Improves an existing behavior

Compatibility

• This is a breaking change

Feature description

Axios' latest version changed the underlying adapter configuration.

Using axios v1.5.0 with msw needs an extra line of code in the test setup.

For example: setup-tests.ts

import axios from 'axios'
import { afterAll, afterEach, beforeAll } from 'vitest'
import { server } from './mocks/server'

beforeAll(() => {
  axios.defaults.adapter = 'xhr'
  server.listen({ onUnhandledRequest: 'warn' })
})

afterEach(() => server.resetHandlers())
afterAll(() => server.close())

Have to use axios.defaults.adapter = 'xhr'. Otherwise, msw interception would not work.

Hi, @zoltan-nz. Thanks for raising this.

MSW should intercept Axios requests regardless which adapter you're using. Can you please submit a reproduction repository when it fails to do so? We've got some integration tests with Axios, I'd love to add your use case to them to prevent issues like this. Thanks.

@kettanaito Thank you! Meanwhile, Axios fixed the issue, and with axios v1.5.1 everything is back to normal. ;)
