Abstract

Claims (42)

1. A non-transitory computer-readable medium storing instructions that, when executed by a computing device, cause the computing device to perform a method, the method comprising:

communicating with a test process, a system under test (SUT) and at least one downstream system;

receiving a command from the SUT;

performing a first set of procedures when the command from the SUT is a first type;

performing a second set of procedures when the command from the SUT is a second type; and

receiving preprogrammed failure information from the test process wherein the preprogrammed failure information is received from the test process immediately preceding a failure during a test.

2. The non-transitory computer-readable medium of claim 1 , wherein the preprogrammed failure information is received from the test process prior to the start of a test.

3. The non-transitory computer-readable medium of claim 1 , wherein the method further comprises checking the command received from the SUT against the preprogrammed failure information received from the test process.

4. The non-transitory computer-readable medium of claim 3 , wherein the first type is a nonprogrammed command, and wherein the first set of procedures includes:

forwarding the command from the SUT to one of the at least one downstream system that the command from the SUT is intended for;

receiving a response from the one of the at least one downstream system; and

echoing the response from the one of the at least one downstream system back to the SUT.

5. The non-transitory computer-readable medium of claim 3 , wherein the second type is a preprogrammed failure command in the preprogrammed failure information, and wherein the second set of procedures includes one of automatically replying back to the SUT with a corresponding error code and not sending any response back to the SUT.

6. The non-transitory computer-readable medium of claim 5 , wherein the corresponding error code is detailed in the preprogrammed failure information that is received from the test process.

7. A computing device comprising:

a non-transitory memory for storing an application, the application for automatically:

receiving preprogrammed failure information from a test process that is communicatively coupled with the computing device;

determining whether a command received from a system under test (SUT) corresponds with the preprogrammed failure information, wherein the SUT is communicatively coupled with the computing device and the test process;

based on the determination that the command does not correspond with the preprogrammed failure information, returning a first data to the SUT; and

based on the determination that the command corresponds with the preprogrammed failure information, returning a second data to the SUT, wherein returning the second data to the SUT includes obtaining an associated error code from the preprogrammed failure information, wherein the second data is the associated error code from the preprogrammed failure information; and

a processing component coupled to the memory, the processing component configured for processing the application.

8. The computing device of claim 7 , wherein returning a first data to the SUT includes:

forwarding the command to a downstream system; and

receiving a response from the downstream system, wherein the first data is the response from the downstream system.

9. A system for testing a system under test, the system comprising:

a system under test (SUT);

a test process for testing the SUT, wherein the test process includes preprogrammed failure information; and

a transparent proxy downstream of the SUT and the test process, wherein the transparent proxy is configured to:

receive a command from the SUT;

perform a first set of procedures when the command from the SUT is a first type;

perform a second set of procedures when the command from the SUT is a second type; and

receive preprogrammed failure information from the test process,

wherein the preprogrammed failure information is received from the test process immediately preceding a failure during a test.

10. The system of claim 9 , wherein the preprogrammed failure information is received from the test process prior to the start of a test.

11. The system of claim 9 , wherein the transparent proxy is further configured to check the command received from the SUT against the preprogrammed failure information received from the test process.

12. The system of claim 11 , wherein the first type is a nonprogrammed command, and wherein the first set of procedures includes:

the transparent proxy forwarding the command from the SUT to a downstream system that the command from the SUT is intended for;

the transparent proxy receiving a response from the downstream system; and

the transparent proxy echoing the response from the downstream system back to the SUT.

13. The system of claim 11 , wherein the second type is a preprogrammed failure command in the preprogrammed failure information, and wherein the second set of procedures includes one of the transparent proxy automatically replying back to the SUT with a corresponding error code and the transparent proxy not sending any response back to the SUT.

14. The system of claim 13 , wherein the corresponding error code is detailed in the preprogrammed failure information that is received from the test process.

15. The system of claim 9 , wherein the test process also includes a sequence of instructions for testing the SUT.
