Bug is an error, default, problem in a software application or a system that causes it to work incorrectly or produce invalid or unexpected input. Bugs mostly occur because people make mistakes in the source code or its design or due to the necessity to develop a software program under tight deadlines.
We should not confuse the bugs (errors, defects, etc.) with the so–called features of an app or a system. Under this definition, we may understand all the features and functionality which have not rather been implemented in software but they should have been available in it to make it more successful. Testing software services are helpful to ensure superior quality and maximum performance of IT products by fixing all the bugs in them. Definitely, well-planned projects with clear objectives will never have questionable features since all the functionality is always discussed and determined in advance before the development process starts. This especially concerns customized projects. In this case, all the program’s features or functions are determined by the customer himself.
Classification of Software Bugs
Software bugs can be classified in various ways. By severity wise they can be:
Trivial: A common defect which is very easy to detect. As a rule, it does not affect the functionality of the app under test. These defects usually come in the form of design or cosmetic errors.
Minor: A defect that does not cause much harm to major functionality or features of the program but they produce more adverse impact than the previous counterparts.
Major: This type of defect causes the app to departure from its requirements specification or not to carry out a required feature.
Fatal: These are the most severe defects, also called as showstoppers. They often do not allow to run further testing. They can appear in many different ways and cause permanent failure of the application or buttons to be missing for a certain search.
It is easy to ensure the defect-free performance of your software by having it regularly tested at a properly equipped lab. Resorting to performance testing service you will be able to get rid of all functional problems in your application.
So, How to Protect the Program From Software Bugs?
There are different bug tracking systems which keep track of all reported defects in software development projects. These IT products are often used by software quality assurance companies to simplify bug management, make it more consistent and focus harder on identifying more issues.
