Abstract

Systems and methods can use a testing framework for testing an event processing system. The testing framework operates to apply a sliding window on a stream of input events that are sent to an event processing system, wherein said event processing system processes the stream of input events in a batch mode with one or more sliding cycles, and wherein said sliding window includes one or more input events in a sliding cycle that correspond to a plurality of expected output events. Furthermore, the testing framework can receive a plurality of actual output events at an end of said sliding cycle in the batch mode from the event processing system, and uses said one or more expected output events to verify said one or more actual output events.

Claims

1. A method for testing an event processing system, comprising:

applying a sliding window on a stream of input events that are sent to an event processing system, wherein said event processing system processes the stream of input events in a batch mode with one or more sliding cycles, and wherein said sliding window includes one or more input events in a sliding cycle that correspond to a plurality of expected output events;

receiving a plurality of actual output events at an end of said sliding cycle in the batch mode from the event processing system; and

using said one or more expected output events to verify said one or more actual output events.

2. The method of claim 1, further comprising:

declaring input data, output data, and a processing rule for a test in an XML file, wherein the XML file is associated with an XML schema that is designed for testing the event processing system.

3. The method of claim 1, further comprising:

allowing each said input event to be associated with a timestamp and said plurality of expected output events to be associated with a shared timestamp, and

allowing each said actual output event to be associated with a timestamp.

4. The method of claim 3, further comprising:

verifying whether the timestamp associated with each said actual output event matches the shared timestamp associated with said plurality of expected output events in the sliding window.

5. The method of claim 4, further comprising:

allowing said plurality of actual output events to be received from the event processing system in different orders.

6. The method of claim 4, further comprising:

determining that an assert fails when at least one timestamp associated with said plurality of actual output events does not match the shared timestamp associated with said plurality of expected output events in the sliding window.

7. The method of claim 6, further comprising:

applying a tolerance on the shared timestamp.

8. The method of claim 1, further comprising:

allowing the sliding window to be based on an application time, wherein the application time is used as an attribute in each said event.

9. The method of claim 1, further comprising:

associating a length and a frequency with the sliding window.

10. The method of claim 9, further comprising:

moving the sliding window periodically, after receivng one or more actual output events in a sliding cycle from the event processing system.

11. A system for testing an event processing system, comprising:

one or more microprocessors;

a testing framework, running on the one or more microprocessors, wherein the testing framework operates to

apply a sliding window on a stream of input events that are sent to an event processing system, wherein said event processing system processes the stream of input events in a batch mode with one or more sliding cycles, and wherein said sliding window includes one or more input events in a sliding cycle that correspond to a plurality of expected output events;

receive a plurality of actual output events at an end of said sliding cycle in the batch mode from the event processing system; and

use said one or more expected output events to verify said one or more actual output events.

12. The system according to claim 11, wherein:

the testing framework allows input data, output data, and a processing rule for a test to be declared in an XML file, wherein the XML file is associated with an XML schema that is designed for testing the event processing system.

13. The system according to claim 11, wherein:

each said input event is associated with a timestamp and said plurality of expected output events are associated with a shared timestamp, and

each said actual output event is associated with a timestamp.

14. The system according to claim 13, wherein:

the testing framework operates to verify whether the timestamp associated with each said actual output event matches the shared timestamp associated with said plurality of expected output events in the sliding window.

15. The system according to claim 14, wherein:

the testing framework allows said plurality of actual output events to be received from the event processing system in different orders.

16. The system according to claim 14, wherein:

the testing framework determines an assert fails when at least one timestamp associated with said plurality of actual output events does not match the shared timestamp associated with said plurality of expected output events in the sliding window.

17. The system according to claim 16, wherein:

the testing framework operates to apply a tolerance on the shared timestamp.

18. The system according to claim 14, wherein:

the testing framework allows the sliding window to be based on an application time, wherein the application time is used as an attribute in each said event.

19. The system according to claim 11, wherein:

the testing framework allows the sliding window to be associated with a length and a frequency, and the testing framework operates to move the sliding window periodically, after receivng one or more actual output events in a slidng cycle from the event processing system.

20. A non-transitory machine readable storage medium having instructions stored thereon that when executed cause a system to perform the steps comprising:

applying a sliding window on a stream of input events that are sent to an event processing system, wherein said event processing system processes the stream of input events in a batch mode with one or more sliding cycles, and wherein said sliding window includes one or more input events in a sliding cycle that correspond to a plurality of expected output events;

receiving a plurality of actual output events at an end of said sliding cycle in the batch mode from the event processing system; and

using said one or more expected output events to verify said one or more actual output events.
