What is the main objective of performance testing in software development?
- Ensure 100% code coverage.
- Identify and fix all defects.
- Validate user interface design.
- Verify if the software meets specified performance criteria
The main objective of performance testing is to verify if the software meets the specified performance criteria, such as response time, scalability, and resource utilization. It helps ensure the software's performance is acceptable.
The process of tracing and identifying the origin of requirements is facilitated by the use of a __________ matrix.
- Requirements
- Stakeholder
- Traceability
- Validation
Traceability matrices are used to trace and identify the origin of requirements. They help ensure that each requirement is linked to its source and that nothing is missed during the development process.
Imagine a scenario where a user identifies a bug in a mobile application and reports it through the app's feedback system. What steps would typically follow in the bug tracking and resolution process?
- The bug is documented and prioritized.
- The bug is fixed immediately.
- The bug is ignored by the development team.
- The user is asked for payment.
Bug tracking and resolution typically involve documenting the reported bug, prioritizing it based on its impact and severity, assigning it to a developer, fixing it, testing the fix, and then releasing an update. Ignoring or asking for payment is not standard practice.
Why is it important to clearly define both functional and non-functional requirements before the development phase begins?
- Clear requirements help in creating a shared understanding and reduce misunderstandings.
- It saves time if you define requirements later in the project.
- It's not essential; you can define them as you go.
- Non-functional requirements are less important than functional requirements.
Clearly defining both functional and non-functional requirements is crucial to ensure that everyone involved in the project understands what needs to be built. This shared understanding reduces misunderstandings and minimizes rework, leading to a more successful project.
What is the primary goal of using prototyping models in software development?
- To complete the project faster
- To create the final product early
- To document the requirements
- To identify and eliminate errors
The primary goal of using prototyping models in software development is to create an early version of the final product to better understand and validate the user requirements and design.
How does the Maintenance phase in the SDLC ensure the longevity and relevance of a software product?
- It adapts to changing needs
- It focuses on cost reduction
- It handles bug fixes
- It updates the user manual
The Maintenance phase in the SDLC ensures the longevity and relevance of a software product by adapting it to changing needs, adding new features, and addressing issues. It's not just about reducing costs or updating documentation; it's about keeping the software up-to-date and valuable to users over time.
Which SDLC model emphasizes iterative development and the necessity of maintaining a flexible approach to changes in the project?
- Agile Model
- Incremental Model
- V-Model
- Waterfall Model
The Agile Model emphasizes iterative development and flexibility. It involves short development cycles, frequent feedback, and adaptability to changes. This approach is well-suited for projects with evolving requirements.
One of the limitations of traditional SDLC is that testing is often relegated to the _____ phase, which can lead to delays.
- Development
- Planning
- Requirements
- Testing
One of the limitations of traditional SDLC is that testing is often relegated to the Development phase. This means that testing occurs late in the cycle, which can lead to delays and increased costs due to the identification and rectification of defects late in the process. It is more effective to incorporate testing earlier in the process to catch issues sooner.
What is the main purpose of using a testing framework like JUnit or TestNG?
- To automate unit and integration tests
- To create user interfaces
- To manage software development projects
- To write software documentation
JUnit and TestNG are testing frameworks that automate the execution of unit and integration tests, making it easier to validate code and improve software quality.
Which limitation of SDLC is highlighted by the need for extensive documentation in every phase?
- Excessive emphasis on user involvement.
- Lack of flexibility and adaptability.
- Lack of structure in SDLC.
- Potential for scope creep.
The extensive documentation requirement in traditional SDLC models underscores the limitation of rigidity and lack of adaptability to changing project needs, making it challenging to manage evolving requirements.
