Consider an online application that allows registered users to pay the annual car tax based on the vehicle's engine power in kW. Given the following user story:

''As a customer I need the online application to calculate the annual car tax amount that I need to pay for my car":

- If the power of the vehicle is less than 20 kW, then the annual car tax is free

- If the power of the vehicle is more or equal than 20 kW but less or equal than 150 kW, then the annual car tax is 250 Euros

- If the power of the vehicle is more than 150 kW, then the annual car tax is 750 Euros"

What is the MOST suitable use of a black-box test design technique for this user story?

SELECT ONE OPTION

AState transition testing. Test the transitions between the following states: logging In. inserting the power of the vehicle, making payment, logging out

BUse case testing.
Test the following use case (Actor=registered user):
Pre-condition=registered user logged in

I just hope the online application has a user-friendly interface. Imagine having to input the power of your car in kilowatts - that could get confusing for some people!

Haha, I wonder if there's a special 'Lamborghini tax' for cars with over 1000 kW of power. That would really put a dent in your wallet!

I think the most suitable test design technique would be Equivalence Partitioning. It allows us to test the different ranges of vehicle power and ensure the correct annual car tax is calculated for each one.
