Abstract

A test framework for testing peer-to-peer applications allocates a test case manager and a plurality of distributed test units for each test case, which has a sequence of actions each to be performed by one of the test units. To enable the test units to perform the test case actions, the test case manager loads dynamic link library files (DDLs) containing the test case to each test unit, and creates on each test unit a test object that can be remotely activated using an object-remoting framework. To execute the test case, the test case manager goes through the sequence of test case actions. For each action, the test case manager calls the test object on a corresponding test unit to perform the action. In this way, the test case manager directs the test units to carry out the test case actions. The results of the test case actions are logged by the distributed test units and then collected for analysis and diagnosis.

Claims

1. A computer-readable medium having computer-executable instructions for performing steps for executing a test case for testing a peer-to-peer application, comprising:

receiving a set of dynamic link library files containing the test case, the test case having a sequence of a plurality of actions to be performed by multiple test units distributed on a network implementing a remoting framework for remote object activation;

loading the dynamic link library files containing the test case to the test units;

creating a remotely callable test object on each of the test units; and

going through the sequence of actions of the test case and for each action in the sequence;

identifying a test unit for performing said each action;

calling, via the remoting framework, the test object of said identified test unit to perform said each action.

2. A computer-readable medium as in claim 1, having further computer-executable instructions for performing the step of receiving a list identifying the test units participating in executing the test case.

3. A computer-readable medium having computer-executable instructions for performing steps for executing a test case for testing a peer-to-peer application, comprising:

allocating a test case manager and a plurality of test units for executing the test case, the test case manager and test units being on a network implementing a remoting framework for remote object activation;

providing a set of dynamic link library files containing the test case and data identifying the test units to the test case manager, the test case having a sequence of distributed actions to be performed by the test units;

loading, by the test case manager, the dynamic link library files containing the test case to the test units;

creating, by the test case manager, a remotely callable test object on each of the test units; and

controlling, by the test case manager, the execution of the sequence of actions of the test case, including;

identifying a test unit for performing each action;

calling, via the remoting framework, the test object of said identified test unit to perform said each action.

4. A computer-readable medium as in claim 3, having further computer-executable instructions for performing the step of presenting a user interface for a user to enter a selection of test cases for testing.

5. A computer-readable medium as in claim 3, having further computer-executable instructions for performing the step of transmitting, by each test unit, log information regarding actions performed by said each test unit to a log database.

6. A computer-readable medium as in claim 3, having further computer-executable instructions for performing the step of registering each of the test case manager and the test units with a machine manager.

7. A computer-readable medium as in claim 6, wherein the step of obtaining allocating includes requesting the machine manager to select the test case manager and the test units for executing the test case.

8. A computer-readable medium as in claim 3, having further computer-executable instructions for performing the step of presenting a user interface for a user to enter a selection of test cases to run.

9. A computer-readable medium as in claim 8, having further computer-executable instructions for performing the steps of:

receiving case selection criteria entered by a user through the user interface;

searching a test case database for test cases meeting the case selection criteria.

10. A method of executing a test case for testing a peer-to-peer application, comprising:

receiving a set of dynamic link library files containing the test case, the test case having a sequence of a plurality of actions to be performed by multiple test units distributed on a network implementing a remoting framework for remote object activation;

loading the dynamic link library files containing the test case to the test units;

creating a remotely callable test object on each of the test units; and

going through the sequence of actions of the test case and for each action in the sequence;

identify a test unit for performing said each action;

calling, via the remoting framework, the test object of said identified test unit to perform said each action.

11. A method as in claim 10, further including the step of receiving a list identifying the test units for use in executing the test case.

12. A method of executing a test case for testing a peer-to-peer application, comprising:
