Abstract

End-to-end testing of applications across networks is enabled. To test the application and the infrastructure subsystems, an application server connected to the network contains an application under test. A response simulator is connected to the other end of the network. A test module is accessible to the application and to the simulator and contains a test message to be transmitted to the simulator, and an expected response message from the simulator. The application transmits each test message and compares a response message from the simulator to an expected response message. The simulator obtains the response to each test message from the test module.

Claims

1. A system for enabling end-to-end testing of applications across a network, comprising

an application server connected to the network and having an application to be tested,

a response simulator connected to the other end of the network,

a test module accessible to the application server and to the simulator and containing a test message to be transmitted to the simulator and an expected response message from the simulator corresponding to the test message,

a control module for controlling the application under test to transmit each test message and to compare the corresponding response message from the simulator to an expected response message,

wherein the simulator obtains the response to the test message from the test module.

2. The system of claim 1 wherein the test module is identified by a test module identifier that is transmitted to the simulator in a private data portion of a transmitted test message.

3. The system of claim 1 wherein the test module further comprises a test file containing a test message, an expected response, and the values of network parameters that control the transmission of messages.

4. The system of claim 1 wherein the test module further comprises a timeout value associated with the test message, specifying a time interval during which a corresponding response message should be received.

5. The system of claim 1 in which the test module is written in a tag-formatted language.

6. The system of claim 1 in which the test module is written in extensible markup language (XML).

7. A method executed by a computer for enabling end-to-end testing of network applications, comprising

controlling an application under test connected at one end of a network to transmit a test message in a test module to a response simulator at the other end of the network,

receiving a response message from the simulator to the test message, wherein the response is dictated by a module identical to the test module, and

comparing the response message to an expected response message contained in the test module.

8. The method of claim 7 wherein the test module is identified by a test module identifier, and the method further comprises transmitting the identifier to the simulator in a private data portion of a transmitted test message.

9. The method of claim 7 wherein the test module further comprises a test file containing a test message, an expected response, and the values of network parameters that control the transmission of messages.

10. The method of claim 7 wherein the test module further comprises a timeout value associated with the test message, specifying a time interval during which a corresponding response message should be received.

11. The method of claim 7 in which the test module is written in a tag-formatted language.

12. The method of claim 7 in which the test module is written in extensible markup language (XML).

13. A computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code configured to control an application under test connected at one end of a network to transmit a test message in a test module to a response simulator at the other end of the network;

computer readable program code configured to receive a response message from the simulator to the test message, wherein the response is dictated by a module identical to the test module, and

computer readable program code configured to compare the response to an expected response contained in the test module.

14. The computer program product of claim 13 wherein the test module is identified by a test module identifier, and the computer program product further comprises computer readable program code configured to transmit the identifier to the simulator in a private data portion of a transmitted test message.

15. The computer program product of claim 13 wherein the test module further comprises a test file containing a test message, an expected response, and the values of network parameters that control the transmission of messages.

16. The computer program product of claim 13 wherein the test module further comprises a timeout value associated with the test message and specifying a time interval during which a corresponding response message should be received.

17. The computer program product of claim 13 in which the test module is written in a tag-formatted language.

18. The computer program product of claim 13 in which the test module is written in extensible markup language (XML).
