ISTQB Updated ISTQB-CTFL Exam Questions and Answers by winifred

Comprehensive and Detailed In-Depth Explanation:Acceptance criteria8states thatthe system should charge the user on the first business day of the following month. However, thetest cycle only verified monthly payments for over a year, without confirming whether payments were processedspecifically on the first business day.

(B) is incorrectbecause the test validatedmonthly and annual payment options.

(C) is incorrectbecause not all criteria were fully validated.

(D) is incorrectbecause OTP verification (6) was tested as part of registration.

Ensuringtimely execution of payments(Criteria 8) requires additional validation.

This answer is correct because identifying potential anomalies in the work product under review is one of the tasks the Author is responsible for, as part of a typical formal review. The Author is the person who creates the work product to be reviewed, such as a requirement specification, a design document, or a test case. The Author’s tasks include preparing the work product for the review, identifying potential anomalies in the work product, and fixing the anomalies found in the work product after the review. References: ISTQB Glossary of Testing Terms v4.0, ISTQB Foundation Level Syllabus v4.0, Section 2.4.2.1

Component testing (also known as unit testing or module testing) is a level of testing that focuses on verifying the functionality and quality of individual software components (such as modules, classes, functions, methods, etc.). Component testing mainly tests interfaces and interaction between components, as well as internal logic and data structures of the components. Component testing may be applied using a test-first approach (such as test-driven development or behavior-driven development), where tests are written before the code is implemented. Component testing does not identify defects in modules and classes, as this is a result of component testing, not an objective. Simulators and stubs may be required for component testing, as they can simulate or replace missing or incomplete components or external systems that are needed for testing.

The key principles of software testing include: i. Testing shows the presence of defects, not their absence. iv. Defects cluster together. v. Testing is context dependent. vi. Beware of the pesticide paradox. vii. Absence of errors is a fallacy. These principles highlight the importance of recognizing the limitations and context of testing, as well as the potential for repeated tests to become less effective​​.
