Abstract

Systems and methods can use a testing framework for testing an event processing system. The testing framework operates to send a plurality of input events in multiple event streams to an event processing system, wherein each said input event is associated with a timestamp. Also, the testing framework prescribes one or more expected output events that correspond to said plurality of input events in multiple event streams, wherein each said expected output event is associated with a timestamp. Furthermore, the testing framework can use said one or more expected output events to verify one or more actual output events that are received from the event processing system, wherein each said actual output event is associated with a timestamp.

Claims

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

sending a plurality of input events in multiple event streams to an event processing system, wherein each said input event is associated with a timestamp;

prescribing one or more expected output events that correspond to said plurality of input events in multiple event streams, wherein each said expected output event is associated with a timestamp; and

using said one or more expected output events to verify one or more actual output events that are received from the event processing system, wherein each said actual output event is associated with a timestamp.

2. The method of claim 1, further comprising:

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

3. The method of claim 2, further comprising:

using an attribute in an assert element in the XML file to indicate multiple event streams.

4. The method of claim 1, further comprising:

configuring said different event streams with separate connections, event channel, and threads.

5. The method of claim 1, further comprising:

applying a plurality of event windows on the different event streams, wherein each said event stream is applied with one said event window.

6. The method of claim 5, further comprising:

allowing said plurality of event windows to be in different types.

7. The method of claim 1, further comprising:

allowing the event processing system to use a query to correlate said plurality of input events in multiple event streams to generate said one or more actual output events.

8. The method of claim 1, further comprising:

allowing said plurality of event windows applied on multiple event streams to share a common base time.

9. The method of claim 8, further comprising:

using the time when the first assert statement is processed as the base time for an application timestamped event stream in a test.

10. The method of claim 8, further comprising:

using the time when the first assert statement is processed after a corresponding sliding point is obtained as the base time for a system timestamped event stream in a test.

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 plurality of input events in multiple event streams to an event processing system, wherein each said input event is associated with a timestamp;

prescribe one or more expected output events that correspond to said plurality of input events in multiple event streams, wherein each said expected output event is associated with a timestamp; and

use said one or more expected output events to verify one or more actual output events that are received from the event processing system, wherein each said actual output event is associated with a timestamp.

12. The system according to claim 11, wherein:

the testing framework operates to declare input data, output data, and at least one processing rule for a test in an XML file, and wherein the XML file is associated with an XML schema for testing the event processing system.

13. The system according to claim 12, wherein:

the testing framework operates to use an attribute in an assert element in the XML file to indicate multiple event streams.

14. The system according to claim 11, wherein:

the testing framework operates to configure said different event streams with separate connections, event channel, and threads.

15. The system according to claim 11, wherein:

the testing framework operates to apply a plurality of event windows on the different event streams, wherein each said event stream is applied with one said event window.

16. The system according to claim 15, wherein:

said plurality of event windows are in different types.

17. The system according to claim 11, wherein:

the testing framework allows the event processing system to use a query to correlate said plurality of input events in multiple event streams to generate said one or more actual output events.

18. The system according to claim 11, wherein:

the testing framework allows said plurality of event windows applied on multiple event streams to share a base time.

19. The system according to claim 18, wherein:

the testing framework uses the time when the first assert statement is processed as the base time for an application timestamped event stream in a test, and

the time when the first assert statement is processed after a corresponding sliding point is obtained as the base time for a system timestamped event stream in a test.

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 plurality of input events in multiple event streams to an event processing system, wherein each said input event is associated with a timestamp;

prescribing one or more expected output events that correspond to said plurality of input events in multiple event streams, wherein each said expected output event is associated with a timestamp; and

using said one or more expected output events to verify one or more actual output events that are received from the event processing system, wherein each said actual output event is associated with a timestamp.
