Design test cases to verify a computer program : Testing for Errors

The video tutorial teaches how to test for errors in functions, specifically focusing on the divide function. It explains how to raise a ValueError when a divisor is zero and how to implement a test to check for this error using 'self.assertRaises'. The tutorial also discusses alternative methods for error testing, such as using a lambda function, and concludes with a recommendation to use context managers for clarity.

Why is using a context manager recommended for checking errors?

Explain the difference between passing a callable and calling a function directly in error testing.
