How can I determine UUT Pass (so far) using LabView Test Executive 5.1?

[Al_S]

I'm using Labview Test Executive 5.1 (mass compiled for LabView 6.1). How can I check if my UUT is passing while the test sequence is executing?

For example: I have 10 steps in my sequence.
During the execution of the VI for step 8, I need to know if all previous steps (1 thru 7) passed.
How can I check UUT Pass (so far) while the sequence is still running?

I don't want to change all the steps in my sequence to set a global UUT Pass variable. The Test Executive obviously knows UUT Pass at the end of the sequence, but how does it know?

I see for the report generation, Test Executive VI's Format Test Report.vi and Format UUT Report.vi read temp\uutrtemp.dat, but that file doesn't exist
at the point I need to check Pass/Fail. Those VIs use a bunch of undocumented stack (?) functions which make them hard to read, but they start by reading a file that apparently gets created after the sequence is complete. I can't find the VI that creates uutrtemp.dat because most of the Test Executive VIs' diagrams are password protected.

Isn't there a simple function that returns Pass/Fail?

Thanks,

Al

It has been a very long time since I used Test Executive (I moved to TestStand when it came out) so I refreshed my memory by reviewing the manual I found here. Each VI requires Test Data.ctl. The TE uses that to update Test Result.ctl and as each step executes, creates an array of results into Sequence Results.ctl. I don't remember how, but I think you could process Sequence Results in a pre-step. This may have been built into the TE or I may have modified the program to add this functionality.

I'd also like to mention that I think TestStand is a much superior test manager in every way and you can import sequences created for the ol
d and no longer supported TE.

Are you wanting to stop the sequence of VIs if one fails? If so, you can "Stop on Any Failure" option in Sequence>>Sequence Options. This setting overrides the FAIL option on any step.

No, thanks. I don't want to stop on a failure. A VI in the sequence (step 8 in my previous example), will perform function A if all previous sequence steps passed, and will perform function B if any failed. Then the sequence will continue and exectute the remaining steps.
How do I check if all previous steps passed while the sequence is still executing?

Thanks Dennis!

After you pointed me in the right direction, it turned out to be very easy to do. I was spinning my wheels for a day and a half, but after your note, I had something working in an hour. Here's the LV 6.1 VI (calling a VI from Test Executive 5.1).

Thanks!
