Method and system for dynamic conditional interaction in a VoiceXML run-time simulation environment
View Patent ↗A method and system for testing voice applications, such as VoiceXML applications, is provided. The system provides a run-time simulation environment for voice applications that simulates and automates user interaction. A user simulation script is provided in a customized mark-up language. The voice application is processed to derive a nominal output of the voice application. The user simulation script is processed to generate a simulated output for the voice application corresponding to the nominal output. Conditional logic may be applied to the nominal output to generate a simulated input in response thereto. The user simulation script is specified in a customized mark-up language having a set of one or more conditional tags and an internal variable for the nominal output of the voice application.
1. A method for simulating a dynamic run-time user interaction with a voice application, said method comprising the steps of:
loading a user simulation script programmed to specify simulated voice interactions with the voice application;
deriving from the voice application a nominal output;
generating a simulated output for the voice application corresponding to the nominal output;
generating a first simulated input for the voice application corresponding to a first pre-determined user input to the voice application, if the nominal output satisfies a first condition; and
generating a second simulated input for the voice application corresponding to a second pre-determined user input to the voice application, if the nominal output satisfies a second condition different from the first condition.
2. The method of claim 1 ,
wherein the user simulation script is specified in a customized mark-up language, the customized mark-up language having a set of one or more conditional tags.
3. The method of claim 2 ,
wherein the customized mark-up language includes an internal variable for nominal output of the voice application.
4. The method of claim 3 , further comprising the steps of:
setting the internal variable to equal the nominal output of the voice application;
resolving a first conditional statement using a first conditional tag to generate the first simulated input if the internal variable equals a first nominal output of the voice application; and
resolving a second conditional statement using a second conditional tag to generate the second simulated input if the internal variable equals a second nominal output of the voice application.
