The importance of software testing

The importance of software testing

In almost all areas of human activity and production there is a need for evaluation and testing, and the same goes for software development as well. Software is a written set of codes and orders which can often be flawed, since human beings are not perfect and we occasionally make mistakes, no mater how hard we try not to. Since mistakes happen, people have invented different methods and principles that can help them to eliminate those problems, and testing software is one of those tools.

Same as wit any other area, testing software is important since it provides insight into bugs and errors that can be hidden within the program, either intentionally present there or not. Those intentional “mistakes” are especially dangerous, since they are basically that what we call viruses, spam and malware, and those malicious programs can cause severe problems to business users and even those who use computer on a personal level.

They perform code analysis, which can be dynamic and static, and they essentially try to answer on one simple question: does the program do what it is supposed to? Of course, some other elements are tested, but it all comes down to the fact that testing software tools and teams check if a code meets the requirements of the buyer. Testing is often an integral part of software development life cycle (SDLC), and can be divided into two basic principles – verification and validation. Both of these have the same idea behind them, and that is to evaluate and asses all aspects of a program and to investigate if there are any bugs or defects present.

Becoming a Software Testing Expert

Objective and independent software testing is very important in corporate programs, when a security breach often happens through applications and programs that hide some malicious intention within their source code. That is the reason why software that is business-oriented should be checked by professional testing software tools and with experts that have experience in the business. Several different steps of testing are present during the production of a program, and testing can be divided into unit testing, integration testing and functional testing. Unit testing is concerned with functionality of small parts and components of the complete program, while the other two perform tests on a higher level. All of them are important, since each targets different aspects of the program’s usability and therefore uses different parameters and explores different problems that can potentially arise. Also, different levels enable developers to easily find exact locations of the bug and to fix the problem without any significant loss in time or other resources.

Software is a very sensitive matter, and it should be tested as much as possible to make it run perfectly in all situations that can potentially happen in a lifetime of a program, and that is why the importance of software testing is very big.
