Abstract

To facilitate the testing of a testee network service such as a web service made available on the Internet, various embodiments of a network service test system are provided. In one embodiment, a testee network service is tested using a network service test environment. The network service test environment surrounds the testee network service. The network service test environment comprises at least one mock client that is in data communication with and interacts with the testee network service. The network service test environment also includes at least one mock support network service in data communication with the testee network service. The at least one mock support network service simulates a performance of an actual support network service while a data communication link exists between the actual support network service and the testee network service.

Claims

1. A network service test system, comprising:

a testee network service stored in a memory and executable by a processor;

a network service test environment surrounding the testee network service, the network service test environment comprising;

at least one mock client in data communication with and interacting with the testee network service; and

at least one mock support network service in data communication with the testee network service, the at least one mock support network service simulating a performance of an actual support network service while a data communication link exists between the actual support network service and the testee network service.

2. The network service test system of claim 1, further comprising a redirector in data communication with the testee network service and the at least one mock support network service, wherein a number of requests transmitted by the testee network service to the actual support network service are rerouted by the redirector to the at least one mock support network service.

3. The network service test system of claim 2, wherein the redirector routes a number of responses from the at least one mock support network service to the testee network service in response to the requests, respectively.

4. The network service test system of claim 1, further comprising a network service environment generation system that generates the at least one mock client and the at least one mock support network service.

5. The network service test system of claim 1, wherein the network service environment generation system that generates the at least one mock client and the at least one mock support network service, further comprises:

logic stored in the memory and executable by the processor that generates the at least one mock client from a mock client template; and

logic stored in the memory and executable by the processor that generates the at least one mock support network service from a mock support network service template.

6. The network service test system of claim 1, wherein the at least one mock support network service further comprises a lookup table that maps a number of requests expected from the testee network service to a corresponding number of responses.

7. The network service test system of claim 1, further comprising a number of test cases associated with the at least one mock client, wherein each of the test cases specifies a request that is to be transmitted to the testee network service and a response expected from the testee network service in reply to the request.

8. The network service test system of claim 7, wherein the number of test cases are grouped into a test suite.

9. A program embodied in a computer readable medium to facilitate network service testing, comprising:

code that generates a network service test environment that surrounds a testee network service, the network service test environment comprising;

at least one mock client that interacts with the testee network service; and

at least one mock support network service that interacts with the testee network service, wherein the at least one mock support network service simulates a performance of an actual support network service while a data communication link exists between the actual support network service and the testee network service.

10. The program embodied in the computer readable medium of claim 9, wherein the network service test environment further comprises code that redirects a number of requests transmitted to the actual support network service by the testee network service to the at least one mock support network service.

11. The program embodied in the computer readable medium of claim 10, wherein the network service test environment further comprises code that redirects a number of responses from the at least one mock support network service to the testee network service in response to the requests, respectively.

12. The program embodied in the computer readable medium of claim 9, wherein the code that generates the network service test environment that surrounds the testee network service, further comprises:

code that generates the at least one mock client from a mock client template; and

code that generates the at least one mock support network service from a mock support network service template.

13. The program embodied in the computer readable medium of claim 9, wherein the at least one mock support network service further comprises a lookup table that maps a number of requests expected from the testee network service to a corresponding number of responses.

14. The program embodied in the computer readable medium of claim 13, wherein the code that generates the network service test environment that surrounds the testee network service further comprises code that facilitates a user input of the requests and the responses.

15. The program embodied in the computer readable medium of claim 9, further comprising a number of test cases associated with the at least one mock client, wherein each of the test cases specifies a request that is to be transmitted to the testee network service and a response expected from the testee network service in reply to the request.

16. The program embodied in the computer readable medium of claim 15, wherein the number of test cases are grouped into a test suite.

17. The program embodied in the computer readable medium of claim 15, wherein the code that generates the network service test environment that surrounds the testee network service further comprises code that facilitates a user input of the test cases.

18. A method for network service testing, comprising the steps of:

executing a testee network service using at least one processor circuit;
