Question 1: Which of the following is NOT a verification technique?
Correct Answer: c. Integration testing
Explanation:
Software verification refers to the process of evaluating work-products of a development phase to ensure that they meet the specified requirements and are built correctly. Verification focuses on reviewing documents, design, code, and programs to confirm correctness, consistency, and completeness before they are executed.
Common verification techniques include:
- Inspection: A formal, systematic examination of software artifacts like design documents or code to detect defects early.
- Walkthrough: A peer-review technique where the author leads team members through the product and feedback is gathered.
- Technical Reviews: Structured group meetings to examine software products and improve quality.
Integration Testing, on the other hand, is a validation technique, not a verification technique. Validation involves executing the software to ensure it behaves as expected. Integration testing specifically focuses on checking data flow and interactions between integrated modules of the software. It is part of the dynamic testing phase and occurs after verification activities.
So, while inspection and walkthroughs are static methods that don’t involve executing code (verification), integration testing is a dynamic process (validation) that checks if the code functions correctly when combined.
Thus, the correct answer is c. Integration testing because it is not a verification technique.
Question 2: Which is not a feature of OOP in general definitions?
Correct Answer: d) Duplicate/Redundant data
Explanation:
Object-Oriented Programming (OOP) is a paradigm centered around objects and classes, promoting real-world modeling in software design. The core features of OOP are:
- Encapsulation: Hiding internal object details and exposing only necessary parts.
- Inheritance: Allowing one class to inherit properties and behavior from another.
- Polymorphism: Enabling a single interface to support different underlying data types.
- Abstraction: Focusing on essential characteristics and hiding complex details.
Additional general benefits include:
- Code Reusability: OOP supports using existing code through inheritance and object instantiation.
- Modularity: Code is divided into discrete objects or modules, making it easier to manage and debug.
- Efficient Code: By reducing redundancy and reusing code, OOP can help create efficient and maintainable codebases.
On the contrary, duplicate or redundant data is not a feature of OOP. In fact, one of the key goals of OOP is to avoid redundancy through reuse and abstraction. Redundant data leads to inconsistencies, increased memory usage, and difficulties in maintenance, which OOP techniques aim to eliminate.
Therefore, the correct answer is d) Duplicate/Redundant data, as it contradicts the foundational principles of OOP.
