Validation is concerned with ______ testing, while verification deals with ______ testing.
- White-box, Black-box
- Black-box, White-box
- Functional, Structural
- Unit, Integration
Validation primarily focuses on black-box testing, where the internal structure of the software is not considered, but its functionality is validated against user requirements. Verification is associated with white-box testing, where the internal code structure is examined for correctness and adherence to design.
Quality Assurance in Agile involves regular _______ to discuss any issues or changes needed in the ongoing project.
- Documentation reviews
- Risk assessments
- Status meetings
- Testing phases
Quality Assurance in Agile involves regular status meetings to discuss any issues or changes needed in the ongoing project. These meetings help ensure that the project aligns with its goals and that quality is maintained.
A _____ architecture style has a single codebase and is often easier to deploy.
- Monolithic
- Microservices
- Client-Server
- Peer-to-Peer
The Monolithic architecture style has a single codebase, and it is often easier to deploy as the entire application is packaged as a single unit. This simplicity can make deployment and maintenance more straightforward.
In a scenario where a software system is expected to experience frequent changes due to market dynamics, discuss how software evolution models can be strategically applied to manage these changes effectively.
- Utilize iterative models
- Implement a traditional waterfall model
- Employ agile methodologies
- Choose a fixed model
In a dynamic market environment, where frequent changes are expected, it is essential to apply software evolution models that are adaptable. Iterative models, such as Agile methodologies, allow for incremental and flexible development, making them a strategic choice to manage changes effectively. They enable continuous adaptation to evolving requirements and market dynamics.
Which principle suggests that derived classes must be substitutable for their base classes?
- Encapsulation
- Abstraction
- Inheritance
- Polymorphism
The principle suggesting that derived classes must be substitutable for their base classes is "Polymorphism." It allows objects of derived classes to be used where objects of the base class are expected, enabling flexibility and extensibility in software design.
A ______ audit is performed to ensure that all contractual agreements have been fulfilled and the product meets the specified requirements.
- Technical
- Quality
- Compliance
- Code
A compliance audit is performed to ensure that all contractual agreements, legal requirements, and specified standards have been fulfilled. In the context of software engineering, this type of audit is crucial to confirm that the product adheres to all requirements and agreements.
The main objective of ______ maintenance is to foresee and solve problems and issues before they occur.
- Corrective
- Adaptive
- Preventive
- Perfective
Preventive maintenance focuses on anticipating and preventing issues before they occur. It involves tasks such as code reviews, proactive bug-fixing, and performance optimization to maintain the system's reliability.
When is regression testing typically performed within the software development process?
- At the beginning of the development phase
- After the software has been released to users
- During the initial testing phase
- After code changes are made, and before a new release or update
Regression testing is typically performed after code changes are made and before a new release or update of the software. It ensures that existing functionality remains intact after modifications.
If a software development team is adhering to Test-Driven Development (TDD) principles, how might the process of Unit Testing be integrated into their daily work?
- Unit tests are conducted only after the entire system is built
- Unit tests are written before the code is implemented
- Unit tests are conducted by a separate QA team
- Unit tests are skipped in TDD
In Test-Driven Development (TDD), unit tests are written before the code implementation. This approach ensures that each unit of code is thoroughly tested before it's even created, helping to identify and prevent defects early in the development process.
Consider a scenario where a software system is expected to accommodate future changes due to evolving market demands. What type of maintenance would be crucial and why?
- Adaptive Maintenance
- Corrective Maintenance
- Perfective Maintenance
- Preventive Maintenance
In this scenario, where the software needs to accommodate future changes due to evolving market demands, adaptive maintenance is crucial. Adaptive maintenance involves making changes to the software to ensure it remains functional and relevant in the face of changing requirements. This type of maintenance is essential to keep the software in sync with market needs.
