BCS ISTQB Certified Tester Foundation Level CTFL 4.0 認定 CTFL4 試験問題 (Q172-Q177):

質問 # 172
Which of the following is a factor that contributes to a successful review?

A. All participants in the review are aware they will be evaluated based on the defects they will find
B. The author of the work product to be reviewed leads the review meeting.
C. All participants in the review are trained to deal with the review type and its objectives.
D. Review metrics must be collected to improve the review process

正解：C

解説：
A successful review process involves all participants being trained in the review type and understanding its objectives. This ensures that everyone can contribute effectively and understand what is expected from the review. Proper training helps to identify defects accurately and facilitates constructive feedback, leading to a more efficient and effective review process. Hence, statement C is correct according to the ISTQB CTFL syllabus.

質問 # 173
Which of the following statements about the shift-left approach is FALSE?

A. The shift-left approach can involve security vulnerabilities
B. The shift-left approach in testing is compatible with DevOps practices.
C. The shift-left approach can only be implemented with test automation
D. The shift-left approach can be supported by static analysis tools.

正解：C

解説：
In a formal review process, the recorder's role is typically responsible for documenting the findings of the review team, including action items, decisions, and recommendations. This ensures that there is an accurate record of what was discussed and agreed upon, facilitating follow-up and continuous improvement. Therefore, statement C is correct as per the ISTQB CTFL syllabus.

質問 # 174
The tests at the bottom layer of the test pyramid:

A. are defined as 'Ul Tests' or 'End-To-End tests' in the different models of the pyramid
B. are unscripted tests produced by experience-based test techniques
C. run faster than the tests at the top layer of the pyramid
D. cover larger pieces of functionalities than the tests at the top layer of the pyramid

正解：C

解説：
The tests at the bottom layer of the test pyramid run faster than the tests at the top layer of the pyramid because they are more focused, isolated, and atomic. They usually test individual units or components of the software system, such as classes, methods, or functions. They are also easier to maintain and execute, as they have fewer dependencies and interactions with other parts of the system. The tests at the top layer of the test pyramid, on the other hand, are slower because they cover larger pieces of functionalities, such as user interfaces, workflows, or end-to-end scenarios. They also have more dependencies and interactions with other systems, such as databases, networks, or external services. They are more complex and costly to maintain and execute, as they require more setup and teardown procedures, test data, and test environments.

質問 # 175
Which of the following coverage criteria results in the highest coverage for state transition based test cases?

A. Covering only start and end states
B. Can't be determined
C. Covering all states at least once
D. Covering all transitions at least once

正解：D

解説：
Covering all transitions at least once is the highest coverage criterion for state transition based test cases, because it ensures that every possible change of state is tested at least once. This means that all the events that trigger the transitions, as well as the actions and outputs that result from the transitions, are verified. Covering all transitions at least once also implies covering all states at least once, but not vice versa. Therefore, option D is not the highest coverage criterion. Option C is the lowest coverage criterion, because it only tests the initial and final states of the system or component, without checking the intermediate states or transitions. Option A is incorrect, because the coverage criteria for state transition based test cases can be determined and compared based on the number of transitions and states covered. Reference = CTFL 4.0 Syllabus, Section 4.2.3, page 49-50.

質問 # 176
A company runs a pilot project for evaluation of a test automation tool. Which of the following is NOT a valid object of this pilot project?

A. Check haw the tool fits to the existing test processes
B. Decide upon standards for tool implementation
C. Get familiar with the functionality and options of the tool
D. Train all testers on using the tool

正解：D

解説：
* A pilot project is a small-scale experiment or trial that is conducted to evaluate the feasibility, effectiveness, and suitability of a test automation tool before implementing it on a larger scale1.
* The objectives of a pilot project may vary depending on the context and scope of the test automation initiative, but some common ones are2:
* To get familiar with the functionality and options of the tool
* To check how the tool fits to the existing test processes and environment
* To assess the benefits and challenges of using the tool
* To decide upon standards and guidelines for tool implementation and usage
* To estimate the costs and resources required for tool deployment and maintenance
* Therefore, option C is not a valid objective of a pilot project, as it is not necessary to train all testers on using the tool at this stage. Training all testers on using the tool would be more appropriate after the tool has been selected and approved for full-scale implementation, and after the standards and guidelines have been established. Training all testers on using the tool during the pilot project would be inefficient, costly, and premature, as the tool may not be suitable or effective for the intended purpose, or may be replaced by another tool later.
