質問 # 12
Which of the following would typically be identified using static analysis by tools? [K1]
- A. Memory leakage
- B. Spelling mistake on an error message
- C. A variable set to the wrong value
- D. A potential infinite loop
正解：D
解説：
Static analysis tools are designed to examine the code without executing it. They are particularly effective at identifying structural issues in the code, such as potential infinite loops (B), which can occur due to incorrect logic that would cause the code to execute indefinitely. These tools analyze the code's structure and logic flow to find such issues early in the development process, helping to improve the code's quality before it is run.

質問 # 21
Which of the following test design techniques is not a black box technique?
- A. Equivalence partitioning
- B. Statement coverage
- C. State transition testing
- D. Boundary value analysis
正解：B
質問 # 22
Functional and structural tests are alternative test types that may be used separately or together at which test level? [K1]
- A. At all levels from integration testing to acceptance testing
- B. At the component test level only
- C. At all test levels
- D. At integration testing and system testing levels only
正解：C
解説：
Functional and structural tests are types of testing techniques that can be applied at various levels of testing.
According to the ISTQB CTFL syllabus, functional and structural tests are not restricted to any specific test level but are applicable across all levels of testing. This includes component, integration, system, and acceptance testing. The use of both types of tests helps ensure comprehensive testing coverage, addressing both the functional requirements and the internal structure of the software product.
質問 # 23
What can a risk-based approach to testing provide?
- A. Only that test execution is effective at reducing risk.
- B. An estimation of the total cost of testing.
- C. The types of test techniques to be employed.
- D. The total tests needed to provide 100 per cent coverage.
正解：C
解説：
A risk-based approach to testing provides information on the types of test techniques to be employed. This approach prioritizes the testing of features and functions based on their risk of failure and their impact on the organization. By identifying the areas of highest risk, test managers can allocate resources and select test techniques that are most likely to uncover defects in these critical areas. This approach ensures that testing efforts are focused where they are most needed. Reference: ISTQB CTFL Syllabus V4.0, Section 5.2
質問 # 24
What if the project isn't big enough to justify extensive testing..?
- A. Use automation tool for testing
- B. None of the above
- C. Both a and b
- D. Use risk based analysis to find out which areas need to be tested
正解：D
解説：
If the project isn't big enough to justify extensive testing, the best approach is to use risk-based analysis. This method prioritizes testing efforts based on the risk of failure and the impact of defects. It helps in identifying critical areas that need more focus, thus optimizing the testing process by concentrating on high-risk components and functionalities.
質問 # 25

Maintenance testing is:
- A. testing to maintain business advantage
- B. testing a released system that has been changed
- C. updating tests when the software has changed
- D. testing by users to ensure that the system meets a business need
正解：B
解説：
Maintenance testing refers to the testing that is conducted on a software system that has been changed, either through corrections, enhancements, or other modifications. Its main purpose is to ensure that the changes have been implemented correctly and that the system as a whole continues to function as intended. This type of testing is crucial after a system has been released and needs to be updated or fixed. Maintenance testing ensures that the new changes do not adversely affect the existing functionality of the system.REREE33
