• Extensive user manuals and guides.

12. How should code reuse be reviewed?

• Refactoring code only for aesthetic purposes without functional improvements.
• Completely rewriting all existing code without any justification.
• Ignoring any existing libraries and creating new ones from scratch.
• Proper reuse of existing libraries, frameworks, or components, and ensuring that any dependencies are managed correctly and up-to-date.

13. What should be checked for compliance with coding standards?

• Company or project-specific coding standards and guidelines.
• The most popular coding styles online.
• The latest programming language features.
• Only personal preferences of the coder.

14. What are the benefits of using a code review checklist?

• It ensures that all code is perfect always.
• The code’s author will know why they should make a change.
• Reviewers will find all possible typos easily.
• Everyone agrees on every single line of code.

15. What is the recommended size of code to review at one time?

• 20-30 lines of code at a time.
• 50-100 lines of code at a time.
• 1000-1500 lines of code at a time.
• 200-400 lines of code at a time.

16. What should be verified during a code review?

• Only naming conventions and comments.
• Functionality, readability and maintainability, code structure and design, performance and efficiency, error handling and logging, and compliance with coding standards.
• Just checking for typos and formatting.
• All changes should be ignored if they work.

17. How should the code’s design be evaluated?

• By testing applications for hardware compatibility.
• Whether the code follows established design patterns and architectural guidelines, and whether it is modular and maintainable.
• By checking if the comments are clear and understandable.
• By ensuring that the code runs without any errors.

18. What should be checked for readability?

• Network connectivity and server uptime during review.
• Code optimization techniques and strategies.
• Proper indentation, consistent naming conventions, and appropriate use of comments to explain complex or non-obvious code segments.
• Availability of debugging tools and software.

19. How should maintainability be tested?

• Which graphic design software was used to create the UI elements.
• What the advertising budget is for the software product being developed.
• How frequently test cases are written for each function used in the code.
• Whether the code is easy to test and debug, whether it can be configured quickly to change data values, and whether it relies on functions or technology that should be phased out.

20. What should be considered for speed and performance?

• Consistent naming
• Strict indentation
• Detailed comments
• Inefficient loops

21. How should documentation be confirmed?

• By confirming it matches the color scheme of the application.
• Whether the documentation explains the code’s purpose, teaches the user how to use the code, and is clear and well-written.
• By checking if the comments are humorous and engaging.
• Through a simple count of the number of pages in the document.

22. How should naming conventions be inspected?

• By measuring code length
• By checking for clarity and context
• By analyzing execution speed
• By evaluating user feedback

23. What should be included in a code review checklist?

• Only comments and suggestions.
• Readability, security, test coverage, architecture, reusability, and compliance with coding standards.
• Only the number of lines in the code.
• Personal preferences of the reviewer.

24. Why is it important to document decisions during a code review?

• To reduce the number of comments on a code review.
• To make the coding process faster and easier.
• To avoid conflicts between team members in future projects.
• To ensure that all decisions and feedback are recorded and can be referred to later.

25. How should feedback be given during a code review?

• Harshly, without consideration for the author.
• Vaguely, avoiding specifics and details.
• Indifferently, with no context or reasoning.
• Respectfully, explaining the viewpoint, and justifying the comments.

26. What should be the focus of a code review checklist?

• Team social dynamics.
• Core issues.
• Aesthetic choices.
• Personal preferences.

27. How should the code’s functionality be verified?

• Whether the code implements the intended functionality, meets the specified requirements, handles edge cases and potential error scenarios appropriately, and its behavior is consistent with the project’s specifications.
• Checking only for syntax errors and warnings.
• Focusing solely on performance improvements.
• Reviewing just the formatting and indentation.

28. Why is it important to automate code reviews?

• To streamline the review process, reduce manual effort, and ensure consistency in feedback.
• To eliminate the need for human reviewers altogether.
• To ensure that every line of code is written perfectly without exceptions.
• To add more steps to the review and confuse the reviewer.

29. What should be the goal of ensuring consistent styles during a code review?

• To ensure every developer writes code in their own style.
• To increase the number of lines of code in the project.
• To complicate the review process with unnecessary guidelines.
• To make the code easier to understand and maintain by adhering to established coding conventions.

30. How should the code’s structure and design be evaluated?

• Whether the code is written in comments only and lacks actual implementation.
• Whether the code has too many unnecessary variables and lacks functions.
• Whether the code follows established design patterns and architectural guidelines, is modular and maintainable, and adheres to the principles of separation of concerns and single responsibility.
• Whether the code`s layout is visually appealing without regard to functionality.
