9. A system comprising: a processor; and a computer-readable storage medium having instructions stored which, when executed by the processor, cause the processor to perform operations comprising: converting a call flow into a context free grammar notation; converting the context free grammar notation into a finite state machine; generating test dialogs associated with the call flow according to paths through the finite state machine; extracting key data from a dialog call detail record from a dialog in the test dialogs; transmitting, to the finite state machine, the key data; and determining, based on the key data being accepted by the finite state machine, that the dialog is a valid dialog for the call flow.
