iSQI CTFL-AT Dumps Questions Answers

Independence in testing is the degree of separation between the person who tests something and the person who developed it. Independence can help to reduce bias, increase objectivity, and provide different viewpoints. However, independence also has some drawbacks, such as increased communication overhead, reduced collaboration, and delayed feedback. In agile projects, testers are usually embedded in the agile teams to perform many of the testing tasks, such as unit testing, integration testing, acceptance testing, etc. This provides a high level of collaboration and fast feedback, but also reduces the independence of the testers. Testers from an independent test team who do not get involved with the agile team, but are assigned to do System Testing once all sprints are completed, would provide the most independence for testers working with agile teams. However, this would also introduce many disadvantages, such as lack of alignment with the agile principles, loss of context and domain knowledge, delayed defect detection and resolution, and increased risk of missing customer expectations. References: ISTQB® Foundation Level Agile Tester Syllabus, Section 1.1.2, page 8; ASTQB Agile Tester Certification Resources, Section 1.1.2, page 8.

Comprehensive and Detailed Explanation From Exact Extract:

FromCTFL-AT Syllabus v4.0, Section 3.1Testing Techniques and Agile, it states:

"Decision table testing is useful when the outcome depends on combinations of inputs or rules."

In this case,different reimbursement percentagesare determined based ontypes of visits and subtypes, makingOption A (Decision Table Testing)the ideal technique.

Option Bfocuses onsingle input ranges, less suitable here.

Option Csuits end-to-end scenarios but not logic-driven calculations.

Option Dapplies tostate-based systems, which this is not.

 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 input domain of the system, but rather on the conditions, transitions, or scenarios that are not directly related to the user story. References:
