Ad hoc testing

Ad hoc testing is a commonly used term for planned software testing that is performed without initial test case documentation; however, ad hoc testing can also be applied to other scientific research and quality control efforts. Ad hoc tests are useful for adding additional confidence to a resulting product or process, as well as quickly spotting important defects or inefficiencies, but they have some disadvantages, such as having inherent uncertainties in their performance and not being as useful without proper documentation post-execution and -completion. Occasionally, ad hoc testing is compared to exploratory testing as being less rigorous, though others argue that ad hoc testing still has value as "improvised testing that deals well with verifying a specific subject."
