Important ISTQB CTFL-Foundation Exam Questions

Answer: B

Explanation:

Regression testing serves to demonstrate that unchanged areas of the software have not been unintentionally affected by changes. The ISTQB CTFL syllabus v4.0 states that while regression testing can be carried out at various stages of the lifecycle and is often automated, its primary purpose is to ensure that existing functionality remains unaffected after changes.

Answer: D

Explanation:

All the options listed (Planning and control, Test closure activities, Analysis and design) are indeed part of the fundamental test process. The fundamental test process includes activities such as planning and control, analysis and design, implementation and execution, evaluating exit criteria and reporting, and test closure activities. Thus, the correct answer is 'None,' as all options are fundamental parts of the test process.

Answer: D

Explanation:

The other answers are incorrect because:

(ii) Walkthroughs do not require code and static analysis does require code.

(iv) Static techniques do not execute the code and therefore can be run before and after the code is ready for execution.

Answer: A

Explanation:

The concept of introducing a small change to the program and having the effects of that change show up in some test is known as 'introducing mutations.' This is part of mutation testing, where small changes (mutations) are made to the code to see if the existing test cases can detect the errors introduced by these changes. The goal is to evaluate the effectiveness of the test cases in identifying defects. Reference: ISTQB CTFL Syllabus V4.0, Section 4.3.4.

Answer: A

Explanation:

The fundamental test process consists of several sequential steps: planning and control, analysis, design, implementation, execution, evaluation of exit criteria and reporting, and test closure. This comprehensive process ensures that testing is methodical and covers all necessary aspects from preparation to conclusion.
