Verification is typically performed by the ______ team, while validation is typically performed by the ______ team.
- Development, Testing
- Testing, Development
- Quality Assurance, Project Management
- Business Analysts, Customers
Verification, in the context of software engineering, is typically performed by the testing team. It involves checking whether the software meets its specified requirements. Validation, on the other hand, is typically performed by the development team, ensuring that the software meets the customer's needs and expectations.
In a scenario where a security audit for a software application is necessary, how might white box testing be utilized to identify potential vulnerabilities in the code?
- By ignoring the code and focusing only on user interface vulnerabilities
- By running penetration tests from an external perspective
- By analyzing the code, identifying weak points, and simulating attacks
- By relying on automated testing tools without code analysis
White box testing, in a security context, involves analyzing the code to identify potential vulnerabilities, such as code injection or security weaknesses, and then simulating attacks to verify their presence.
Which design pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable?
- Singleton Pattern
- Factory Pattern
- Strategy Pattern
- Prototype Pattern
The Strategy design pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. It allows you to define a set of algorithms, encapsulate them in separate classes, and make them interchangeable at runtime, enabling the client to choose the appropriate algorithm without altering its code. This pattern is especially useful when you want to provide multiple ways to accomplish a task, such as sorting, without changing the client code.
The quality attribute _____ refers to the speed with which the software operates and processes data.
- Reliability
- Performance
- Security
- Usability
Performance is a quality attribute that focuses on the speed and efficiency of a software system. It involves how quickly the software performs tasks and processes data. Good performance ensures that the software is responsive and meets user expectations.
Regression testing is vital for ensuring that new changes do not adversely affect the existing stability of the software.
- Features
- Stability
- Documentation
- Performance
Regression testing is essential to confirm that new changes do not negatively impact the existing stability of the software. It helps ensure that the software continues to function as expected after modifications or updates.
Discuss the potential pitfalls of solely relying on Black Box Testing for a software testing strategy.
- Limited code coverage
- High maintenance overhead
- Low testing repeatability
- Limited understanding of user needs
Black Box Testing primarily focuses on input and output behavior, which may result in limited code coverage. It might miss certain internal issues and code vulnerabilities, potentially leading to incomplete testing.
Which SDLC model promotes iterative work sequences that are commonly known as sprints?
- Agile
- Spiral
- V-Model
- Waterfall
The Agile SDLC model promotes iterative work sequences commonly known as sprints. Agile is characterized by its flexibility, customer collaboration, and the ability to adapt to changing requirements throughout the project.
What is the primary focus of the ISO/IEC 25010 software quality standard?
- Process improvement
- Product quality characteristics
- Security standards
- Project management
The ISO/IEC 25010 software quality standard primarily focuses on product quality characteristics. It defines a set of quality attributes like performance, usability, reliability, and others, which are essential for assessing and evaluating software quality.
Envision a situation where a legacy system is becoming increasingly difficult and expensive to maintain. Discuss how software evolution models might be utilized to address the challenges posed by the outdated system.
- Continue maintaining the legacy system
- Employ a reengineering approach
- Transition to a different legacy system
- Abandon the system
When dealing with an outdated and expensive-to-maintain legacy system, a reengineering approach can be beneficial. Reengineering involves analyzing, redesigning, and re-implementing the system to enhance its maintainability and reduce costs. This approach helps address challenges posed by legacy systems effectively.
Which of the following is a legitimate use of reverse engineering in software development?
- Unauthorized software duplication
- Understanding how a third-party application works
- Software piracy
- Stealing proprietary code
A legitimate use of reverse engineering in software development is to understand how a third-party application works. This can be important for interoperability, integration, or troubleshooting issues with software from external sources.
