pytest assert to a function that has input inside to type

Question

I'd like to test this function

i = "hello" and DEST should be an input

def INPUT_translator(i):
    trans = Translator()
    DEST = input("Translate to: ")
    il = trans.translate(i, dest=DEST)
    return il.text

what is the correct way to test the function

error when testing

expecting hello as output
