Creating unit test to subvi that only gives an output an STD output to CMD

[77maxmustermann]

So I wrote a program that sends a message to the CMD that opened up my program through the console Invoke Node but I didnt find a way to read what I wrote so I can made a Teardown VI for this SUB-VI for testing purposes.

I tried using the invoke Node for console "Readline" but it only waits for me to echo a statement so it can read it and doesnt read what I already wrote.

Any idea how to read the messages that I sent to the CMD through Labview.

Hi 77maxmustermann,

You can just copy the command from the cmd to clipboard and then read it in LabVIEW.

The great example is provided in this post:

Hope this helps.
