Abstract

A method and system for automatically testing a universal serial bus (USB) design for a plurality of test environments is provided. A user may be queried for information regarding the USB design being tested. One of a plurality of test environments is then automatically selected to be tested. The selected test environment is then used to test the universal serial bus design. The steps are then repeated for a desired number of test environments. The steps may be repeated until the universal serial bus design has been tested for all of the plurality of test environments. A system is provided for testing a USB design includes a query unit which queries a user for information regarding the universal serial bus design. A test configuration module automatically tests the universal serial bus design for a plurality of test configurations based on the information regarding the universal serial bus design.

Claims

1. A method for automatically testing a universal serial bus design comprising the steps of:

(a) automatically selecting one of a plurality of test environments;

(b) testing the universal serial bus design based on the selected one of the test environments; and

(c) repeating steps (a) and (b).

2. The method as recited in claim 1 wherein the step of (c) repeating steps (a) and (b) comprises the step of:

repeating steps (a) and (b) until the universal serial bus design has been tested for all of the plurality of test environments.

3. The method as recited in claim 1 wherein the step of (a) automatically selecting one of a plurality of test environments comprises the step of:

selecting one of a plurality of end points.

4. The method as recited in claim 3 wherein the step of (a) automatically selecting one of a plurality of test environments comprises the step of:

selecting one of the end points and an associate one of one or more configurations.

5. The method as recited in claim 1 comprising the step of:

reporting test results.

6. The method as recited in claim 5 wherein the step of reporting test results comprises the step of:

reporting test results substantially immediately if one of the selected test environments fails.

7. The method as recited in claim 5 wherein the step of reporting test results comprises the step of:

reporting test results after all of the test environments have been tested.

8. A method for automatically testing a universal serial bus design comprising the steps of:

querying a user for information regarding the universal serial bus design;

automatically selecting one of a plurality of test configurations for the universal serial bus design based on the information regarding the universal serial bus design;

testing the universal serial bus design for the selected one of the test configurations;

automatically selecting another one of the test configurations for the universal serial bus design; and

testing the universal serial bus design for the other one of the test configurations.

9. The method as recited in claim 8 wherein the step of automatically selecting one of the test configurations for the universal serial bus design comprises the steps of:

selecting an end point for the universal serial bus design;

selecting a configuration for the universal serial bus design; and

selecting an interface for the universal serial bus design.

10. The method as recited in claim 9 wherein the step of automatically selecting one of the test configurations for the universal serial bus design comprises the step of:

selecting an alternate setting for the universal serial bus design.

11. The method as recited in claim 10 comprising the step of:

reporting test results.

12. The method as recited in claim 11 wherein the step of reporting test results comprises the step of:

reporting test results substantially immediately if one of the selected test environments fails.

13. The method as recited in claim 11 wherein the step of reporting test results comprises the step of:

reporting test results after all of the test environments have been tested.

15. The system as recited in claim 14 wherein the test configuration module comprises a configuration unit for setting a configuration value for each of the test configurations.

16. The system as recited in claim 15 wherein the test configuration module comprises an interface unit for setting an interface value for each of the test configurations.

17. The system as recited in claim 16 wherein the test configuration module comprises an end point unit for setting an end point value for each of the test configurations.

18. The system as recited in claim 17 wherein the test configuration module comprises an alternate setting unit for setting an alternate setting value for each of the test configurations.

19. The system as recited in claim 18 comprising a report unit for reporting test results for the test configurations.

20. The system as recited in claim 18 comprising a report unit for reporting test results after each test configuration is tested.

14. A system for testing a universal serial bus design comprising:

a query unit for querying a user for information regarding the universal serial bus design; and

a test configuration module for automatically testing the universal serial bus design for a plurality of test configurations based on based on the information regarding the universal serial bus design.
