Design test cases to verify a computer program : Testing Classes

The video tutorial covers testing a printer class in Python. It begins with setting up a test case and writing the first test to check the printer's capacity and speed. The instructor explains the importance of using a float for pages per second and discusses different ways to validate test results. The video then delves into the setup method, emphasizing the need for a new printer object for each test to avoid state issues. It concludes with a discussion on setup class and teardown methods, advising against sharing objects across tests to maintain test integrity.

What is the purpose of the setup method in testing?

Why is it recommended not to share the printer object across tests?
