What is software regression?

regression software is a mistake in software programming that causes software to retreat efficiently in one or more areas. There are two main types of software regression: functional and non -functional. Functional means that the program works at the right speed, but one or more functions do not work, while non -functional means that all functions work, but the speed will decrease dramatically. An event like upgrading is usually the cause of regression. Regression testing checks the software to ensure that no regression does not occur. If this happens, the program will continue to run full speed, so the user will first notice regression. There are some features that no longer work. For example, if a program can search for files, this feature may no longer work. This can affect the functions of accessories - those that are unusually used - or the main functina program.

The malfunction of software regression is more dangerous and easier to notice, even if all functions still work. In thisThe manifestation, regression causes the program to run slower or the output of the program will be significantly smaller. Lack of speed means that the program can also be vulnerable to harmful coding and attacks, which gives the program and a computer that is endangered by hacking. Speed ​​can be so slow that it can be impossible to use the program.

There will be software regression for the so -called event. This event changes software coding and represents these mistakes, either deliberately - which is rare - or unintentionally. The developer can try to fix an error or update the version, but incorrectly represents a code that adjusts the program. The most typical event is upgrading because it directly affects the program coding. Other events include version changes or configuration.

To alleviate chances to software regression, regression testing is usually used. This type of testing looks at a new program and compares itwith all old versions of the program. It then launches the test programming to see if there is any sign of regression and to ensure that all encoding is functional. Any signs of regulated or non -functional code will be brought back to the developer or user and report what has retreated or where regression is found.
