Hello, this is Amir Shehata with another LUTF quick tip.

Today we'll go over how the LUTF integrates in the Lustre test infrastructure.

There are multiple ways to run the lustre test scripts but for the sake of this discussion we'll stick with the documented method, shared in the link below.

Top Level Shell test scripts

At the top Lustre tests directory there are two files of interest:
