Verifying dynamically generated operations on a data store includes carrying out setup actions for access to the data store, the setup actions being based at least in part on a request for which the dynamically generated operations will be generated. The carrying out of setup actions includes permissions being set for portions of the data store to establish a restricted portion of the data store and an unrestricted portion of the data store, as well as using one or more additional techniques to check whether any unexpected changes were made to the unrestricted portion or to lock access to parts of the unrestricted portion. After the dynamically generated operations are performed, a verification is made that no unexpected work was performed by the dynamically generated operations. If unexpected work was performed then the operations are determined to be not correct for the request.
