@vitest/expect#

Jest's expect matchers as a Chai plugin.

Usage#

import * as chai from 'chai'
import { JestAsymmetricMatchers, JestChaiExpect, JestExtend } from '@vitest/expect'

// allows using expect.extend instead of chai.use to extend plugins
chai.use(JestExtend)
// adds all jest matchers to expect
chai.use(JestChaiExpect)
// adds asymmetric matchers like stringContaining, objectContaining
chai.use(JestAsymmetricMatchers)
