Are there any good TDD tools or resources for VB6?

For my sins in a previous life I am currently faced with having to modify some legacy VB6 COM+ code.

The client absolutely does not want us to upgrade this code to .NET so that is not an option in this case.

I am uncomfortable touching this code without adding unit tests to it, but while I am experienced in using tools in the XUnit family and in the practices of TDD, I have never worked in VB6 since learning these skills, so unit testing VB6 is completely new to me.

I see that there is a product called SimplyVBUnit, as well as VBUnit, but the online documentation for them seems limited. Has anyone used either of these tools? What are the main differences between them? Is there another tool that I should be considering?

Your question is still open (and showing as unanswered).

As well as the previously mentioned SO question, Are there any good TDD tools or resources for VB6?, there are a couple of others.

VB Lite Unit: http://sourceforge.net/projects/vb-lite-unit/

VbUnit2: http://code.google.com/p/vbunit2/
