How to create fake text file in Python

Question

How can I create a fake file object in Python that contains text? I\'m trying to write unit tests for a method that takes in a file object and retrieves the text via readl

Answer 1

Or you could implement it yourself pretty easily especially since all you need is readlines():

class FileSpoof:
     def __init__(self,my_text):
         self.my_text = my_text
     def readlines(self):
         return self.my_text.splitlines()

then just call it like:

somefake = FileSpoof("This is a bunch\nOf Text!")
print somefake.readlines()

That said the other answer is probably more correct.
