The quality/ability/extent of being debuggable.
Debugability in systems refers to the ease with which a system can be debugged to identify, diagnose, and fix defects or issues. It involves providing the tools, processes, and capabilities necessary to efficiently trace and resolve problems within the system.
As a system quality attribute, debugability focuses on the inherent design characteristics of a system that make it easier to debug.
- Traceability: The ability to trace the flow of execution and data through the system.
- Logging: Comprehensive logging of system events and states.
- Error Reporting: Clear and detailed reporting of errors and exceptions.
As a non-functional requirement (NFR), debugability defines the requirements that ensure the system can be debugged efficiently and effectively.
- Instrumentation: The system should be instrumented to provide detailed insights into its internal state.
- Diagnostics: Built-in diagnostic tools to help identify and resolve issues.
- User-Friendly Error Messages: Error messages should be clear and informative, guiding the user toward resolution.
As a cross-functional constraint, debugability impacts various aspects of system design, development, and operation, requiring collaboration across different teams to ensure the system can be easily debugged.
- Consistency: Maintaining consistent logging and error reporting across all components of the system.
- Documentation: Providing comprehensive documentation on how to debug the system.
- Maintainability: Ensuring that debugging capabilities do not negatively impact system maintainability.
To implement debugability:
- Implement Comprehensive Logging: Ensure that all significant events and states are logged with sufficient detail.
- Use Structured Error Reporting: Implement structured and informative error reporting mechanisms that guide the user toward resolution.
- Provide Traceability Tools: Include tools that allow developers to trace the execution flow and data paths within the system.
- Enable Diagnostic Modes: Create diagnostic modes that can be activated to gather more detailed information when issues arise.
- Integrate Debugging Tools: Integrate with external debugging tools and platforms to facilitate efficient issue resolution.
- Maintain Detailed Documentation: Provide detailed documentation on debugging procedures, common issues, and their resolutions.
- Ensure Code Readability: Write clean, readable, and well-documented code to facilitate easier debugging.
- Incorporate Automated Testing: Use automated testing to catch issues early and make debugging more manageable.
- Develop Clear Error Messages: Design error messages to be clear, concise, and informative, helping users and developers understand the issue quickly.
- Perform Regular Reviews: Conduct regular reviews and updates to the system’s debugging capabilities to ensure they remain effective and up-to-date.
Define debuggable: Debuggable refers to a software application or program that is designed to be easily and effectively diagnosed and corrected for any bugs, errors, or problems that may arise during its development or use. It is a quality that allows developers, testers, and system administrators to locate and fix any issues that may occur in the application, ensuring its optimal performance and functionality. Debuggable applications are essential for minimizing downtime, improving user experience, and maintaining the overall health and stability of software systems.

Wikipedia: Debugging: In computer programming and software development, debugging is the process of finding and resolving bugs (defects or problems that prevent correct operation) within computer programs, software, or systems. Debugging tactics can involve interactive debugging, control flow analysis, unit testing, integration testing, log file analysis, monitoring at the application or system level, memory dumps, and profiling.

Dictionary: debug: to detect and remove defects from a system, or errors from a computer program.
