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.

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?

Answers
D.
Experienced testers, when applying error guessing technique, can anticipate where errors, defects and failures have occurred and target their tests at those issues
Suggested answer: D

Explanation:

This answer is correct because error guessing is a test design technique where the experience and intuition of the tester are used to anticipate where errors, defects and failures have occurred or are likely to occur, and to design test cases to expose them. Error guessing can be based on factors such as the complexity of the system or component, the known or suspected weaknesses of the system or component, the previous history of defects, or the common types of errors in the domain or technology. Error guessing can be used as a complementary technique to other more systematic or formal techniques, or when there is insufficient information or time to apply them.Reference: ISTQB Glossary of Testing Terms v4.0, ISTQB Foundation Level Syllabus v4.0, Section 2.3.2.5
