Abstract

In a diagnostic application, a plurality of independent test modules are executed in a multi-tasking fashion. The diagnostic application is modular with a front end module issuing commands to lower level modules. A lower level test dispatcher module receives information from the plurality of test modules pertaining to test parameters, including whether the test module is multitaskable. A test dispatcher controls the launching of the test modules according to the test parameters. A test definition tool is provided to graphically develop test scripts by moving icons from one list to another. The output of the test definition tool is a scripting language readable by the diagnostic application.

Claims

1. A method of testing a peripheral device in a computer system, the method comprising the steps of:

(a) providing a number of independent test modules as independent library modules along with associated peripheral devices, tests and parameters;

(b) loading and initializing the test modules, each test module identifying to a test front end program the peripheral devices for which it is responsible and a number of tests available to perform, each test having a number of parameters;

(c) the test front end program permitting selection of some subset of the test modules for execution;

(d) providing a list of the subset of the test modules and the associated peripheral devices, tests and parameters to a test dispatcher by each test module; and

(e) dispatching the test modules for execution in accordance with the list of peripheral devices, tests and parameters.

2. The method of claim 1, wherein the peripheral device is a network interface controller.

3. The method of claim 1, wherein the peripheral device is a multifunction I/O peripheral.

4. The method of claim 3, wherein the multifunction I/O peripheral includes multiple serial ports, a parallel port and a floppy disk controller.

5. The method of claim 1, wherein the peripheral device is a video controller.

6. The method of claim 1, wherein the peripheral device is a storage device.

7. The method of claim 6, wherein the storage device is a hard disk drive and wherein the tests that can be performed on the hard disk drive include a sequential seek test, a random seek test, and a converging seek test.

8. A computer system, comprising:

a processor;

a video display system coupled to said processor; and

a plurality of peripheral devices coupled to said processor,

wherein the processor is capable of performing the following steps;

(a) providing a number of independent test modules for the peripheral devices as independent library modules along with associated tests and parameters;

(b) loading and initializing the test modules, each test module identifying to a test front end program the peripheral device for which it is responsible and a number of tests available to perform, each test having a number of parameters;

(c) the test front end program permitting selection of some subset of the test modules for execution;

(d) providing a list of the subset of the test modules and the associated peripheral devices, tests and parameters to a test dispatcher by each test module; and

(e) dispatching the test modules for execution in accordance with the list of peripheral devices, tests and parameters, the executed test modules testing their associated peripheral devices.

9. The computer system of claim 8, wherein one of the peripheral devices is a network interface controller.

10. The computer system of claim 8, wherein one of the peripheral devices is a multifunction I/O peripheral.

11. The computer system of claim 10, wherein the multifunction I/O peripheral includes multiple serial ports, a parallel port and a floppy disk controller.

12. The computer system of claim 8, wherein one of the peripheral devices is a keyboard controller.

13. The computer system of claim 8, wherein one of the peripheral devices is a storage device.

14. The computer system of claim 13, wherein the storage device is a hard disk drive and wherein the tests that can be performed on the hard disk drive include a sequential seek test, a random seek test, and a converging seek test.

15. A computer system, comprising:

a processor;

a video display system coupled to said processor;

a hard disk drive system coupled to said processor; and

a plurality of peripheral devices coupled to said processor,

wherein the processor is capable of performing the following steps;

(a) providing a number of independent test modules for the peripheral devices as independent library modules along with associated tests and parameters;

(b) loading and initializing the test modules, each test module identifying to a test front end program the peripheral device for which it is responsible and a number of tests available to perform, each test having a number of parameters;

(c) the test front end program permitting selection of some subset of the test modules for execution;

(d) providing a list of the subset of the test modules and the associated peripheral devices, tests and parameters to a test dispatcher by each test module; and

(e) dispatching the test modules for execution in accordance with the list of peripheral devices, tests and parameters, the executed test modules testing their associated peripheral devices.

16. The computer system of claim 15, wherein one of the peripheral device is a network interface controller.

17. The computer system of claim 15, wherein one of the peripheral devices is a multifunction I/O peripheral.

18. The computer system of claim 17, wherein the multifunction I/O peripheral includes multiple serial ports, a parallel port and a floppy disk controller.
