Wondering if anyone has tooling to test a workflow as it exists in a specific galaxy instance? I'm looking to test some of my user's manually built workflows in our galaxy instance to make sure that we can detect issues when they arise (e.g. due to changes in the interfaces of our non-toolshed installed tools)

Ideally something like: 

$ my_tool $galaxy_url $api_key $workflow_id
  <set of files and their input IDs in the workflow>
> report.xunit.xml

If not we'll build something soon.

Cheers,
Eric
