Mock Objects

Exercise 1: Using a Mock Object

The function word_report.get_top_words() requires an instance of the class TextBody. You need to test the function, excluding the possibility that the TextBody class is buggy. To do so, you need to replace the class by a Mock Object, a simple placeholder.

Your task is to write a test for the function word_counter.get_top_words() that does not use the class TextBody.
