When do Defects Often Appear in Software Products?
It is of common knowledge that modern software products often are complex and sophisticated systems. It takes considerable time and resources to code them and to perform mobile testing, desktop testing or web site testing.
Many developers are usually involved in creation of such system and the process consists of many stages. Each time new parts of code are added, new functions and features are implemented.
A software testing company confirms that new defects often appear when changes in the code are made. It seems that everything must work fine and only the added features should be checked.
But in order to make the project efficient both the new functions and features and the ones that were ready and worked fine must be checked. Because any change in the code may have unexpected impact on various areas of the system.
This way errors appear in places that contained no defects before. Such errors are called regression defects. That is why each new build of the software product requiresregression testing.
So, one must check many times the same areas of a software product. In this case automated testing is very helpful. It increases effectiveness of the testing process and helps to create commercially viable qualitative software product.
