What is it:
Software debugging is the process of finding, and fixing errors, bugs, or defects in a computer program. It is a crucial part of the software development lifecycle as part of the Implementation and Maintenance steps. It ensures that the software functions as intended, meets specified requirements, and operates reliably, ultimately enhancing the software's overall quality and performance.
Key Aspects of Software Debugging:
• Issue Identification
Reproduce and understand the problem's nature.
• Utilizing Debugging Tools
Use an Integrated Development Environment (IDE) and logging for effective debugging.
• Setting Breakpoints
Breakpoints can be set in the code at specific lines where the issue is suspected to occur, program
execution will pause, when a breakpoint is reached while debugging.
• Stepping Through Code
Pinpoint the issue, by examining the code's execution line by line.
• Variable Inspection
Scrutinize real-time variable values for anomalies.
• Fixing the Problem
Address identified issues, by implementing necessary code changes.
• Regression Testing
Ensure that fixes don't introduce new problems, through comprehensive testing.
Record the debugging process for future reference.
Software debugging involves replicating reported issues; utilizing debugging tools; inspecting code and variables; applying fixes; testing; and documenting the process. Successful debugging ensures the production of robust, reliable, and error-free software.
