staged 之类的工具，还应传入 --run 选项，使命令可以正常退出。

.lintstagedrc.js
js
export default {
  '*.{js,ts}': 'vitest related --run',
}

vitest bench ​

只运行用于比较性能结果的基准测试。

vitest init ​

vitest init <name> 可用于设置项目配置。目前，它仅支持 browser 值：

bash
vitest init browser

vitest list ​

vitest list 命令继承所有 vitest 选项以打印所有匹配测试的列表。此命令忽略 reporters 选项。默认情况下，它将打印所有匹配文件过滤器和名称模式的测试名称：

shell
vitest list filename.spec.ts -t="some-test"
txt
describe > some-test
describe > some-test > test 1
describe > some-test > test 2

你可以传递 --json 标志以 JSON 格式打印测试或将其保存到单独的文件中：

bash
vitest list filename.spec.ts -t="some-test" --json=./file.json

如果 --json 标志没有接收值，它将把 JSON 输出到 stdout。

你还可以传递 --filesOnly 标志仅打印测试文件：

bash
vitest list --filesOnly
txt
tests/test1.test.ts
tests/test2.test.ts

从 Vitest 5 开始，vitest list 会通过静态解析测试文件来收集测试，而不是运行这些文件。传入 --no-static-parse 可改为运行文件。Vitest 会以有限并发度解析测试文件，默认值为 os.availableParallelism()。可以通过 --static-parse-concurrency 选项更改并发度。

vitest doctor ​

vitest doctor 会通过在每种候选配置下运行测试套件，测量在替代配置下测试套件的运行速度可以提升多少。候选配置根据当前配置选定：

bash
vitest doctor
结果（每种配置取 3 次运行中的最短时间）

  基准（pool: forks · isolate: true）     4.08s
  pool: 'threads'                         3.64s (-11%)
  pool: 'vmThreads'                       1.33s (-67%)
  isolate: false                          1.28s (-69%)

建议：pool: 'vmThreads' (-67%)

  // vitest.config.ts
  import { defineConfig } from 'vitest/config'

  export default defineConfig({
    test: {
      pool: 'vmThreads', // 在此套件中测得快 67%
    },
  })

isolate: false 候选配置还会通过以随机文件顺序运行两次测试套件进行额外验证：如果任何测试依赖隔离，该候选配置会被报告为失败，而不会被推荐。当多个候选配置与最快配置相差不大时，doctor 会优先选择能够保留文件级隔离的配置。

Doctor 还会在获胜配置的基础上测试较低的 maxWorkers 值：每个 worker 都会将其转换请求通过同一个主线程 Vite 服务器处理，因此超过某个数量后，增加 worker 会使运行变慢而不是变快。Doctor 从当前 worker 数量的一半开始，只要测试套件至少快 5%，就会继续将数量减半，并在建议中包含获胜的值。

在 DOM 或自定义环境中运行的测试套件，会分别在 vmThreads 和 vmForks 两个 VM 池下进行测量：它们让每个 worker 保留一个环境，从而摊销环境创建成本，同时仍为每个文件提供全新的 VM 上下文。vmForks 使用子进程而非 worker 线程；每个子进程都有自己的堆和垃圾回收器，因此哪个池更快取决于测试套件。对于无法在 worker 线程中运行的套件，应使用 VM 选项 vmForks。

如果安装了 jsdom，运行 jsdom 的项目也会在 environment: 'happy-dom' 下进行测量。该替换会针对每个项目单独应用；使用其他环境的项目会保留原环境。happy-dom 与 jsdom 采用不同的 DOM 实现，因此在采用此替换方案前，应验证依赖布局或导航功能的测试。当 fs 模块缓存 关闭时，doctor 会在一次不计时的预热运行（用于填充缓存）之后测量 fsModuleCache: true，因此报告的时间就是重复运行时实际付出的时间。

每次测量都会运行完整的测试套件，包括浏览器项目：isolate: false 也会影响浏览器模式。无法影响浏览器项目的候选配置（pool、environment、fs 模块缓存）会根据仅运行 Node 端项目的结果选定。

失败的候选配置会附带其错误信息摘录。如果测试套件在当前配置下失败，doctor 会中止并显示错误：它需要一个通过测试的基准配置才能进行比较。

较短的测试套件会被多次测量，并报告其中的最佳时间，因此比较结果能够反映预热后的稳定状态。Doctor 会多次运行完整的测试套件，因此所需时间是普通运行时间的数倍。有关每个候选配置背后权衡的详细信息，请参阅改进性能。

即使没有候选配置可供比较，doctor 也会测量并报告基准配置。在 vm pool 上的配置还会与 pool: 'threads' 和 isolate: false 进行额外比较，该配置同样会复用 worker，但会在文件之间共享模块状态；已经使用其中一个 vm pool 的配置仍会在另一个 vm pool 下进行测量。

Shell 自动补全 ​

Vitest 为命令、选项和选项值提供 Shell 自动补全，由 @bomb.sh/tab 提供支持。

设置 ​

要在 zsh 中永久设置，请将此添加到你的 ~/.zshrc：

bash
# 添加到 ~/.zshrc 以实现永久自动补全（其他 shell 也可以这样做）
source <(vitest complete zsh)

包管理器集成 ​

@bomb.sh/tab 与包管理器集成。直接运行 vitest 时自动补全生效：

bash
npm vitest <Tab>
bash
npm exec vitest <Tab>
bash
pnpm vitest <Tab>
bash
yarn vitest <Tab>
bash
bun vitest <Tab>

对于包管理器自动补全，你应该单独安装 Tab 的包管理器补全。

选项 ​

TIP

Vitest 支持 CLI 参数 的驼峰式和短横线式。例如，--passWithNoTests 和 --pass-with-no-tests 都有效（--no-color 和 --inspect-brk 除外）。

Vitest 还支持不同的指定值的方式：--reporter dot 和 --reporter=dot 都有效。

如果选项支持值数组，你需要多次传递该选项：

vitest --reporter=dot --reporter=default

布尔选项可以用 no- 前缀否定。将值指定为 false 也有效：

vitest --api=false

Start Vitest without running tests. Tests will be running only on change. If browser mode is enabled, the UI will be opened automatically. This option is ignored when CLI file filters are passed. (default: false)

listTags ​

  • CLI: --listTags [type]

List all available tags instead of running tests. --list-tags=json will output tags in JSON format, unless there are no tags.

clearCache ​

  • CLI: --clearCache

Delete all Vitest caches, including the fsModuleCache, without running any tests. This will reduce the performance in the subsequent test run.

Print a hint when re-creating a DOM environment for every test file dominates the run and a vm pool would set it up once per worker. (default: true)

experimental.diagnostics.import ​

Print a hint when test files repeatedly evaluate the same module graph (typical for barrel-file imports) and isolate: false would evaluate it once per worker. (default: true)

shard ​

  • 类型: string
  • 默认值: 已禁用

要执行的测试套件分片，格式为 <index>/<count>，其中

  • count 是一个正整数，分割部分的数量
  • index 是一个正整数，分割部分的索引

此命令将所有测试分为 count 个相等的部分，并仅运行恰好位于 index 部分的那些测试。例如，要将测试套件分为三部分，请使用此命令：

sh
vitest run --shard=1/3
vitest run --shard=2/3
vitest run --shard=3/3

WARNING

你不能在启用 --watch 的情况下使用此选项（开发模式下默认启用）。

TIP

如果在未指定输出文件的情况下使用 --reporter=blob，默认路径将包含当前分片配置以及来自 VITEST_BLOB_LABEL 的 blob 标签，或来自 blob reporter 的 label 选项，以避免与其他 Vitest 进程发生冲突。

merge-reports ​

  • 类型: boolean | string

合并指定文件夹中的所有 blob 报告（默认情况下为 .vitest/blob/）。你可以在此命令中使用任意 reporter（除了 blob）：

sh
vitest --merge-reports --reporter=junit
