Unit testing

I am looking to write few simple test cases for pipelines we are working on.
Mainly I need to request a resource  like
http://localhost:8080/myBlock/doc/{id}.xml and compare it with the
existing expected xml document. For comparison, I can use xmlUnit.

However to initialize a block from a junit test class, some work need
to be done. I am not sure, if there is an example showing how to
achieve this.

My pipelines are defined in sitemap.xmap and would like to use this.


Thank you.
