browser.provider

• 类型: BrowserProviderOption

provider 工厂的返回值。你急可以从 @vitest/browser-<provider-name> 导入工厂函数，或创建自定义 provider：

import { playwright } from '@vitest/browser-playwright'
import { webdriverio } from '@vitest/browser-webdriverio'
import { preview } from '@vitest/browser-preview'

export default defineConfig({
  test: {
    browser: {
      provider: playwright(),
      provider: webdriverio(),
      provider: preview(),
    },
  },
})

要配置 provider 如何初始化浏览器，你可以将选项传递给工厂函数：

import { playwright } from '@vitest/browser-playwright'

export default defineConfig({
  test: {
    browser: {
      // 所有实例共享的 provider 配置项
      provider: playwright({
        launchOptions: {
          slowMo: 50,
          channel: 'chrome-beta',
        },
        actionTimeout: 5_000,
      }),
      instances: [
        { browser: 'chromium' },
        {
          browser: 'firefox',
          // 仅针对单个实例的覆盖配置
          // 不会与父级配置项合并
          provider: playwright({
            launchOptions: {
              firefoxUserPrefs: {
                'browser.startup.homepage': 'https://example.com',
              },
            },
          })
        }
      ],
    },
  },
})

自定义 Provider advanced

高级 API

自定义 provider API 处于高度实验阶段，可能会在小版本之间发生变化。如果你只需要在浏览器中运行测试，请使用 browser.instances 选项替代。

export interface BrowserProvider {
  name: string
  mocker?: BrowserModuleMocker
  readonly initScripts?: string[]
  /**
   * @experimental 启用文件级并行化
   */
  supportsParallelism: boolean
  getCommandsContext: (sessionId: string) => Record<string, unknown>
  openPage: (sessionId: string, url: string) => Promise<void>
  getCDPSession?: (sessionId: string) => Promise<CDPSession>
  close: () => Awaitable<void>
}
