How to Test Custom Hook with react testing library

Question

I tried using react-hooks-testing-library but it dosn't seem how handle hooks that use useContext.

import React,{useContext} from 'react'
import {AuthContextData} from '../../AuthContext/AuthContext'
const useAuthContext = () => {
    const {authState} = useContext(AuthContextData) 
    const {isAuth,token,userId,userData} = authState
    return {isAuth,token,userId,userData}
  }
  export default useAuthContext

You have to wrap your hook in a context provider:

let authContext
renderHook(() => (authContext = useAuthContext()), {
  wrapper: ({ children }) => (
    <AuthContextData.Provider value={/* Your value */}>
      {children}
    <AuthContextData.Provider>
  )
})
