Which statement is true regarding confirmation testing and regression testing?

1. A. Confirmation testing confirms the quality of the test being run while regression testing ensures that the software still works after a change has been made.
2. B. Confirmation testing is an optional activity whilst regression testing is not negotiable.
3. C. Confirmation testing aims to verify that a defect has been resolved and regressiontesting ensuring that existing functionality still works after a change.
4. D. Testers' involvement is essential whilst running retesting and regression testing.
5. E. TESTER Involvement is essential whilst running retesting and regression testing.

Correct Answer: C
Confirmation testing, also known as retesting, is conducted to verify that specific defects have been fixed. Regression testing, on the other hand, is performed to ensure that recent changes have not adversely affected existing features of the software. Both types of testing are crucial for maintaining the integrity and quality of the software after modifications.

Which of the following statements about statement coverage is TRUE?

1. A. Achieving 90% statement coverage ensures that 90% branch coverage is achieved.
2. B. Achieving 100% statement coverage ensures that no variable within the code has been used without being initialised.
3. C. Achieving 100% statement coverage ensures that 100% branch coverage is achieved
4. D. Achieving 80% statement coverage ensures that 80% of all executable statements within the code have been exercised.

Correct Answer: D
Statement coverage measures the percentage of executable statements that have been exercised by a test suite. Achieving 80% statement coverage means that 80% of the executable code lines have been tested. This metric helps in understanding how much of the code has been covered during testing. However, it does not guarantee branch coverage, variable initialization, or detection of all possible defects. The ISTQB CTFL Syllabus v4.0 explains statement coverage as a measure of the extent to which the code has been tested, without implying other types of coverage or testing goals.

Which of the following statements about white-box testing is FALSE?

1. A. Static testing can benefit from using code-related white-box test techniques during code reviews.
2. B. White-box testing allows suggesting test cases for increasing coverage levels which are based on objective measures
3. C. Achieving full code coverage for a component or a system ensures that it has been fully tested
4. D. Black-box testing can benefit from using code-related white-box test techniques to increase confidence in the code.

Correct Answer: C
Achieving full code coverage does not guarantee that the component or system is fully tested or free of defects. Code coverage metrics indicate the extent to which the source code has been tested, but they do not account for the quality of the tests or whether all possible scenarios have been considered. Other types of testing, including functional, performance, and security testing, are necessary to ensure comprehensive testing. The ISTQB CTFL Syllabus v4.0 highlights that while high code coverage is beneficial, it does not equate to complete testing.

A possible risk of introducing test automation is:

1. A. the tool may not be fit-for-purpose.
2. B. the tool may create additional development dependencies.
3. C. the tool may not be compatible with the development platform.
4. D. the tool will be owned and maintained by developers and replace testers.

Correct Answer: A
One possible risk of introducing test automation is that the selected tool may not be fit-for- purpose. This means that the tool might not meet the specific needs and requirements of the project, leading to inefficiencies and possibly failing to provide the expected benefits. It is crucial to evaluate and select the appropriate tool based on the project's context and objectives. The ISTQB CTFL syllabus highlights the importance of careful tool evaluation and selection to ensure it aligns with the testing goals and the development environment.
