how to use notification step for parallel testing

[kk777]

Hello All,

Can anyone tell me how to use notification step in test stand with multiple main sequence.

for example, i have Test_1.seq and Test_2.seq and expect to start run these two sequence in parallel. but my requirement is Test_1.seq has to complete the execution first and send notification to Test_2.seq, where as Test_2.seq has to wait until it gets notification from Test_1.seq. If Test_2.seq gets notification from Test_1.seq  it can proceed for rest of the testing.

Any idea how this can be achieved in teststand? 

thanks,

In your Test_1 sequence, you create a notification. Then, you call Test_2 in a separate thread. In Test_2, you put a Notification wait using the name you used to create the notification. When ready in Test_1, you send a notification (Set or Pulse) to all threads or to just one thread. You can pass a value. Then you wait in Test_1 that Test_2 finishes its task.

Notice that you do not need to have 2 separate sequence files. You can have more than 1 sequence in the same sequence file.

Attached in an example of what I describe above; using only one sequence file, MainSequence is Test_1. 

P.S.: You might want to look into the Batch or Parallel process models. A lot of the heavy lifting has been done when it comes to parallel testing.

Hi,

Thanks for your reply. it is working now. also i would like to know is there any option to know which slots or sockets currently running in test stand.

If you use the parallel or batch process model, you have access to "RunState.TestSockets.MyIndex" that gives you an index starting at 0 for each of the parallel tests.
