Three Reasons Performance Testing Is Done Before An Application Is Released

You have probably heard about performance testing and wonder why it is a necessary step in the software development process. Performance testing is done in order to determine the success or failure of an application. Three specific reasons a program undergoes performance testing is to assess how well the software works, estimate how much profit loss or gain will occur upon release and figure out whether the program can handle any future growth.

Assessing How Well the Application Works

First and foremost, performance testing is done in order to assess how well an application is working. Testers will look for bugs that may cause problems with functionality and usability. Some examples of bugs that testers will look for are:

*Errors that may threaten the stability of the application.
*Problems that cause specific functions not to be successfully completed.
*Mistakes made in the configuration of the application that will cause slowness or lagging.
*Whether or not all commands and controls work properly.
*Issues with accessibility that may hinder disabled persons from successfully interacting with and using the application.
*Complications that cause the application to freeze or quit unexpectedly.
*Problems with incompatibility.

To do this, the program will be subjected to a variety of tests, like load tests, stress tests, spike tests, isolation tests and configuration tests. If any bugs are found, they are reported to the necessary parties, such as project managers or the developers themselves.

Estimate Gains or Losses

Based on the test results, project managers and developers will have the ability to make estimations concerning how much profits will be gained or lost upon release. If it is decided that there are problems that will cause profit losses, these problems are addressed, and the application is then retested.

Figure Out How Well the Program Will Handle Future Growth

Finally, testers and developers will work together in order to figure out how well the program will handle future growth. If it has been decided that the software will not handle growing in the future, changes will be made to facilitate expansion. While this may cause the time of release to be stalled, developers are willing to make the provisions necessary for growth and expansion because they know that will allow for further profits to be made as technology changes.

When all performance testing is completed, the release date is set because it is at this time the developers and/or project managers are confident that the software will work as designed. The software is released to the masses to be used on that specific date, and users are encouraged to report any bugs that have been missed by the testers.
