In this article, you will get to know about debugging. What is it, process, strategies, and tools for debugging. You will get whole knowledge about it. Happy reading!!
Introduction To Debugging
The process of finding and removing computer program bugs, errors, or abnormalities is called debugging, it is efficiently handled by software programmers via debugging tools. To allow proper program operation according to set specifications, it checks, detects, and corrects errors or bugs.
To develop software programs it needs to undergo heavy testing, updating, troubleshooting, and maintenance. Normally, the software contains errors and bugs, which are routinely removed.
Process Of Debugging
Debugging involves various steps. These steps include:
- Identifying the error – It saves time and avoids the errors at the user site. Identifying errors at an earlier stage helps to minimize the number of errors and wastage of time.
- Identifying the error location – The exact location of the error should be found to fix the bug faster and execute the code.
- Analyzing the error – To understand the type of bug or error and reduce the number of errors we need to analyze the error. It is also possible that if we solve one bug it may lead to another bug that stops the application process.
- Prove the analysis – Once the error has been analyzed, we need to prove the analysis. It uses a test automation process to write the test cases through the test framework.
- Cover the lateral damage – The bugs can be resolved by making the appropriate changes and move onto the next stages of the code or programs to fix the other errors.
- Fix and Validate – This is the final stage to check all the new errors, changes in the software or program, and executes the application.
Strategies For Debugging
- Study the system for a larger duration in order to understand the system. This study helps debugger to construct different representations of systems, with this debugging can be done according to need.
- Backward analysis problem, includes tracing the program backward from the location of the failure message in order to identify the region of faulty code.
- Forward analysis of the program involves tracking the program forwards using breakpoints or print statements at different points in the program and studying the results.
- The software which has similar problems, past experience to debug can be used to solve such problems
Tools For Debugging
The computer program that is used to test and debug other programs, is called debugging tool. Some of the widely used debuggers are:
- Radare2
- WinDbg
- Valgrind
