Abstract

Provided is a method and system for distributing a test recipe to a tester for conducting a test to determine if a device under test operates as designed. The method includes storing an active test recipe in an active memory in local communication with the tester, and initiating the test of the device under test to be performed by the tester according to a parameter included in the active test recipe stored in the active memory. A second parameter included in a second test recipe is received by the tester while conducting the test of the device under test according to the parameter included in the active test recipe. The method further includes storing the second parameter in a buffer memory in local communication with the active memory, and initiating a transfer of the second parameter from the buffer memory to the active memory. After initiation of the transfer of the second parameter to the active memory, a subsequent test to be performed by the tester according to the second parameter included in the second test recipe is initiated.

Claims

1. A method of distributing a test recipe to a tester that conducts a test to determine if a device under test operates as designed, the method comprising:

storing an active test recipe in an active memory in local communication with the tester, said active memory being located within said tester;

initiating the test of the device under test to be performed by the tester according to a parameter included in the active test recipe stored in the active memory;

receiving a second parameter included in a second test recipe while conducting the test of the device under test according to the parameter included in the active test recipe, wherein receiving the second parameter included in the second test recipe comprises;

referencing an install request to identify the second test recipe to be retrieved; and

in response to said referencing, retrieving the second test recipe identified in the install request;

storing the second parameter in a buffer memory in local communication with the active memory, said buffer memory being within said tester;

initiating a transfer of the second parameter from the buffer memory to the active memory; and

after initiation of the transfer of the second parameter to the active memory, initiating a subsequent test to be performed by the tester according to the second parameter included in the second test recipe.

2. The method according to claim 1 further comprising:

referencing an install request to identify a plurality of additional test recipes to be retrieved and stored in the buffer memory before being stored in the active memory; and

in response to said referencing, retrieving the plurality of additional test recipes identified in the install request in a predetermined order.

3. The method according to claim 2, wherein the predetermined order is based on at least one of:

a priority assigned to each of the plurality of additional test recipes, and an order in which each of the test recipes were designated to be stored in the active memory, and an order that in which each of the test recipes were released to be transmitted to the tester.

4. The method according to claim 2 further comprising marking each of the plurality of additional test recipes identified in the install request stored in the buffer memory as being received.

5. The method according to claim 1 further comprising delaying the initiating of the subsequent test until the transfer of the second parameter to the active memory is complete.

6. The method according to claim 1 further comprising marking the second test recipe as being retrieved in the install request when the second parameter is stored in the buffer memory.

7. The method according to claim 1, wherein referencing the install request occurs at regular intervals.

8. The method according to claim 1, wherein referencing the install request occurs in response to input from a user.

9. The method according to claim 1 further comprising compiling the second test recipe after storing the second test recipe in the buffer memory.

10. The method according to claim 1, wherein initiating the transfer of the second parameter from the buffer memory to the active memory occurs subsequent to completion of the test of the device under test conducted according to the parameter included in the active test recipe.

11. A computer-readable medium storing computer-executable instructions for performing the method of claim 1.

12. A method of distributing a test recipe to a tester that conducts a test to determine if a device under test operates as designed, the method comprising:

storing an active test recipe in an active memory in local communication with the tester, said active memory being located within said tester;

initiating the test of the device under test to be performed by the tester according to a parameter included in the active test recipe stored in the active memory;

receiving a second parameter included in a second test recipe while conducting the test of the device under test according to the parameter included in the active test recipe;

referencing an install request to identify a plurality of additional test recipes to be received and stored in the buffer memory before being stored in the active memory; and

in response to said referencing, receiving the plurality of additional test recipes identified in the install request in order based on when each of the plurality of additional test recipes was added to the install request;

storing the second parameter in a buffer memory in local communication with the active memory, said buffer memory being within said tester;

initiating a transfer of the second parameter from the buffer memory to the active memory; and

after initiation of the transfer of the second parameter to the active memory, initiating a subsequent test to be performed by the tester according to the second parameter included in the second test recipe.

13. The method according to claim 12 further comprising marking each of the plurality of additional test recipes identified in the install request stored in the buffer memory as being received.
