Operational_testing

A Tester uses a concrete or conceptual Product in order to determine either whether it works or to find out how well or in which manner it works. The Tester may have particular Unwanted_characteristics in mind that they are specifically looking for. The operational test may also be carried out under a particular set of Circumstances that are typically relevant to the functioning of the Product. Sun has (hopefully) already tested it for compliance. The Velcro hook and loop closure system has been tested under wet conditions and retains its holding power after 10,000 open and close functions. CNI INI Roe revisited the compound and tested it as a mosquito repellent.
