Introduction
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.
