Abstract

A system for testing branch execution and state transition logic in session initiation protocol application modular components. A test harness constructs, sends, and initializes an artificial session initiation protocol runtime environment in order to test session initiation protocol application modular components. The artificial session initiation protocol runtime environment simulates session initiation protocol messages and a determines whether an appropriate session initiation protocol event occurs. Subsequent to determining whether the appropriate session initiation protocol event occurs in response to the simulated session initiation protocol messages, a report of the test results is generated.

Claims

1. A computer implemented method for testing branch execution and state transition logic in session initiation protocol application modular components, the method comprising:

sending an artificial session initiation protocol runtime environment to a session initiation protocol application to test the session initiation protocol application modular components;

initializing the artificial session initiation protocol runtime environment;

simulating a session initiation protocol message; and

determining whether an appropriate session initiation protocol event occurs in response to simulating the session initiation protocol message.

2. The computer implemented method of claim 1, further comprising:

responsive to determining whether an appropriate session initiation protocol event occurs in response to simulating the session initiation protocol message, generating a test result report.

3. The computer implemented method of claim 1, wherein the sending, initializing, simulating, and determining steps are performed in a session initiation protocol server.

4. The computer implemented method of claim 1, wherein the sending, initializing, simulating, and determining steps are performed by a test harness.

5. The computer implemented method of claim 4, wherein the session initiation protocol application modular components load the artificial session initiation protocol runtime environment and send responses to the test harness.

6. The computer implemented method of claim 5, wherein the test harness analyzes the responses.

7. The computer implemented method of claim 5, wherein the responses comprise at least one of a test success and a test failure.

8. The computer implemented method of claim 1, wherein the artificial session initiation protocol runtime environment is created by a session initiation protocol application developer.

9. The computer implemented method of claim 1, wherein the appropriate session initiation protocol event comprises at least one of a particular session initiation protocol application state and a particular session initiation protocol application transition handler.

10. A data processing system for testing branches of execution and state transition logic in session initiation protocol application modular components, comprising:

a bus system;

a storage device connected to the bus system, wherein the storage device includes a set of instructions; and

a processing unit connected to the bus system, wherein the processing unit executes the set of instructions to send an artificial session initiation protocol runtime environment to a session initiation protocol application to test the session initiation protocol application modular components, initialize the artificial session initiation protocol runtime environment, simulate a session initiation protocol message, and determine whether an appropriate session initiation protocol event occurs in response to simulating the session initiation protocol message.

11. The data processing system of claim 10, wherein the sending, initializing, simulating, and determining steps are performed in a session initiation protocol server.

12. The data processing system of claim 10, wherein the sending, initializing, simulating, and determining steps are performed by a test harness.
