What Is Parallel Testing?

           Parallel testing refers to the testing of the new application on a computer which has replaced the older version of the same application that was running on that particular computer. The reason why this testing is done is to ensure that the new version that has been installed is running correctly without any problems creating to the computer's hard disk or the processor. If there is any kind of problem found, the application will be terminated and you might have to uninstall it and reinstall it.

           This process should only be conducted if you are having doubts or uncertainties between the two versions of the application. Some people also conduct this test to copy the settings that they have changed on the old version so that it automatically applies to the new version as well.
