The _____ prototype is used to explore specific areas of the system where there is a high level of technical risk.
- Final
- Horizontal
- Throwaway
- Vertical
The "Horizontal" prototype is employed to explore areas of the system with high technical risk. It focuses on integrating different system components to test their interactions. This type of prototype helps identify and address technical challenges.
Discuss the trade-offs between normalization and denormalization in database design, particularly in the context of read-heavy applications.
- Normalization is always better
- Denormalization is always better
- Both have no impact on read-heavy applications
- The trade-offs depend on specific requirements
Normalization and denormalization are design strategies in database systems. In read-heavy applications, normalization reduces redundancy but may slow down queries due to multiple joins. Denormalization can improve read performance but may increase redundancy and maintenance complexity. The choice depends on the specific application requirements.
What is a crucial consideration while performing integration testing in a system with multiple interconnected modules?
- Ignoring the order of integration
- Testing each module in isolation
- Ensuring proper data flow between modules
- Avoiding interaction testing
In a system with multiple interconnected modules, a crucial consideration during integration testing is ensuring proper data flow between the modules. This involves validating that data is passed correctly and processed as expected when modules interact.
Why is regression testing crucial when implementing a new feature within an existing system?
- It speeds up the development process
- It helps reduce the cost of development
- It ensures that new features do not break existing functionality
- It is a formality without much impact
Regression testing is crucial when implementing a new feature within an existing system because it helps ensure that the introduction of new features does not lead to the breaking of existing functionality. This is essential for maintaining the software's stability and quality.
_____ testing, a type of white box testing, ensures that every path in the code is executed at least once.
- Unit
- Integration
- System
- Path
"Path" testing, a type of white box testing, ensures that every path in the code is executed at least once. It aims to cover all possible execution paths through the code to find potential issues.
Consider a project where the client is unsure about the specifications and expects them to evolve throughout the development process. Discuss the possible challenges in Quality Assurance when using the Waterfall model.
- Flexibility and adaptability
- Frequent scope changes
- Limited documentation
- Rapid development pace
In a Waterfall model, frequent changes in project scope can pose significant challenges to Quality Assurance. Since the requirements are expected to be well-defined upfront, any scope changes can lead to discrepancies between what was initially planned and what is being delivered, making it difficult to maintain quality standards.
White box testing primarily focuses on ______, ensuring that the internal operations perform correctly.
- User interface design
- External behavior
- Internal code structure
- Documentation
White box testing primarily focuses on the internal code structure, ensuring that the internal operations of the software perform correctly. It checks the correctness of individual code segments and their interaction within the application.
How does the system testing phase align with quality assurance protocols to ensure the reliability of the software product?
- By minimizing testing efforts
- By focusing on quantity over quality
- By validating against the software requirements
- By avoiding user feedback
The system testing phase aligns with quality assurance protocols by validating the software against its requirements. This ensures that the software meets the specified criteria and functions as intended, contributing to its reliability.
How does the Configuration Control within SCM enhance the software development process?
- It limits access to project documents
- It hinders collaboration among team members
- It ensures proper tracking and management of changes
- It slows down the development process
Configuration Control in SCM enhances the software development process by ensuring proper tracking and management of changes. It helps in maintaining consistency and integrity in the software configuration, allowing teams to make informed decisions about changes, and preventing unauthorized alterations to project documents.
The practice of writing tests before writing the code they test is known as ______.
- Test-Driven Development (TDD)
- Code-First Development
- Test-Last Development
- Test-Code Synchronization
The practice of writing tests before writing the code they test is known as Test-Driven Development (TDD). TDD is a software development methodology that emphasizes writing unit tests before implementing the code. This approach helps ensure that the code functions correctly and meets the requirements defined by the tests.
