Automated testing of LabView applications

[RobBovill]

I'm looking for a tool that I can use for automated functional and regressing testing of LabView VIs.  I'm not looking for unit testing tools, as I'm not the developer.  I'm the software test engineer for a team that is building applications in LabView that I need to verify.  I have tried AutoIt, but the inspector cannot read the contents of the VI, so I can't interact with it.  I'm looking into TestPlant's eggPlant Functional, but this uses image capture techniques, which I find to be less robust.  Does anyone know of any third-party (preferably not NI) tools that interact with LabView VIs for this kind of testing?

I did find this post,

but they go into using NI tools for unit testing.  Ideally, I would like something that works with Robot-Framework (http://robotframework.org/), but any other solutions are welcome.
