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.
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.
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.
Traditional SDLC models often face the limitation of ______ when dealing with changing requirements.
- Adaptability
- Lack of planning
- Limited documentation
- Rigidity
Traditional SDLC models often face the limitation of rigidity when dealing with changing requirements. These models often have well-defined phases and may struggle to accommodate changing requirements, making them less adaptable.
The principle of _______ in Object-Oriented Programming suggests that a class should have only one reason to change.
- DRY
- KISS
- SOLID
- YAGNI
The principle of SOLID in Object-Oriented Programming, specifically the Single Responsibility Principle (SRP), suggests that a class should have only one reason to change. This promotes maintainability and a clear design.
The _____ SOLID principle emphasizes that high-level modules should not depend on low-level modules, but they should depend on abstractions.
- Dependency Inversion
- Interface Segregation
- Liskov Substitution
- Open-Closed
The Dependency Inversion SOLID principle states that high-level modules should not depend on low-level modules; both should depend on abstractions. This promotes the use of interfaces or abstract classes to achieve this separation of concerns, enhancing maintainability and flexibility in the software.
You are tasked with minimizing downtime during deployment in a highly scalable application. Which CI/CD strategy would be most effective in achieving this?
- Blue-Green Deployment
- Canary Deployment
- Feature Toggles (Feature Flags)
- Rolling Deployment
Blue-Green Deployment is a strategy where you have two identical environments (blue and green), allowing seamless switching with minimal downtime during deployment.
In a project following Agile methodology, how would a team ensure that both functional and non-functional requirements are considered and implemented during the development sprints?
- Agile focuses on functional requirements, and non-functional requirements are addressed in later stages.
- Agile incorporates both functional and non-functional requirements by including them in user stories and tasks during each sprint.
- Agile teams rely solely on non-functional requirements documentation.
- Non-functional requirements are ignored in Agile projects.
Agile teams ensure that both functional and non-functional requirements are considered by incorporating them into user stories and tasks. This allows non-functional aspects like security, performance, and compliance to be addressed iteratively throughout the development process, rather than deferring them to later stages.
A software development team is working on a project with frequent changes in design requirements. Which prototyping tool would be best suited for quickly iterating and testing design changes?
- High-Fidelity Interactive Prototyping
- Low-Fidelity Paper Prototyping
- UML Diagrams
- Wireframing
High-Fidelity Interactive Prototyping tools, like mockups and interactive prototypes, are best suited for quickly iterating and testing design changes, making them ideal for projects with evolving design requirements.
The ________ in a bug tracking system provides detailed information about a bug, including its status, priority, and description.
- Bug report
- Bug repository
- Bug tracker
- Bug triage
In a bug tracking system, the bug tracker is the component that provides detailed information about a bug. It includes its status, priority, description, and other relevant details, allowing for effective management and resolution of bugs.
How do tools like Selenium WebDriver facilitate automated testing in software development?
- They automate the entire software development process.
- They only work with Java applications.
- They provide a framework for automating web application testing.
- They require manual test case creation.
Selenium WebDriver is a tool that provides a framework for automating web application testing. It allows testers to write test scripts in various programming languages and automate the testing of web applications across different browsers.
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.
