People, familiar with software development and web site testing, desktop testing and mobile application testing, know that there are errors in software products that are often called software bugs.

Errors are in every application. The task of test engineers is to find them performing manual and automated testing and report to the developers, who will correct them. Special test management and error tracking tools are used in order to streamline and simplify communication process between software developers, testers, managers and other project parties.

As a Rule, Errors in Applications Happen Because of Mistakes:

  • of the program designers;
  • of the programmers, who write the code;
  • of the compilers; it must be admitted that compilers make mistakes much more rarely than people.

Existence of various defects in software is a natural side effect of designing software and writing code.

If test engineers find various defects in course of functional testing, security testing, performance testing and so on, it does not necessarily mean that the developers are incompetent or irresponsible. Nowadays software products are so complex that it is impossible to design and code them without making software bugs.

There are many types of software bugs, they can be classified by severity, priority and other attributes. In general, an error appears when the system does something that it mustn’t do or does not do something that it must do.
