reg wmTest suite to assert pipeline output

Hi,

I am exploring the wmTestsuite for unit testing flow services. Is there a way to assert the output pipeline of a flow service in wmTestsuite (using Xpath expression)?

I tried using like “/Pipeline/header/status”, but could not got any success.

My flow service do not have any output and I would like to assert by accessing the output pipeline.

Kindly share your thoughts… Thanks.
