A _______ review is a detailed evaluation by a person or group other than the originator to consider its adherence to standards, procedures, and requirements.
- Formal
- Code
- Technical
- Informal
A formal review involves a thorough evaluation of a work product by individuals other than the originator. The focus is on assessing its adherence to established standards, procedures, and requirements to ensure quality and consistency.
Software verification is concerned with the process of checking that a product, system, or component meets specified ______.
- Deadlines
- Quality standards
- Budgets
- Color schemes
Software verification involves checking that a product, system, or component meets specified quality standards. This process ensures that the software meets the predefined quality criteria, such as functionality, reliability, and performance.
Consider a scenario where a software product passed all stages of verification but encountered several issues during validation. What could be the potential reasons, and how could these issues be mitigated in future projects?
- The software was over-verified
- The software wasn't verified properly
- The software was perfectly developed
- Validation is not necessary
In this scenario, the potential reason for encountering issues during validation could be over-verification. Over-verification may lead to a false sense of confidence that the software is free of issues when, in fact, it isn't. To mitigate such issues in future projects, it's essential to strike a balance between verification and validation activities, ensuring that both are performed adequately without overemphasizing one over the other.
Envision a scenario where a unit has passed all Unit Tests but is still exhibiting unexpected behavior when integrated into the full software system. What might be occurring, and how could this issue be diagnosed and resolved?
- The unit testing process is flawed
- The unit is likely interacting with other units differently in the integrated system
- Unit tests are not needed in this scenario
- The full system is perfect
If a unit passes all unit tests but exhibits unexpected behavior in the integrated system, it's likely due to the unit interacting with other units differently in the integrated environment. To diagnose and resolve the issue, comprehensive integration testing should be conducted to identify the discrepancies in behavior and rectify them.
What are the challenges encountered when automating the system testing phase in a traditional software development environment?
- Lack of skilled testers
- Inadequate test coverage
- High level of collaboration
- Frequent code changes
Automating the system testing phase in a traditional software development environment often faces challenges related to inadequate test coverage. In this context, the term "traditional" typically implies sequential development models like the Waterfall, where testing comes late in the process. Test coverage issues can arise due to limited time and resources available for comprehensive testing.
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.
