Running It Thru Automated Testing Software
Companies who buy softwares let it run through Automated Testing Software because they have to let it be tested with their own policies and their own scenarios and limitations so they too also know the limitations of the software that they bought and in this way they will also determine the capabilities of the software. The test should be able to go through all the modules propoosed by the company where they have gotten the software. In actuality automated testing can be mixed with manual testing. And it actually works better that way because the users can actually test what will happen when they do it in a certain way.
