Which of the following statements BEST describes one of the seven key principles of software testing?
One of the seven key principles of software testing is that exhaustive testing is impossible. This principle highlights the impracticality of testing all possible input and output combinations due to the vast number of permutations. Instead, risk-based and prioritized testing approaches should be used to focus on the most critical areas. This principle is fundamental in the ISTQB CTFL Syllabus, emphasizing the importance of efficient test strategy over attempting exhaustive testing.
When an organization considers the use of testing tools, they should:
When considering the use of testing tools, it is essential to first perform an analysis of the current test process. This analysis helps identify areas where tool support can provide the most benefit. Introducing tools without this assessment might lead to inefficiencies or the selection of inappropriate tools. A thorough evaluation ensures that the tools will effectively support and enhance the existing test process.
Which of the following is a structure-based (white-box) technique?
Statement testing is a structure-based (white-box) technique. This technique involves testing the internal structure of the application, focusing on the execution of the statements within the code. The goal is to ensure that every statement in the code has been executed at least once during the testing process. Other options like decision table testing, state transition testing, and boundary value analysis are black-box techniques, which do not require knowledge of the internal code structure. Reference: ISTQB CTFL Syllabus V4.0, Section 4.3.1.
Which of the following are examples of iterative development models?
(i) V-model
(ii) Rapid Application Development model
(iii) Waterfall model
(iv) Agile development model
Iterative development models include the Rapid Application Development (RAD) model and Agile development model. The ISTQB CTFL syllabus v4.0 explains that these models involve repeated cycles of development activities, allowing for incremental improvements and adjustments based on feedback.
System testing is:
System testing is a level of software testing where a complete and integrated software is tested. The purpose of this test is to evaluate the system's compliance with the specified requirements. System testing is conducted on the entire system to verify that it behaves as expected and meets the functional and non-functional requirements defined in the scope of the project.
