Abstract

A computer program product for command result verification is configured to receive a command and an expected result from a command line interface, execute the command, receive one or more result codes resulting from the execution of the command, determine whether the one or more result codes satisfy the expected result, and send a response to the command line interface in response to determining whether the one or more result codes satisfy the expected result.
