Use case testing is a technique that focuses on testing the system's behavior based on user scenarios or interactions. It aims to validate that the system functions correctly in real-world situations. Therefore, it is most likely to uncover defects in the process flows during real-world use of the system (i) as well as integration defects caused by the interaction and interference of different components (iii). The other options (ii, iv) are not directly related to the main objective of use case testing.Rate this question:

Which of the following is MOST important in the selection of a test approach?
- A.
Availability of tools to support the proposed techniques.
- B.
The budget allowed for training in proposed techniques.
- C.
Available skills and experience in the proposed techniques.
- D.
The willingness of the test team to learn new techniques.
Correct Answer
C. Available skills and experience in the proposed techniques.Explanation
The most important factor in the selection of a test approach is the available skills and experience in the proposed techniques. This is because the success of a test approach heavily relies on the competence and knowledge of the test team in utilizing the techniques effectively. Without the necessary skills and experience, the team may struggle to properly implement the approach, leading to ineffective testing and potential issues in the software being tested. The availability of tools, budget for training, and willingness to learn new techniques are also important, but they are secondary factors that can be addressed and improved upon if the team has the required skills and experience.Rate this question:

Which of the following is a benefit of test independence?
- A.
It does not require familiarity with the code.
- B.
It is cheaper than using developers to test their own code.
- C.
It avoids author bias in defining effective tests.
- D.
Testers are better at finding defects than developers.
Correct Answer
C. It avoids author bias in defining effective tests.Explanation
Test independence is a benefit because it avoids author bias in defining effective tests. When the author of the code is responsible for testing it, they may unintentionally overlook certain scenarios or defects. By having a separate tester who is not involved in the development process, there is a higher chance of identifying potential issues and ensuring that the tests are comprehensive and effective. This helps in improving the overall quality of the software being tested.Rate this question:

The above diagram represents the following paths through the code.A. vwyB. vwzC. vxyD. vxzWhat is the MINIMUM combination of paths required to provide full statement coverage?
- A.
A
- B.
ABD
- C.
ABCD
- D.
ACD
Correct Answer
A. AExplanation
The minimum combination of paths required to provide full statement coverage is A. This means that by following path A alone, all the statements in the code will be executed at least once. Following any additional paths, such as B, C, or D, would not provide any additional coverage as they would duplicate the execution of statements already covered by path A. Therefore, path A is sufficient to achieve full statement coverage.Rate this question:

Which of the following is MOST characteristic of specification based (black-box) techniques?
- A.
Test cases can be easily automated.
- B.
Test cases are independent of each other.
- C.
Test cases are derived systematically from models of the system .
- D.
Test cases are derived systematically from the delivered code.
Correct Answer
C. Test cases are derived systematically from models of the system .Explanation
Specification-based (black-box) techniques involve deriving test cases systematically from models of the system. This means that the test cases are based on the requirements or specifications of the system, rather than the internal structure or code. This approach allows for a more objective and systematic testing process, as the focus is on ensuring that the system meets the specified requirements. Additionally, this characteristic also implies that the test cases can be easily automated, as they are derived from models that can be used to generate automated tests.Rate this question:
