How to mock default methods?

[arboleya]

Hi, thanks for such a library. I loved it!

How should I mock default methods (not classes), like this one below?

// notify.ts
import needle from 'needle'

// want to mock the `needle` default method

export const notify = async () => {
   return needle( /* ... */ )
}

I was first trying just like the others, but it doesn't work:

// notify.test.ts

import { notify } from './notify'

import * as needleMod from 'needle'
import { ImportMock } from 'ts-mock-imports'


describe(`mock default`, () => {


  it('should mock default', async () => {
    
    const pYes = Promise.resolve(true)
    const needleDefault = m(needleMod, 'default', pYes)

    await notify()

    expect(needleDefault.callCount).to.eq(1) // never called, always = 0

  })

})

I have tried other combinations as per the readme, but without any luck.

Thanks.

Can you provide more information about needle and notify. The way you are mocking default is correct and should work, so more information about how needle is exported and imported is needed.

@EmandM I did more tests with it and it indeed works as expected. The problem, I believe, is that my dependency defines its exports inside conditionals.
