A technique for generating testcases includes receiving a new product specification for an application. A noun-verb pairing is performed on the new product specification. An attempt is made to locate a similar noun-verb pairing in a previous product specification for the application that corresponds to the new noun-verb pairing. In response to locating the similar noun-verb pairing in the previous product specification, a new testcase is generated by modifying an existing testcase that is associated with the similar noun-verb pairing in the previous product specification. In response to not locating the similar noun-verb pairing in the previous product specification, the fact that the new testcase was not generated is indicated.
