Abstract

Methods, systems and computer program products for performing multi-location execution of tests between or among multi-sided test components in a wireless environment are described. Multiple flows are initiated substantially simultaneously and concurrently executed. A graphical representation of a multi-flow test is created that permits synchronization of the flows among agents at multiple remote locations. The graphical representation is converted into a textual representation in an open communication standard format, and information regarding each flow involved in the test is ascertained. The flows are substantially simultaneously initiated and concurrently executed with synchronization and dynamic data exchange components.

Claims

1. A method of performing multi-location testing in a system having a test controller and at least a first flow at a first remote location and a second flow at a second remote location, comprising the steps of:

creating a graphical representation of a multi-flow test that synchronizes at least the first flow and the second flow among agents at multiple remote locations;

converting the graphical representation into a textual representation in an open communication standard format;

reading the textual representation to identify at least the first flow and an associated first remote location, the second flow and an associated second remote location, resources required to execute the flows, and the remote locations of the agents that control the resources required to execute the flows;

sending to at least a first test session server at the first remote location and a second test session server at the second remote location, descriptions of the respective sequences of tests comprising the first flow and the second flow in an open communications standard format;

substantially simultaneously initiating at least the first flow and the second flow;

synchronizing at least the first flow and the second flow for concurrent execution; and

returning test results upon completion of at least the first flow and the second flow.

2. The method of claim 1, wherein the synchronizing step further comprises sending control messages between or among multi-sided test components comprising at least the first flow and the second flow, respectively, the control messages permitting the flows to implicitly exchange timing synchronization information and dynamically-generated data.

3. The method of claim 1, wherein at least the first flow and the second flow run independently from a master flow.

4. The method of claim 1, wherein the synchronizing step further comprises:

pausing execution in at least one of the first flow and the second flow;

sending, from the flow not paused, a synchronization signal to a sync server;

requesting, from the paused flow to the sync server, permission to resume execution;

upon receipt of the synchronization signal by the sync server, granting permission to the paused flow to resume execution; and

resuming execution of the paused flow.

5. The method of claim 1, wherein the system does not include a proprietary interface.

6. The method of claim 1, wherein an open common communication standard for data transfer is employed to effect synchronization of flows.

7. The method of claim 1, wherein the synchronizing step further comprises:

generating, in at least one of the first flow and the second flow, dynamic data;

posting, using at least one open common communication standard, the dynamic data to a dynamic content server to form posted dynamic data;

requesting, from at least one of the first flow and the second flow to the dynamic content server, the posted dynamic data; and

sending, from the dynamic content server, the posted dynamic data to the flow requesting the posted dynamic data.

8. A system for performing multi-location testing including at least a first flow at a first remote location and a second flow at a second remote location, comprising:

means for creating a graphical representation of a multi-flow test that synchronizes at least the first flow and the second flow among agents at multiple remote locations;

means for converting the graphical representation into a textual representation in an open communication standard format;

means for reading the textual representation to identify at least the first flow and an associated first remote location, the second flow and an associated second remote location, resources required to execute the flows, and the remote locations of the agents that control the resources required to execute the flows;

means for sending to at least a first test session server at the first remote location and a second test session server at the second remote location, descriptions of the respective sequences of tests comprising the first flow and the second flow in an open communications standard format;

means for substantially simultaneously initiating at least the first flow and the second flow;

means for synchronizing at least the first flow and the second flow for concurrent execution; and

means for returning test results upon completion of at least the first flow and the second flow.

9. The system of claim 8, wherein the synchronizing means further comprises means for sending control messages between or among multi-sided test components comprising at least the first flow and the second flow, respectively, the control messages permitting the flows to implicitly exchange timing synchronization information and dynamically-generated data.

10. The system of claim 8, wherein at least the first flow and the second flow run independently from a master flow.

11. The system of claim 8, wherein the synchronizing means further comprises:

means for pausing execution in at least one of the first flow and the second flow;

means for sending, from the flow not paused, a synchronization signal to a sync server;

means for requesting, from the paused flow to the sync server, permission to resume execution;

upon receipt of the synchronization signal by the sync server, granting permission to the paused flow to resume execution; and

means for resuming execution of the paused flow.

12. The system of claim 8, wherein the system does not include a proprietary interface.

13. The system of claim 8, wherein an open common communication standard for data transfer is employed to effect synchronization of flows.

14. The system of claim 8, wherein the synchronizing means further comprises:

15.
