Error Handling in Automation Code

1. When should custom exceptions be created in automation frameworks?

Never; always use built-in exceptions

When standard exceptions don't clearly describe domain-specific errors

For every possible error condition

Only for logging purposes

2. In automation code, when should you use error suppression (ignoring exceptions)?

Always, to avoid disruptions

Rarely; only when the error is truly non-critical and logged

Never; all errors must cause failures

Only for network operations

3. What is the relationship between error handling and system reliability in automation?

Error handling reduces reliability

They are unrelated

Proper error handling increases system resilience and uptime

Error handling only matters for testing

4. How does structured logging improve error handling in automation?

It makes logs harder to parse

It enables automated analysis and filtering of error patterns

It eliminates the need for error recovery

It prevents errors from occurring

5. When implementing error handling, what should be avoided?

Using try-catch blocks

Catching broad exception types that hide root causes

Logging errors

Recovering from failures

6. What is the role of error context in automation debugging?

It slows down error detection

It provides state information to understand why an error occurred

It eliminates the need for logging

It prevents future errors

7. How should idempotency be implemented in error-prone automation operations?

By retrying without checking if operation already succeeded

By ensuring the same operation produces the same result regardless of retries

By avoiding all retries

By logging all operations without recovery

8. What is the purpose of a dead letter queue in automation systems?

To permanently delete failed messages

To store messages that fail processing for later analysis

To speed up message processing

To encrypt all messages

9. Which monitoring approach helps detect errors in running automation workflows?

Avoiding logs to reduce storage

Health checks, alerting, and centralized logging

Manual inspection of every operation

Disabling error reporting

10. What does graceful degradation mean in automation error handling?

Allowing the system to crash immediately

Reducing functionality while maintaining core operations during failures

Ignoring all errors silently

Retrying indefinitely without limits

11. What is the primary purpose of error handling in automation code?

To prevent all errors from occurring

To detect, log, and recover from failures gracefully

To slow down execution for safety

To eliminate the need for testing

12. What is the difference between an exception and an error in automation code?

No difference; terms are interchangeable

Exceptions are recoverable; errors are typically fatal

Errors are recoverable; exceptions are fatal

Exceptions only occur in loops

13. How should sensitive data like API keys be handled in error logs?

Log them in plain text for debugging

Mask or exclude them from logs

Include them for faster troubleshooting

Store them unencrypted in error messages

14. What is a finally block used for in error handling?

To catch all types of errors

To execute cleanup code regardless of whether an exception occurred

To prevent exceptions from being raised

To log errors only

15. Which pattern prevents cascading failures in distributed automation systems?

Circuit breaker pattern

Infinite retry loops

Ignoring all errors

Synchronous blocking calls

16. What is exponential backoff in automation error handling?

Increasing wait time between retry attempts geometrically

Decreasing wait time between retries

Stopping immediately on first error

Logging errors exponentially

17. In error handling, what should be logged to aid troubleshooting?

Only successful operations

Error message, stack trace, timestamp, and context

Passwords and API keys for debugging

User input without filtering

18. What is the main benefit of retry logic in automated workflows?

It increases code complexity

It masks underlying system problems

It allows transient failures to recover without human intervention

It eliminates the need for error logging

19. Which exception type typically indicates a temporary network issue in automation?

SyntaxError

TimeoutError or ConnectionError

NameError

TypeError

20. In automation frameworks, what does a try-catch block accomplish?

It prevents network timeouts

It wraps code to catch and handle exceptions without stopping execution

It removes all syntax errors automatically

It encrypts sensitive data in logs
