What is Debugging and Why we need to Debug?
Debugging is a very important aspect of programming and engineering. It's about running the code and Finding or Detection the Bug. The debugging Important Factors to Consider are What the bug or fault is, Where it has occurred, How it is caused.
Programming has the power to create any virtual experience anyone can imagine. It's fun as long as we're stuck with bugs. And we can spend up to 50% of our time solving them.
“A debugger is an essential and more powerful tool for the developers to help them find the errors and understand the codes in a much better way.”
What is Debugging?
Debugging, in the world of computer programming, engineering, is the multistep process of detecting and removing of existing ‘bugs’. During the Software development process testing, updating, troubleshooting, and maintenance come. Typically, the software contains errors and bugs, which are usually removed. In a software code that can cause it unexpectedly or by accident. Sometimes debugging becomes more difficult when different modules are tightly coupled and any changes in one module can cause more bugs to appear in another, sometimes compared to coding one program It takes longer to debug in.
Steps involved in debugging are:
Identification of the problem and ready the report.
Describe the bug and Assigning the report to the software engineer.
Defect Analysis using modeling, documentation, finding and testing candidate flaws, etc.
Defect Resolution by making the required changes to the system. Based on that try to find the cause of the bug.
During the fix existing bug check that any new bug does not occur.
Why we need to Debug?
Because we all make mistakes and Debugger plays an important role in the development of the project, Debugging certainly helps and breaks complex problems into simple ones to keep things simple And the process of debugging while written the code of the software faster. Do not make any syntactic or other errors while implementing the code. Then, it continues in successive stages as code is combined with other units of programming to form a software product.
A debugger helps to allow to stop your code when it gets to the place where you suspect a problem of logic or implementation, and to investigate whether it is really doing what you thought it would. You could do the same thing by adding printouts to your code, but it's a lot less convenient and flexible.
Identify the Error:
Bad detection of an error can lead to wasted development time. It is common that production errors reported by users are difficult to interpret and sometimes the information we receive is misleading. This is an import to identify the actual error.
Find the Error Location:
If you need to go through the code to correctly identify the error, then find the exact point where the error is located. In this step, you need to focus on finding the error rather than understanding it.
Analyze the Error:
In this step for the error location and analyze the code you need to use a bottom-up approach. This helps you in understanding the error and Analyzing bugs.
Prove the Analysis:
Once you analyze the original bug, you need to find some more errors that may appear on the application. This step is about writing automated tests for these fields with the help of a test framework.
Cover Lateral Damage:
This stage used for you need to create or gather all the unit tests for the code where you are going to make changes.
Fix & Validate:
The final stage is the fix all the errors and test the application.
“Developers debug the codes more than running”
So debugging the right way will help you to logical and analytical understanding, is the most important skill a developer can have.
Qualifies you to be responsible for a valuable product and a valuable team to effectively find and eliminate errors and bugs. In the end it greatly increases your own value, because you are a problem solver.
