Log Levels vs Assertions
Developers should learn and use log levels to improve application observability and maintainability, as they enable efficient debugging by providing context-specific information without overwhelming logs meets developers should use assertions during development and testing to validate internal logic, preconditions, postconditions, and invariants, which helps identify bugs quickly and ensures code behaves as intended. Here's our take.
Log Levels
Developers should learn and use log levels to improve application observability and maintainability, as they enable efficient debugging by providing context-specific information without overwhelming logs
Log Levels
Nice PickDevelopers should learn and use log levels to improve application observability and maintainability, as they enable efficient debugging by providing context-specific information without overwhelming logs
Pros
- +For example, use DEBUG for detailed development insights, INFO for general operational events, and ERROR for critical issues that require immediate attention in production environments
- +Related to: logging-frameworks, application-monitoring
Cons
- -Specific tradeoffs depend on your use case
Assertions
Developers should use assertions during development and testing to validate internal logic, preconditions, postconditions, and invariants, which helps identify bugs quickly and ensures code behaves as intended
Pros
- +They are particularly useful in unit testing, debugging complex algorithms, and enforcing contracts in software design, but should be avoided in production code for performance and security reasons, as they can be disabled in many environments
- +Related to: unit-testing, debugging
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Log Levels if: You want for example, use debug for detailed development insights, info for general operational events, and error for critical issues that require immediate attention in production environments and can live with specific tradeoffs depend on your use case.
Use Assertions if: You prioritize they are particularly useful in unit testing, debugging complex algorithms, and enforcing contracts in software design, but should be avoided in production code for performance and security reasons, as they can be disabled in many environments over what Log Levels offers.
