[All ISTQB Certified Tester - Agile Tester Questions]

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?

ADecision table testing. Test the following conditions:
Conditions=registered user logged in; inserted power of the vehicle=20kW;
Action=Car tax paid

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

CEquivalence partitioning. Test the annual car tax value for the following partitions:
[power of the vehicle<20 kW ; 20 kW power of the vehicles150 kW; power of the vehicle>150 kW]

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