Most software systems have installation procedures that are needed before they can be used for their main purpose.
Implementation testing is usually defined as testing which places a compiled version of code into the testing or pre-production environment, from which it may or may not progress into production.unclear reference to implementation testing,[non sequitur] This generally takes place outside of the software development environment to limit code corruption from other future or past releases (or from the use of the wrong version of dependencies such as shared libraries) which may reside on the development environment.unclear connection to implementation testing and software development environment,[non sequitur] The simplest installation approach is to run an install program, sometimes called package software.
A factor that can increase the organizational requirements of such an exercise is the need to synchronize the data in the test deployment environment with that in the live environment with minimum disruption to live operation.
This type of implementation may include testing of the processes which take place during the installation or upgrade of a multi-tier application.
This type of testing is commonly compared to a dress rehearsal or may even be called a "dry run".
