Each reapository will tell you what you are downloading but for testing purposes, you need to create a lab for yourself. No one, other than yourself, has the software, nor the configuration and knowledge of how you do business than youself. That is why, when downloading patches and av, large corporations and government agencies will first download the software to their internal labs where they have different computers set up with the different environments for testing. After rigourous testing, for a period of time, if all goes well, then the patches and av is distributed to the working environment. I would not want to be the one to send something out to the working environment without first testing it and wind up bringing down, say, an major sql database. I know this is not the answer you wanted, but, it is the right answer.
