A software defects are flaws in a software product. In this case, it does not meet a software requirement based on requirement specifications. Likewise, the expectations of the end-users. In other words, a defect is a coding error, resulting in program malfunction, also incorrect or unexpected results. A defect is also called a software bug.
Software bugs are of many types. A virus is a bug, no matter what. But sometimes, it is essential to understand the nature, its implications, and the cause to process it better.
Types of Defects
Defects come in different types. Below are the type of software defects, so you can get to know them and understand them better.
Identifying defects is all part of software testing and development. It does not only mean identifying defects. It also include resolving and preventing these defects from recurring. This is what software quality assurance is all about.
The main goal of software testing is to find defects, resolve them,and prevent them from coming back. Detecting errors as early as possible is the primary concern of quality assurance. Doing this can reduce the cost of the project and may require less time to complete.
Interface defects mean the defects in the interaction of the software and the users. The system may suffer different kinds of interface testing in the forms of the complicated interface, unclear interface, or the platform based interface.
Arithmetic defects refer to errors made by the developer in arithmetic expressions. It also means the mistakes encountered in solving arithmetic expressions. Arithmetic defects are commonly made by programmers because of a lack of knowledge and work access. Another cause of arithmetic defects is code congestion. In other words, a programmer will not be able to monitor the code accurately.
Mistakes or errors in the style the code is written are called Syntax defects. Its focus is on insignificant mistake the developer commits while the code is being written. Syntax defects often occur when small symbols escape.
Logical defects are errors that occur in connection with code implementation. This type of defect happens when the programmer is unclear about the problem or has a different perspective on the issue. In other words, a logical error is connected with the software’s core.
Performance defects are the defects when the system or the software application is unable to meet the desired and the expected results. When the order or the software application does not fulfill the users’ requirements, then that is the performance defects. It also includes the response of the system with the varying load on the system.
Multi-threading means running or executing multiple tasks at the same time. Hence in the multi-threading process, there is the possibility of complex debugging. In multi-threading processes, sometimes there is a condition of the deadlock, and starvation is created that may lead to the system’s failure.
To Wind Up
Defects are caused by the developer in the development phase of the software. When a developer or programmer during the development phase makes some mistake, then that turns into bugs that are called defects. The developers’ mistakes cause them.
Software product defect shows that the software is ineffective and unable to meet criteria and requirements specified for the project. Therefore, the software application will not be able to function as it should and work as expected.
