Defects & Failures
It is important to remember that not all coding errors result in software defects. In other words, one ordinary source of expensive defects are the result of requirements gaps. For example testability, scalability, maintainability, usability, performance, and security.
Testing is the process of identifying defects, where a defect is any difference between actual and suppose results. “A mistake in coding is referred to as Error. Moreover, the defect consider by the development team is a Bug, the build does not meet the requirements then it is Failure.
For instance, defects in dead code will never result in failures. However, a defect can turn into a failure and may result in failure when the environment changes.
Defects and failures basically arise from:
- First things first, if there is an error in the specification, design, and implementation of the software and system
- Secondly, defects may arise if there are errors in the use of the system
- After that, environmental conditions often lead to defects.
- In addition, if there is some or other kind of intentional damage
- Last but not the least, the potential consequences of earlier errors turn out to be defects.
