BizUnit - Pipeline Test Steps missing

问题:

I've downloaded BizUnit package with nuGet Package Console. I'd like to test my custom pipeline component. According to source respository ( click ), there is a BizUnit.TestSteps.BizTalk.Pipeline namespace containing, i.e ExecuteSendPipelineStep class which I want to use.

But I can't find it on my machine.

I use VS 2013 Professional and BizTalk 2013. What am I doing wrong?
