技巧

对特定测试文件禁用隔离

为每个 projects 配置项设置 isolate 参数，禁用特定文件的隔离功能，从而加速测试运行速度。

vitest.config.ts

import { defineConfig } from 'vitest/config'

export default defineConfig({
  test: {
    projects: [
      {
        // 禁用隔离的单元测试
        name: 'Unit tests',
        isolate: false,
        exclude: ['**.integration.test.ts'],
      },
      {
        // 集成隔离的测试
        name: 'Integration tests',
        include: ['**.integration.test.ts'],
      },
    ],
  },
})

并行与串行测试文件

可以通过 projects 配置项，将测试文件划分为并行和串行两组：

vitest.config.ts

import { defineConfig } from 'vitest/config'

export default defineConfig({
  test: {
    projects: [
      {
        name: 'Parallel',
        exclude: ['**.sequential.test.ts'],
      },
      {
        name: 'Sequential',
        include: ['**.sequential.test.ts'],
        fileParallelism: false,
      },
    ],
  },
})
