Coding Practices Day 5

What is the recommended practice for managing software versions in a robotics project?

• Use a single version for all software components throughout the project
• Frequently update all components to their latest versions regardless of compatibility
• Maintain a version control system to track changes and manage different versions
• Avoid updating any software components once the project has started

Answer explanation

Managing software versions through a version control system allows for tracking changes, managing different versions, and ensuring compatibility across components, which is crucial for a stable and functional robotics system.

Why is code documentation considered a critical practice in robotics software development?

• It helps in keeping code simple

• It ensures the code runs faster
• It facilitates easier understanding, maintenance, and collaboration among team members
• It is required for passing software audits

Answer explanation

Proper documentation ensures that code is understandable and maintainable, which is essential for collaboration and long-term project success.

Which of the following is a recommended practice for testing in robotics software development?

• Test only the final integrated system to save time
• Perform "unit testing" (running parts in sim and real) on individual components and integration testing on the complete system
• Rely solely on simulations for testing to avoid hardware issues
• Test each component separately without integration tests

Answer explanation

Both unit testing and integration testing are important. Unit testing ensures each component functions correctly in isolation, while integration testing ensures that components work together as intended.

What is the best practice for handling errors in robotics software?

• Ignore minor errors to save time
• Log errors and implement error-handling mechanisms
• Fix errors only if they cause system crashes
• Reboot the system whenever an error occurs

Answer explanation

Logging errors and implementing error-handling mechanisms helps in diagnosing and fixing issues systematically, which is crucial for reliable software performance.

In terms of collaboration and code sharing, what is a good practice?

• Each team member works on separate codebases without merging
• Use collaborative tools like Git to manage and share code
• Share code only through email attachments
• Avoid using any version control systems to keep the process simple

Answer explanation

Using collaborative tools like Git allows multiple team members to work on the same codebase efficiently, track changes, and manage contributions, which enhances teamwork and project coherence.

Why is it important to conduct code reviews (checking others code) in a robotics software project?

• To ensure that only one person is responsible for the entire code
• To identify and fix bugs before they become larger issues
• To add unnecessary complexity to the development process
• To delay the project timeline intentionally

Answer explanation

Code reviews help in identifying and fixing bugs early, ensuring code quality, and facilitating knowledge sharing among team members.

What should be included in a comprehensive software testing plan?

• Only tests for the most critical functions
• Tests for all possible edge cases and system behaviors
• Tests only for user interface elements
• Randomized tests without a specific focus

Answer explanation

A comprehensive software testing plan includes tests for all possible edge cases and system behaviors to ensure thorough validation of the software's functionality and reliability.

What is a recommended practice for ensuring code quality in a robotics project?

• Allowing each developer to follow their coding standards
• Enforcing a consistent coding style and standards across the team
• Writing code without any comments to make it more efficient
• Relying on automated tools exclusively for code quality

Answer explanation

Enforcing a consistent coding style and standards ensures that the codebase is uniform, readable, and maintainable, which is crucial for team collaboration and long-term project success.
