What is software bug
An error, flaw, failure, or fault in a computer programme or system that causes it to generate an inaccurate or unexpected output or to behave in unanticipated ways is referred to as a software bug. Software bugs can also be referred to as software glitches.
In most cases, errors can be rectified by just updating the software. On the other hand, a software defect might occasionally result in the loss of data or security risks.
In most cases, the user is not to blame when a piece of software contains a problem.
On the other hand, users can occasionally be held accountable for failing to disclose a defect in the correct manner or for failing to follow instructions on how to prevent or work around the bug.
There is a wide variety of coding errors that can be found in software, and numerous taxonomies have been proposed to organise them. The following are some examples of frequent types of software bugs:
Errors in syntax occur when the code is not formed correctly or contains invalid characters. Syntax errors are the most common type of programming error. Logic errors are errors that occur when the code does not behave in the way that it is intended to behave.
Errors that occur during runtime are known as "runtime errors," and they occur when the programme is being executed. Memory leaks are mistakes that occur when a software does not handle memory in an appropriate manner, which can result in memory being wasted or not being sufficient.
Errors known as buffer overflows occur when a programme writes data over the capacity of a buffer, which ultimately results in corrupted data. Vulnerabilities in computer security are flaws in software or hardware that allow unauthorized users to gain access to confidential information or computer networks.
Finding and fixing software defects can be accomplished with the help of a wide variety of tools and approaches.
The following are examples of common tools:
Debuggers are a type of software that enables programmers to step through code and analyse data while it is being executed. Tools for static analysis are those that examine code without actually running it, searching for potential flaws in the process.
The term "unit testing" refers to a testing method in which discrete parts of software are examined to determine whether or not they perform as anticipated. Integration testing is a testing method in which several separate units of code are merged and tested together to ensure that they perform as intended when used in conjunction with one another.
Fuzz testing is a technique that involves generating inputs at random and then feeding them into a programme in an effort to cause the programme to crash.
Bugs are a normal part of the process of developing software, despite the fact that they can be extremely annoying. If you are able to gain a grasp of what software problems are and how to address them, you will be able to make your development process more effective and efficient.
Quality Assurance helps to fix an error/bug prior implementation of the software. Testers detect all the major and minor bugs that occur in the process of software testing and try to make the software application error free.
Software Testers have many questions after they find any error/bug from the application. The most common question arises here is that "What should be done after finding any bug from the application under test?" Quality assurance training include every necessary steps required to follow after determining software bug from the application under test.
Following steps are to be followed once the software bug is been detected:
Tester should communicate with the development team about the bug founded.
Prior reporting any bug to designer or developer, make sure that the bug is properly documented with the details like the number of occurrence of the bug, expected result, and so on.
Prepare a bug report that is accurate and covers entire details of the root of bug, its effect and solution.
A bug report thus prepared should be presented to the developer so that the exact reason of failure is determined.
On the basis of a bug report prepared, developer can know the problem faced by the end user and resolves it accurately.
Bug must be divided into different categories including Functional, Business, GUI, Validator error, and many more.
This will help to sort bugs into proper management.
The thumb rule for any tester is that they should be very much confident about the bug reporting. No duplicate bug, which means, the error which is already logged; should be added or submitted. Duplicate bug entry will create unnecessary work load in the process of bug management.
A software bug report can contain following information that is useful to developer:
Title: It helps to identify bug in a one line or statement description.
Description: It covers bug description along with the procedure to reproduce, expected result, example and actual result of system under test.
Status: This field indicated the actual status of the bug in the bug life cycle. Valid status is: Assigned, New, Resolved, Verified, and Reopened.
Browser: It shows on which particular browser version the issue occurred.
Severity: It describes about the impact of the issue. The different types of severity:
- Critical: Application is losing the data and is crashing.
- Major: Major function under testing is not working.
- Blocker: Further testing cannot be done unless this issue is fixed.
- Trivial: User Interface issues.
Priority: It indicates the priority of the bug. Whether the error occurred must be resolved on urgent basis or it’s less in priority; this point must be considered here. Starting from P1 to P5, priorities can be set. P1 means highest priority of resolving the issue. P5 means No urgency of fixing the issue.
In short a bug report is the medium of communication between the project manager, developer, leader and tester. Thus a quality bug report must be prepared containing all the bugs in the system.
Learn several methods of software testing to detect exact software bug in the application/product under test. QA manual and automation testing are the basic methods of software testing. QA software testing training is the essential part for learning necessary testing methods, and implement techniques in real application. Software quality assurance courses cover every module of testing and QA testing curriculum is designed in such a manner that every new method is covered in it.
