Abstract

The systems and methods described herein can be used to provide virtual service environments. In one embodiment, a virtual service model is generated by detecting one or more transactions, each of which includes a request sent from a requester to a software service and a response sent from the software service to the requester; storing information describing the detected transactions in a virtual service model, where the information describing each transaction includes information identifying a command included in the request and information identifying a response attribute included in the response; and generating information describing an unknown transaction, where the information describing the unknown transaction includes information identifying a first command and information identifying a first response attribute. The first command and the first response attribute are copies of a corresponding command and a corresponding response attribute associated with a corresponding one of the detected transactions.

Claims

1. A method comprising:

monitoring, using a processor device, transactions involving a particular software service;

detecting, during the monitoring, a particular transaction comprising an observed request of the particular software service and an observed response to the request from the particular software service;

identifying a time-sensitive attribute of the particular transaction; and

generating a virtual service model comprising transaction information describing the detected particular transaction, wherein the virtual service model models a response of the particular software service based on the time-sensitive attribute.

2. The method of claim 1, wherein the transaction information describes a plurality of transactions involving the particular software service.

3. The method of claim 1, wherein the time-sensitive attribute defines a delta time value between a first time value of the observed request and a second time value of the observed response.

4. The method of claim 3, wherein the first time value is a system clock time value corresponding to the observed request.

5. The method of claim 3, wherein the first time value is a system clock time value corresponding to the observed response.

6. The method of claim 3, wherein the second time value is a time value attribute of the observed request.

7. The method of claim 3, wherein the second time value is a time value attribute of the observed response.

8. The method of claim 3, wherein the first and second time values are captured during the monitoring.

9. The method of claim 3, wherein the second time value comprises a user-defined value.

10. The method of claim 3, wherein the second time value is a time value in a plurality of time values of the observed response and the time-sensitive attribute defines respective delta time values for each of the plurality of time values relative the first time value.

11. The method of claim 1, further comprising determining whether the observed response is a time-sensitive response.

12. The method of claim 11, wherein determining whether the observed response is a time-sensitive response comprises attempting to identify a time attribute in the observed response.

13. The method of claim 12, wherein a system clock value corresponding to the observed response is identified in the absence of a time attribute in the observed response.

14. The method of claim 1, wherein the time-sensitive attribute is an at least partially user-defined.

15. The method of claim 14, wherein the observed request comprises a time attribute in the request and a detected system clock value corresponding to the request and the time-sensitive attribute comprises a user definition that the time-sensitive attribute is dependent on one of the time attribute in the request and the detected system clock value.

16. A computer program product comprising a computer readable storage medium comprising computer readable program code embodied therewith, the computer readable program code comprising:

computer readable program code configured to monitor transactions involving a particular software service;

computer readable program code configured to detect, during the monitoring, a particular transaction comprising an observed request of the particular software service and an observed response to the request from the particular software service;

computer readable program code configured to identify a time-sensitive attribute of the particular transaction; and

computer readable program code configured to generate a virtual service model comprising transaction information describing the detected particular transaction, wherein the virtual service model models a response of the particular software service based on the time-sensitive attribute.

17. A system comprising:

a processor device;

a memory element; and

service model generator adapted to;

monitor transactions involving a particular software service;

detect, during the monitoring, a request of the particular software service;

detect, during the monitoring, a response by the particular software service to the request;

determine a time-sensitive attribute of the response relative to the request; and

generate a virtual service model of the particular software service based at least in part on the detected request, detected response, and time-sensitive attribute.

18. The system of claim 17, wherein the time-sensitive attribute defines a time delta between the detected request and the detected response.

19. The system of claim 18, wherein a particular observed transaction involving the particular software service comprises the detected request and the detected response and the system further comprises a request processing module adapted to:

receive, from a requesting software component, a request of the particular software service;

identify, from the virtual service model, that the particular request corresponds to the particular observed transaction;

return to the requesting software component a particular response to the received request, the particular response generated from the virtual service model and applying the time-sensitive attribute.

20. A method comprising:

receiving, from a requesting software component, a request of a particular service;

identifying a virtual service model corresponding to the particular service, the virtual service model modeling the particular service and adapted to model a time-sensitive response of a particular transaction of the particular service; and

using a processor device to return to the requesting software component a particular response to the received request generated from the virtual service model.

21. The method of claim 20, wherein returning the particular response comprises:

identifying that the received request substantially matches a particular request of the particular transaction;

identifying a time value of the received request; and

applying a time-sensitive value of the time-sensitive response to the time value of the received request to generate a time attribute of the returned request.

22. The method of claim 21, wherein the time value of the received request is a system clock value detected as corresponding with the receiving of the request.

23. The method of claim 21, wherein the time value is an attribute of the received request.

24. The method of claim 21, wherein the time-sensitive value is a time delta value between a time value corresponding to the particular request of the particular transaction and a time value corresponding to the time-sensitive response of the particular transaction.

25. The method of claim 20, wherein the request is received in a virtual service environment comprising one of a development, testing, load testing, integration testing, and training environment.

26. A computer program product comprising a computer readable storage medium comprising computer readable program code embodied therewith, the computer readable program code comprising:

computer readable program code configured to receive, from a requesting software component, a request of a particular service;

identify a virtual service model corresponding to the particular service, the virtual service model modeling the particular service and adapted to model a time-sensitive response of a particular transaction of the particular service; and

return to the requesting software component a particular response to the received request generated from the virtual service model.
