Understanding the Bug
Understanding the bug in detail is the first step to fixing it. Gathering information from different sources, such as user feedback, logs, and bug reports, is essential.
In this session, we will cover the importance of bug reports, including the expected behavior, the actual behavior, and the steps required to reproduce the problem. We will also discuss the importance of categorizing bugs and prioritizing them based on severity, frequency, and impact.
Reproducing the Bug
It is essential to reproduce the bug for developers to understand it and determine the cause. This session will cover strategies to reproduce bugs, such as creating test cases in isolated environments and using debugging software.
We will also discuss the importance of giving clear instructions to help team members replicate the bug.
Analyzing and Debugging
After reproducing the bug, the next step is to debug and analyze the code to find the cause. Debugging methods such as logging, breaking points, and error tracking will be discussed.
We will also discuss the importance of collaboration and code review amongst team members in the debugging phase. In addition, we will discuss the value of maintaining a database or bug repository to record lessons learned and prevent similar problems from occurring again.
Developing and Testing the Fix
Developers must identify the cause of the bug and then develop a solution. In this session, we will cover best practices in developing bug fixes.
These include writing clean, modular code and following standards. We'll also discuss thorough testing.
We will discuss the importance of integration, unit, and regression testing to ensure that the bug fix doesn't introduce any new problems or regressions.
We will also explore the importance of using version control to manage code changes effectively.
Review, Deployment, and Postfix Verification
It is essential to review the entire fix before deploying it to ensure its quality meets coding standards. This article will examine the importance of automated code analysis and peer code review tools.
After the fix has been approved, the solution can be released to production. This section will discuss the importance of release management strategies, such as change management, versions, and rollback strategy.
We will also discuss postfix testing and monitoring to ensure the bug has been successfully fixed.
What Does A Software Bug Mean?
Bugs are errors in computer programs. A bug can appear at any point in the development of software, starting with the design and ending with the testing.
Bugs can occur when the software is used, and it doesn't work as expected.
What Exactly Is Bug-Reporting?
A bug report is the act of reporting a problem to a developer or another interested party. You provide details about the bug and steps to reproduce it when you file a bug.
The information provided by the user helps developers quickly identify and resolve the problem.

What Does Bug Fix Mean?
Bug fixes are changes to code which address a bug. A bug fix does not always mean that the issue has been resolved.
It could be just a temporary solution until a permanent one can be found.
Bug Fixing Made Easy
It is impossible to find the perfect solution for fixing bugs. Following a few guidelines will help you make the most of your bug-fixing efforts:
- You should try to replicate the bug with as much accuracy as you can.
It will allow you to pinpoint the exact problem and make sure that the fix you apply is successful.
- Before you send your change to the team of software developers, make sure that it is properly documented and has been tested.
It will prevent future conflicts and issues.
- You will waste time and frustration if you work on bugs which are not clear to you.
Techniques For Fixing Bugs
Some common ways of fixing bugs include:
-
Testing - Do not do anything until you have tested your software in an environment controlled.
You can then avoid embarrassing situations during real-time customer interaction.
-
Tutorials and Walkthroughs - When the bug involves a complex process or function, it may be useful to create a tutorial or walkthrough on how to resolve it.
It will allow users to get help as soon as possible.
-
Test Automation - Software that tests for bugs is a great way to automate the bug fix process.
You can then catch the bugs early and stop them from becoming a problem.
-
Rapid Prototyping - If you are trying to find a solution to a problem, you may want to prototype different solutions quickly to help you determine the most effective one and to minimize any impact to your users.
This is especially useful when you have multiple solutions that are not guaranteed to work.
-
Debugging - If all else fails to fix bugs, then debugging is the last resort.
It involves tracking down and solving the bug as fast as possible.
This can be time-consuming and difficult, but is usually the fastest and most efficient way to solve a software problem.
-
Tools - Many different tools can be used to debug and fix bugs.
These include debuggers and profilers.
Each tool has strengths and weaknesses, so it is crucial to choose the best one for your needs.

Bugs Are Expensive
We perceive bugs on a smaller scale as annoying annoyances which slow down the software development process and give users a bad impression of the final product.
When we zoom in, however, it becomes clear what the true cost of bugs is. Software errors cost the global economy more than $1 trillion per year, about the same as South Korea's GDP.
The report also found that the failure of software has caused 315 lost years and affected 4.4 billion people. The reputation of businesses is also severely damaged by software failures.
Tricentis found that the average loss of value for shareholders was $2.3 billion in just one day following announcing software failures. It's no wonder so many companies are silent about bugs.
Zooming back, you can see how the cost of fixing bugs increases as they are discovered. IBM claims that bugs discovered after a product's release can be 4 to 5x more expensive to fix than bugs found during the design stage, and up to 100x as costly as those discovered in maintenance.
Companies that rely on outdated methods for handling bugs and requests for features risk producing buggy software, and then paying a steep price.
Agile software development allows teams to be more flexible than ever before when it comes to adding new features, changing existing ones, or checking for bugs.
Agile Methods For Bug Management
You may be familiar with waterfall software development. The scope of waterfall projects are rigidly controlled and lack flexibility.
Agile software development, on the other hand, is about constant iteration and change to achieve customer satisfaction.
It's better to adopt an Agile approach from the beginning, rather than trying to fit outdated methods of managing bug reports and feature requests in an Agile development model.
Your Bugs Will Be Visible
A good software development team will keep a bug database. It's possible to track issues and bugs with Microsoft Excel.
However, there are many benefits to using an issue management system.
The Tracker is a project management software that supports real-time collaborative work around a prioritized shared backlog.
Pivotal Tracker is compatible with the leading issues tracking software, such as:
- Redmine is a project management tool and an issue tracker that's free, open-source and allows you to manage several projects.
- Bugsnag is a solution that helps you decide if it's better to fix bugs or build new features.
- Bugzilla is a popular defect tracking system developed by Mozilla and distributed under Mozilla Public License.
Bug tracking systems and issue trackers help to ensure that bugs found are corrected. They also bring the team closer together through better communication via chat.
Users can report bugs or make feature requests on their own applications.
Prioritize Your Bugs
If Agile teams let the bug backlog grow uncontrolled, they can become impossible to manage. Prioritizing bugs is important.
Bugs are usually prioritized based on their severity (S), or the impact they have on software quality. Priority and severity of bugs are important and should be addressed first.
Bugs that have the lowest severity and priority do not require immediate attention.
- These critical bugs cause a complete breakdown of the feature.
There is no workaround.
It is important to fix them as quickly as possible.
Usually, this means within 24 hours.
Priority -1 is sometimes assigned to bugs that result in significant memory leaks, meaning that the software cannot function.
- Bugs of high priority may affect important features or data and may or not have workarounds.
It's either difficult or not apparent to use a workaround, if one is provided.
Before a release, all high-priority issues should be addressed.
- Bugs of medium priority may affect non-critical information or minor functionality, but there are simple solutions.
Some cosmetic mistakes are classified as P3 bugs depending on the severity of their impact.
The medium-priority bug fixes don't have to be done before a release, they can wait until all the high-priority ones are resolved.
- Bugs of low priority do not affect functionality or data.
These are small bugs, like spelling mistakes and design discrepancies that can be corrected in the future.
They don't require immediate attention.
The 5 R’s: Why You Need A Process For Fixing Bugs
Even though software engineers make every effort to prevent bugs, they still manage to introduce some. Software teams who use every method from code reviews to test-driven design will still receive some defect reports, even if they are less severe.
If the customer reported it, then this situation is even worse.
Irrespective of what your team calls it, whether a bug, issue, observation, defect, or test failure (I am old-school), is there a specific process that they follow to resolve them? Some teams' definition of a process is "just fix it!" These same teams often have the favorite answer to testers ..."Well it works on my computer!".
We know that this response is unacceptable.
Other situations may occur when teams lack a mature process for defect resolution. These are some examples:
- It seems that the bug has been fixed but now I see another bug.
- It still occurs, although less often.
- This feature is no longer working.
- Although I no longer have the ability to reproduce this bug, I dislike how it works.
For custom software engineers to limit the number of situations that can occur, I have asked them to take five practical steps when fixing bugs.
These are: reproduce, root cause, resolve, regression, and retrospect. They are what I refer to as the "5 Rs of fixing bugs".
-
Reproduce: If it's not impossible, you should always try to replicate the bug before trying to fix it.
Do not assume that you will know where or what the bug is before writing code.
It's called "blind fixing".
This is like shooting a bow with closed eyes.
It's possible to hit the target because you know it well, but you are more likely to miss.
When your testing team says, "Your fix did not work, the bugs are still there,"
-
Root Cause: Understand the root cause before you fix the bug.
It is dangerous to make changes before understanding the cause.
You may be only fixing the symptom, and not the actual problem.
This is another example of blind fixing.
It may manifest differently at different times, or be harder to reproduce.
It will be much more expensive than fixing the root cause at the beginning.
You and your testing team will be more confident in the fix you'll have once you understand what caused it.
-
Resolve: There are usually 2 or 3 possible solutions to a bug.
The best solution is not always the fastest or first one that comes to mind.
You may discover that a code works as intended or that a workaround will be needed because of business priorities.
In these rare instances, always review the resolution with your team.
-
Regression: You need to test every code path that is affected by the change.
Unintentionally, you may introduce a new defect as a result of code changes.
Bug fixes are included in this category and it is more of a problem when a release date is near.
Use continuous integration/test automation if you have it.
This is a good time to create the unit tests that you missed.
-
Retrospect: Ask yourself why this bug was created in the first instance.
What went wrong? What lessons can your team and you learn from the mistake? What can you do to prevent similar mistakes in the future and what improvements could you make? Then implement those improvements.
