The Pipeline steps use Tomas Restrepo’s Pipeline Testing Library.
I had originally planned on incorporating Bram’s steps into Extensions as I wrote previously. However after discussing with Kevin, those plans changed so its now in the core BizUnit.
There is a similar MapExecutingStep in Extensions that has been around for a while now and when I get some time I’ll take a closer look at Bram’s step and see if there are any differences that are worth keeping or retire the Extensions step if not required anymore. I have had a couple of bugs reported on Extensions beta-1 which I shall fix soon and get the RTM released which will be compiled against BizUnit 3.1.
