How does adhering to the principle of "Keep It Simple, Stupid" (KISS) in coding best practices contribute to software maintainability?
- It increases development time
- It leads to more bugs and errors
- It makes code complex and harder to understand
- It simplifies code, making it easier to maintain
Adhering to the KISS principle simplifies code, making it easier to understand and maintain. Complex code can lead to difficulties in maintaining and debugging.
In the SDLC, which phase involves ensuring that the software meets the specified requirements and is free of bugs?
- Analysis Phase
- Design Phase
- Maintenance Phase
- Testing Phase
The Testing Phase in the SDLC is dedicated to verifying that the software meets specified requirements and is free of bugs. This phase ensures the software's quality and functionality.
In _____ deployment, new features are incrementally rolled out to the user base, allowing for continuous feedback and adjustments.
- Agile
- Incremental
- Prototype
- Waterfall
In Agile deployment, new features are incrementally rolled out to the user base, allowing for continuous feedback and adjustments throughout the development process.
What type of testing is performed to ensure that the individual units or components of a software system are working correctly?
- Acceptance Testing
- Integration Testing
- System Testing
- Unit Testing
Unit Testing is the type of testing performed to verify that individual units or components of a software system work correctly. It focuses on isolated testing of these units to identify and address defects at an early stage.
What are the implications of not adhering to design principles like SOLID in a large-scale software project?
- Easier debugging and testing
- Improved scalability and performance
- Increased development speed and reduced cost
- Reduced code readability and maintainability
Not adhering to design principles like SOLID in a large-scale project can lead to reduced code readability and maintainability. This can result in increased technical debt, making it challenging to modify, expand, or maintain the software in the long term. SOLID principles promote code quality and long-term maintainability.
The _____ deployment strategy involves testing the new release on a subset of the production environment before full deployment to identify any potential issues.
- Blue-Green
- Canary
- Rolling
- Shadow
The Canary deployment strategy involves testing a new release on a small subset of the production environment before full deployment. It helps identify potential issues or bugs, reducing the risk to the entire system.
Which testing framework is commonly used for unit testing in Java applications?
- Cucumber
- JUnit
- Selenium
- TestNG
JUnit is a widely used testing framework for unit testing in Java applications. It provides annotations, assertions, and test runners to facilitate the testing of Java code, making it a popular choice for developers.
Which of the following is a common technique used for requirements validation?
- Code review
- Coffee breaks
- Team building exercises
- Writing user stories
Code review is a common technique for requirements validation, as it involves examining the code to ensure that it aligns with the specified requirements, enhancing quality and accuracy.
How can performance testing metrics be effectively used to optimize the user experience?
- By comparing with competitors
- By identifying bottlenecks
- By ignoring them entirely
- By increasing hardware resources
Performance testing metrics can be effectively used to optimize the user experience by identifying performance bottlenecks and issues in the application, enabling targeted improvements for a smoother user experience.
Agile methodologies seek to address the SDLC limitation of _____ by promoting continuous feedback and iterative development.
- Excessive documentation
- Lack of feedback
- Slow development
- Waterfall model
Agile methodologies aim to address the SDLC limitation of Lack of feedback by promoting continuous feedback and iterative development. In traditional SDLC models like the Waterfall model, feedback is typically limited until the end, whereas Agile methods emphasize ongoing collaboration, feedback, and adaptability, resulting in more responsive development processes.
