The following diagram displays the logical dependencies between requirements and the individual requirement priorities. For example, 'R2->R3' means that R3 is dependent on R2.

Which one of the following options best describes the test execution sequence using both requirement dependency and priority
A financial institution is to implement a system that calculates the interest rates paid on investment accounts based on the sum invested. You are responsible for testing the system and decide to use equivalence partitioning and boundary value analysis to design test cases. The requirements describe the following expectations: Investment range | Interest rate R500 to RIO 000 10% RIO 001 to R50 000 11% R50 001 to RlOOOOO 12% RIOOOOl to R500 000 | 13% What is the minimum number of test cases required to cover all valid equivalence partitions for calculating the interest?
Which of the following BEST matches the descriptions with the different categories of test techniques? 1. Test cases are based on the test basis which may include the requirements, use cases and user stories 2. Test cases are based on the test basis which may include the software architecture or code 3. Test cases can show deviations from the requirements 4. These test techniques are applicable to both functional and non-functional testing 5. Tests are based on knowledge of developers, users and other stakeholders Black - Black-box test techniques White * White-box test techniques Experience - Experience-based test techniques

Consider a review for a high-level architectural document written by a software architect. The architect does most of the review preparation work, including distributing the document to reviewers before the review meeting. However, reviewers are not required to analyze the document in advance, and during the review meeting the software architect explains the document step by step. The only goal of this review is to establish a common understanding of the software architecture that will be used in a software development project. Which of the following review types does this review refer to?

Which or the following is a valid collection of equivalence classes for the following problem: An integer field shall contain values from and including 1 to and including 15.

A.
Less than 0.1 through 14. 15 and more
Answers
A.
Less than 0.1 through 14. 15 and more
B.
Less than 1.1 through 14. more than 15
Answers
B.
Less than 1.1 through 14. more than 15
C.
negative numbers. 1 through 15. above 15
Answers
C.
negative numbers. 1 through 15. above 15
D.
Less than 1.1 through 15. more than 15
Answers
D.
Less than 1.1 through 15. more than 15
Suggested answer: D

Explanation:

Equivalence partitioning is a black-box test design technique where inputs to the software or system are divided into groups that are expected to exhibit similar behavior. For an integer field that should accept values from 1 to 15, the valid equivalence class is 1 through 15. The invalid equivalence classes are numbers less than 1 and numbers more than 15. Therefore, option D, 'Less than 1, 1 through 15, more than 15,' correctly identifies the valid equivalence class along with the two invalid classes, covering all possible input scenarios for the field. Options A, B, and C either do not accurately capture the valid range or incorrectly specify the range boundaries.
