How can the test be adjusted if the sum3 method is changed to multiply instead of add?

When the sum3 method is modified to perform multiplication instead of addition, the expected outcome of the method's output changes accordingly. In this scenario, the assertion in the test must be adjusted to reflect the new purpose of the function.

By changing the assertion to verify the expected multiplication result, the test will ensure that it correctly evaluates the functionality of the newly implemented method. For example, if the method was initially tested with inputs that added up to a specific number, after the function's modification to multiplication, those same inputs will produce a different result when multiplied. Therefore, the new assertion needs to account for this change, validating that the method accurately multiplies the inputs and returns the correct product.

This focus on adjusting the assertion is crucial for maintaining the integrity of the test and ensuring that it reliably checks the correctness of the method's functionality following the change in its operational logic.
