Abstract

A system and method for testing a telecommunication system, such as a voice messaging system (VMS) are provided. The system includes a processor for controlling the execution of test script commands used to direct testing of the telecommunication system, and a storage device is provided in communication with the processor for storing the test script commands. A directory in communication with the processor includes at least one service testing application associated with the telecommunication system and developed as a dynamic linked library (DLL). Contained within the service testing application are executable functions associated with the test script commands. A command engine in communication with the processor, storage device, and directory is operable to read the test script commands, scan the directory for the associated executable functions, and execute the associated executable functions. The system further includes a telecommunication interface in communication with the processor and the telecommunication system for generating test signals for receipt by the telecommunication system based on the test script commands and the associated executable functions.

Claims

1. A method of testing a telecommunication system, comprising:

reading a test script command;

scanning a directory for an executable function associated with the test script command, wherein the executable function is contained within a service testing application associated with the telecommunication system and developed as a dynamic linked library (DLL); and

executing the associated executable function in order to generate a test signal for receipt by the telecommunication system.

2. The method of claim 1, wherein the telecommunication system includes a voice messaging system (VMS).

3. The method of claim 1, further comprising scanning the directory for a syntax checking function.

4. The method of claim 3, further comprising passing a test parameter from the test script command to the syntax checking function.

5. The method of claim 1, further comprising detecting a response signal produced by the telecommunication system.

6. The method of claim 5, further comprising evaluating the response signal to assess the operation of the telecommunication system.

7. The method of claim 1, further comprising adding a test script command by adding at least one function to the service application.

8. The method of claim 1, wherein generating a test signal includes generating a DTMF signal.

9. The method of claim 1, wherein generating a test signal includes generating a voice signal.

10. A system for testing a telecommunication system, comprising:

a processor for controlling the execution of test script commands used to direct testing of the telecommunication system;

a storage device in communication with the processor for storing the test script commands;

a directory in communication with the processor, the directory having at least one service testing application associated with the telecommunication system and developed as a dynamic linked library (DLL), the at least one service testing application containing executable functions associated with the test script commands;

a command engine in communication with the processor, storage device, and directory for reading the test script commands, scanning the directory for the associated executable functions, and executing the associated executable functions; and

a telecommunication interface in communication with the processor and the telecommunication system to generate test signals for receipt by the telecommunication system based on the test script commands and the associated executable functions.

11. The system of claim 10, wherein the telecommunication system includes a voice messaging system (VMS).

12. The system of claim 10, wherein the storage device is further operable to store test parameters for the test script commands.

13. The system of claim 12, wherein the at least one service testing application further includes syntax checking functions operable to check the syntax of the test parameters.

14. The system of claim 10, wherein the telecommunication interface is further operable to detect a response signal produced by the telecommunication system.

15. The system of claim 10, wherein the processor is further operable to evaluate the response signal.

16. The system of claim 10, wherein the test signals comprise DTMF signals.

17. The system of claim 10, wherein the test signals comprise voice signals.
