Free CTFL-AT: Certified Tester Foundation Level Agile Tester Exam Questions and Answers
Certified Tester Foundation Level Agile Tester is part of the Certified Tester scheme from the International Software Testing Qualifications Board. ISTQB does not run the exams itself. It owns the syllabus and accredits national Member Boards and Exam Providers, who set the fee, the language and the sitting — which is why no single price is published anywhere. The ladder is real and enforced: Foundation first, then Advanced or a Specialist module, then Expert, with 65% the pass mark throughout and Foundation at 26 marks out of 40. One thing catches people out: Foundation, Specialist and Advanced certificates never expire, while Expert level lapses after seven years.

Question #1
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?
Correct answer: C
Explanation
Equivalence partitioning is a black-box test design technique that divides the input domain of a system into classes of data from which test cases can be derived. The idea is that if a system works correctly for a representative value from an equivalence class, it will work correctly for all values from that class, and vice versa. Equivalence partitioning reduces the number of test cases by eliminating redundant ones. For the given user story, equivalence partitioning is the most suitable technique because it can test the different outcomes of the annual car tax calculation based on the power of the vehicle, which is the main input for the system. By testing one value from each partition, the tester can verify the functionality of the system and detect any errors in the calculation logic. The other techniques are not as suitable because they do not focus on the inputdomain of the system, but rather on the conditions, transitions, or scenarios that are not directly related to the user story.
