Debugging best practices

According to the training, how can developers ensure they are prepared for debugging?

• By having access to all necessary systems and tools

• By specializing in one tool only

• Ignoring external tools like AWS CloudWatch

• Relying solely on theoretical knowledge

What was Neal's primary approach to troubleshooting the issue presented in the demonstration?

• Guessing the problem based on past experiences

• Reviewing the stack trace for clues

• Ignoring the error messages

• Consulting an external expert immediately

Which of the following tools or resources did Neal emphasize the importance of for effective debugging?

• CloudWatch

• External forums

• Log files

• Stack traces

What was a key factor Neal considered when examining the logs?

• The color of the logs for easier reading

• The version of the application where the error occurred

• Only the latest entries in the log files

• The aesthetic presentation of the logs

How did Neal suggest narrowing down the cause of a bug?

• By changing one variable at a time

• By making multiple changes simultaneously to save time

• By focusing on the most complex parts of the code first

• By starting with the data and working backwards

Which approach did Neal take to understand the context of the error?

• Guessing based on similar past issues

• Asking colleagues for their opinion without checking the logs

• Using a specific commit to browse the relevant version of the code

• Ignoring the environment where the error occurred

In Neal's demonstration, what was highlighted about using AWS tools like CloudWatch?

• They are irrelevant for modern debugging techniques

• They can provide a cross-node perspective in multi-node environments

• They are too complex to be useful for debugging

• They should only be used by AWS certified professionals

According to Josh, what is a significant consideration when debugging in a production environment with Casetivity?

• The statelessness of the application and the implications for user session tracking.

• The exclusive use of physical servers over cloud infrastructure.

• The reliance on manual log file analysis without tools.

• Ignoring memory-related issues as they are self-resolving.

When using an Integrated Development Environment (IDE) for debugging, what is the difference between the "Step Over" and "Step Into" actions?

• "Step Over" executes the current line of code and moves to the next one, while "Step Into" dives into the methods called by the current line to allow debugging inside them.

• "Step Over" and "Step Into" perform the same action, but "Step Into" has a higher priority if both are used simultaneously.

• "Step Over" pauses the execution at the next breakpoint, while "Step Into" skips breakpoints and executes the rest of the program.

• "Step Over" exits the current method and returns to the caller method, while "Step Into" pauses the execution at the first line of the current method.

During a debugging session in an IDE, how can "Watch Variables" and "Set Value" features help improve the debugging process?

• "Watch Variables" allows you to monitor the changes in the value of specific variables in real-time, while "Set Value" enables you to manually change the value of a variable during the debugging session to test different scenarios.

• "Watch Variables" and "Set Value" are only useful for debugging multi-threaded applications and provide no benefits for single-threaded applications.

• "Watch Variables" pauses the program execution whenever the watched variable changes, while "Set Value" automatically adjusts variables to their optimal values as determined by the IDE.

• "Watch Variables" compiles a list of unused variables for optimization, and "Set Value" optimizes the memory allocation for the selected variables.
