Breaking Changes

• breaking

  Remove browser from allowed pools inside poolMatchGlob config option. Please, use Vitest workspaces for running tests in the browser.

• breaking

  Move assertion declarations to expect package

  • The change should be minor:

  - declare namespace Vi {
  + declare module 'vitest' {
     interface Assertion<T = any> extends CustomMatchers<T> {}
     interface AsymmetricMatchersContaining extends CustomMatchers {}
  }

Features

• Update mock implementation to support ESM runtime, introduce "vi.hoisted"

  • Bypass ESM import order restriction with vi.hoisted to run code before imports are executed:

  vi.hoisted(() => vi.setSystemTime(new Date(2022, 1, 1)))

  You can also use it to pass variables to vi.mock:

  const { mockedMethod } = vi.hoisted(() => {
    return { mockedMethod: vi.fn() }
  })   
  vi.mock('./path/to/module.js', () => {
    return { originalMethod: mockedMethod }
  })
