Design test cases to verify a computer program : Testing the Multiplication Function

The video tutorial covers the implementation of a new function called 'multiply' that takes multiple arguments, either integers or floats. It explains the function's logic, error handling, and the importance of writing tests to ensure correct behavior. The tutorial discusses boundary value analysis, equivalence partitioning, and special cases like zero and negative values. It also highlights the role of type hinting in preventing errors and concludes with suggestions for further learning.

What is the purpose of using the star operator in the 'multiply' function?

• To ensure all arguments are integers

• To limit the number of arguments

• To allow passing a list of arguments

• To enable passing any number of individual arguments

Why is it important to write tests for the 'multiply' function?

• To reduce the number of lines of code

• To ensure the function behaves as expected

• To make the code run faster

• To avoid using type hinting

What happens if no arguments are passed to the 'multiply' function?

• The function multiplies by a default value

• The function returns zero

• The function raises a ValueError

• The function returns one

What is the expected result when multiplying a single value using the 'multiply' function?

• The result is always one

• The result is the same as the input value

• The result is always zero

• The result is doubled

How does the 'multiply' function handle zero in its inputs?

• It returns zero as the result

• It ignores zero

• It returns one as the result

• It raises an error

What is the role of type hinting in the 'multiply' function?

• To make the function run faster

• To allow any data type as input

• To automatically test the function

• To ensure only integers and floats are accepted

Which library is mentioned as a way to reduce test duplication?

• NumPy

• Matplotlib

• Pandas

• Hypothesis
