問題 #136
Which of the following statements about TDD, BDD and ATDD is true?
答案：A
解題說明：
Test-Driven Development (TDD) includes refactoring as a key practice. After writing tests and the code to satisfy those tests, refactoring is performed to improve the code and test quality without changing the functionality. This continuous process helps maintain clean, efficient, and manageable code.

問題 #137
Scenario 2 "Big Drop":
A company"The Big Drop"providesbulk discounts and frequent customer discountsas follows:
How manypossible decision rulescan be extracted from this table?
答案：D
解題說明：
Decision rules define possiblecombinations of conditions and outcomes.
For this scenario:
* Bulk discount has 3 categories(0%, 5%, 10%)
* Frequent customer discount has 2 categories(Yes = +5%, No = 0%)
The total number of decision rules is:
3 bulk discount options × 2 frequent customer options = 6 rules.
Thus, the correct answer is6 decision rules (B).

問題 #138
The four test levels used in ISTQB syllabus are:
1. Component (unit) testing
2. Integration testing
3. System testing
4. Acceptance testing
An organization wants to do away with integration testing but otherwise follow V-model. Which of the following statements is correct?
答案：C
解題說明：
The V-model is a software development life cycle model that defines four test levels that correspond to four development phases: component (unit) testing with component design, integration testing with architectural design, system testing with system requirements, and acceptance testing with user requirements. The V-model emphasizes the importance of verifying and validating each phase of development with a corresponding level of testing, and ensuring that the test objectives, test basis, and test artifacts are aligned and consistent across the test levels. Therefore, an organization that wants to follow the V-model cannot do away with integration testing, as it would break the symmetry and completeness of the V-model, and compromise the quality and reliability of the software or system under test. Integration testing is a test level that aims to test the interactions and interfaces between components or subsystems, and todetect any defects or inconsistencies that may arise from the integration of different parts of the software or system. Integration testing is essential for ensuring the functionality, performance, and compatibility of the software or system as a whole, and for identifying and resolving any integration issues early in the development process. Skipping integration testing would increase the risk of finding serious defects later in the test process, or worse, in the production environment, which would be more costly and difficult to fix, and could damage the reputation and credibility of the organization. Therefore, the correct answer is D.
The other options are incorrect because:
* A. It is not allowed as organizations can decide on the test levels to do depending on the context of the system under test. While it is true that the choice and scope of test levels may vary depending on the context of the system under test, such as the size, complexity, criticality, and risk level of the system, the organization cannot simply ignore or skip a test level that is defined and required by the chosen software development life cycle model. The organization must follow the principles and guidelines of the software development life cycle model, and ensure that the test levels are consistent and coherent with the development phases. If the organization wants to have more flexibility and adaptability in choosing the test levels, it should consider using a different software development life cycle model, such as an agile or iterative model, that allows for more dynamic and incremental testing approaches.
* B. It is not allowed because integration testing is not an important test level and can be dispensed with.
This statement is false and misleading, as integration testing is a very important test level that cannot be dispensed with. Integration testing is vital for testing the interactions and interfaces between components or subsystems, and for ensuring the functionality, performance, and compatibility of the software or system as a whole. Integration testing can reveal defects or inconsistencies that may not be detected by component (unit) testing alone, such as interface errors, data flow errors, integration logic errors, or performance degradation. Integration testing can also help to verify and validate the architectural design and the integration strategy of the software or system, and to ensure that the software or system meets the specified and expected quality attributes, such as reliability, usability, security, and maintainability. Integration testing can also provide feedback and confidence to the developers and stakeholders about the progress and quality of the software or system development.
Therefore, integration testing is a crucial and indispensable test level that should not be skipped or omitted.
* C. It is not allowed because integration testing is a very important test level and ignoring it means definite poor product quality. This statement is partially true, as integration testing is a very important test level that should not be ignored, and skipping it could result in poor product quality. However, this statement is too strong and absolute, as it implies that integration testing is the only factor that determines the product quality, and that ignoring it would guarantee a poor product quality. This is not necessarily the case, as there may be other factors that affect the product quality, such as the quality of the requirements, design, code, and other test levels, the effectivenessand efficiency of the test techniques and tools, the competence and experience of the developers and testers, the availability and adequacy of the resources and environment, the management and communication of the project, and the expectations and satisfaction of the customers and users. Therefore, while integration testing is a very important test level that should not be skipped, it is not the only test level that matters, and skipping it does not necessarily mean definite poor product quality, but rather a higher risk and likelihood of poor product quality.

問題 #139
Which of the following is NOT an example of a test-first approach to development?
答案：B
解題說明：
Test Coverage-Driven Development focuses on measuring coverage after tests are created and executed, not on writing tests before development, so it is not a test-first approach.
