Bugzilla is another important bug tracking tool, which is most widely used by many organizations to track the bugs. Bugzilla is an open-source tool, which is used to help the customer, and the client to maintain the track of the bugs. It is also used as a test management tool because, in this, we can easily link other test case management tools such as ALM, quality Centre, etc. It is an open-source tool which is used to track the issues and web-based project management tool.
It is a web-based bug tracking system, and it is also an open-source tool. MantisBT is used to follow the software defects. It is executed in the PHP programing language. The backlog is widely used to manage the IT projects and track the bugs. It is mainly built for the development team for reporting the bugs with the complete details of the issues, comments.

Software Testing. Manual Testing Automation Testing. Functional Testing Non-Functional Testing. White Box vs. Software Testing Interview. Next Topic Regression Testing. Reinforcement Learning. R Programming. React Native. It should be retrievable at a later stage as well. If the system does not save the data or throws an error while saving, it can be considered a functional defect.
A logical error is mainly attributed to the code logic. The logic that was written by the developer may not function as expected leading to incorrect output. A classic example of this would be division by 0 or assigning the value to a wrong variable, or any other such mistake at the coding level. These logical errors can be easily avoided by doing peer reviews and code walk-throughs with the team. As the name suggests, these bugs arise for the calculation or formulae mistakes at the time of coding.
It can also be caused by passing the wrong parameter to the functions. Some other common reasons for a calculation error include choosing the wrong algorithm, mismatch in datatype, incorrect data values flowing from another system, or even hardcoding some values in the code. Errors caused by incorrect or missing validation messages are referred to as validation message errors. For example, when entering the wrong data or format, like in a number field age you enter characters like name, it should show an appropriate error message.
Likewise, whenever you want to save some data, a save confirmation or save failure message should be displayed. In all such cases, both positive and negative message pop-ups or message banners are checked. If they are not displayed, then it is considered an error. Cosmetic errors are those that do not impact the application or its functionality directly.
They are also minor issues that are fixed and implemented with the least priority. Some examples of cosmetic errors are spelling mistakes, alignment issues, color variations, and more.
Workflow errors are also called navigation errors. As the name suggests, they refer to navigation issues when traveling back and forth through the application. Any mismatch in the expected and actual page is considered a workflow error. Integration error refers to errors arising out of data mismatch or others during the interaction between multiple systems and modules. These errors can be identified only during integration testing.
In most cases, these integration errors are caused by how the data from one module is consumed by the other module, or sometimes the data may get altered in the system flow, or there could be a data-type mismatch, etc. Another common error usually found during rigorous and continuous testing is related to memory leaks.
In such cases, the application performance starts deteriorating drastically after a certain period. This is generally due to the continuous use of memory without releasing them after use. Memory leaks are very difficult to find or fix and the only way is to ensure proper coding standards and best practices are followed at the time of coding.
App Crash is a very priority issue that needs to be resolved at the earliest. It is clear from the name that in such cases the app abruptly closes and all the data is lost. This can be very annoying for the end customers. The crash can be due to several reasons including API call failure, page time out, upstream or downstream system down, or others.
In the internet world today, security is of utmost importance. Security bugs are very critical. They can be related to the safety of the user data, masking of user data and preferences, financial or health data, security based on privileges like admin pages being accessible only to app admins , and more. These issues if found in production can be detrimental to the application itself as the customers would lose trust in the system. They are invariably the discussion point between a developer and a tester.
Let us try to understand these terms better. The severity of a bug is the impact that the bug has on the business from a testing point of view. The priority of the bug on the other hand is fixed by the developers, based on how soon they want to fix the issue and merge with production code. Explaining Bug Life Cycle Another important term associated with a software bug is the lifecycle.
A bug life cycle refers to the different stages a software bug goes through. The different stages of a bug are:. When a defect or bug is raised by a tester it will be in a new status. Once the developers check, verify, and accept the defect only then it will be moved to the next stage. Once the developers accept the defect it is moved to the assigned state and is also assigned to a developer for fixing. Sometimes a defect raised by the tester would have been raised by someone else previously or a fix for one defect would be applicable for this defect as well, in such cases the developer will mark this new defect as the duplicate of the old one.
Some defects may not be accepted by the developers for various reasons like it may be the expected behavior, it may have already been fixed, or any other reason. These defects are marked as rejected and are not included in any defect metrics. Some defects may be considered as low priority or they may be fixed with the next module release. These defects are deferred to the next cycle or release. Once the defect is fixed by the developer in the development environment, it is marked as fixed.
The code fix for the defect gets moved to the test environment in the next cycle. Once the code fix for the defect is available in the test environment, it is marked as ready to test. Once a new build is available for testing, a tester would ideally filter out the ready to test defects, and do a retest.
When a tester retest a defect, if the defect is not fixed as expected or if it is only partially fixed, the tester would mark it as re-opened with suitable comments on what needs to be further fixed.
During the defect retesting, if the defect is completely fixed, the tester would mark it as verified and closed. This would be the end of the defect cycle for that particular defect. Why Does Software Have Bugs?
Programming errors are the most reasonable reason for the bugs in the software. Codes are developed by humans. And as humans, coders are supposed to make mistakes. There are many bugs that are introduced due to programming errors that might be because of wrong coding of the functionality, syntax errors, etc.
They could even be minor or we can say very clumsy errors that may result in big software flaws. Programming errors can be easily found, but sometimes these tiny errors can be very irritating and time-consuming. Miscommunication Miscommunication is indeed the reason behind many flaws and misunderstandings in our day-to-day lives.
They play no fewer roles in software engineering. Miscommunication is one of the main reasons behind software defects. Usually, a missing command is solved by a developer easily. In an online ludo product, if you roll your dice after choosing a color, it is a sequential flow error. Each type of software has its unique quality requirements, including how it should work if used.
A functionality error can occur whenever a software function fails to comply as expected. As an instance, you might recognize this as a functionality error if the minimize button on software closes the program. They are one of the most common software bugs. Allowing the use of special characters in the Name field can be an example of this error. In a banking world where information is crucial, data duplication errors are a point of no return.
A bank should have a unique data page for a specific individual. Suppose you have set your password length to 15 on your Sign Up page. But, your testers can log in using a password of character length This is a boundary value error. Security is the most crucial bit of your application product.
No user should penetrate your security system through illegal hacking. One way to check whether your website is secure or not is through security testing.
Software is only as good as the hardware capabilities of the devices it is intended to use. If it has hardware compatibility issues in devices, then the bug is known as a hardware defect. Software applications should always be user friendly. No matter which device you use it on, its user display functionalities should be compatible.
Communication Errors can lead to command errors. Sometimes, there is a lack of communication between clients and developers in the design phase. So, the developers may develop a software bit differently than it is intended to. This is known as a communication error. Errors can arise when users are using the software, and they need to be planned carefully. To solve the problems, it is essential to include error messages that users have to take. Usability software errors make software difficult to use and also affect the software experience of a user.
Examples of usability errors include a content interface that is hard to search or access and an unnecessarily complicated signup process. Deficiencies in performance are related to speed, stability, response time, and resource consumption by software. Identification of errors, classification, documentation, and deletion are all part of Quality Management activities.
Prevention, however, is more vital than recovery. At any point in time in the Software Development Life Cycle, the core issue of Software Quality Assurance is defining inspection and testing processes. The goal is to spot errors as quickly as possible. Therefore, early detection of software errors is essential.
