Abstract

Systems and methods can use a testing framework for testing an event processing system. The testing framework operates to send a stream of input events for an event processing system, wherein each said input event is associated with a timestamp that is based on a system time, and wherein said event processing system processes the stream of input events in a batch mode with one or more sliding cycles. Furthermore, the testing framework can determine a base time for an event window in the system time, wherein said event window includes one or more input events in a sliding cycle that corresponds to a plurality of expected output events associated with a shared timestamp, and applies the event window on the stream of input events that are sent to the event processing system.

Claims

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

sending a stream of input events for an event processing system, wherein each said input event is associated with a timestamp that is based on a system time, and wherein said event processing system processes the stream of input events in a batch mode with one or more sliding cycles;

determining a base time for an event window in the system time, wherein said event window includes one or more input events in a sliding cycle that corresponds to a plurality of expected output events associated with a shared timestamp; and

applying the event window on the stream of input events that are sent to the event processing system.

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 the base time in the system time for the event window to be a sliding point for the sliding cycle.

4. The method of claim 3, further comprising:

using an output time for a first assert as the sliding point in the system time for the event window.

5. The method of claim 4, further comprising:

allowing any insert event to be able to satisfy one or more verification conditions associated with the first assert.

6. The method of claim 4, further comprising:

using the event window, which starts from the sliding point in the system time, to verify a second assert.

7. The method of claim 4, further comprising:

using the shared timestamp to verify whether a plurality of actual output events received from an event processing system matches said plurality of expected output events.

8. The method of claim 7, further comprising:

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

9. The method of claim 7, 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.

10. The method of claim 9, further comprising:

applying a tolerance on the shared timestamp.

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

send a stream of input events for an event processing system, wherein each said input event is associated with a timestamp that is based on a system time, and wherein said event processing system processes the stream of input events in a batch mode with one or more sliding cycles;

determine a base time for an event window in the system time, wherein said event window includes one or more input events in a sliding cycle that corresponds to a plurality of expected output events associated with a shared timestamp; and

apply the event window on the stream of input events that are sent to the event processing system.

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:

the base time in the system time for the event window is a sliding point for the sliding cycle.

14. The system according to claim 13, wherein:

the testing framework uses an output time for a first assert as the sliding point in the system time for the event window.

15. The system according to claim 14, wherein:

the testing framework allows any insert event to be able to satisfy one or more verification conditions associated with the first assert.

16. The system according to claim 14, wherein:

the testing framework uses the event window, which starts from the sliding point in the system time, to verify a second assert.

17. The system according to claim 14, wherein:

the testing framework uses the shared timestamp to verify whether a plurality of actual output events received from an event processing system matches said plurality of expected output events.

18. The system according to claim 17, wherein:

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

19. The system according to claim 17, wherein:

the testing framework determines 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.

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

sending a stream of input events for an event processing system, wherein each said input event is associated with a timestamp that is based on a system time, and wherein said event processing system processes the stream of input events in a batch mode with one or more sliding cycles;

determining a base time for an event window in the system time, wherein said event window includes one or more input events in a sliding cycle that corresponds to a plurality of expected output events associated with a shared timestamp; and

applying the event window on the stream of input events that are sent to the event processing system.
