I am looking for tools or frameworks that can either generate test cases or aid in software testing.
So far I have found the following:

These tools apply mostly to Java, but am also looking for .NET or other languages.
Can anyone propose other tools
Dotnet Testdatagenerator NBuilder
Language agnostic all-pair testing
We have used PICT as a tool to successfully minimize the amount of testcases while still being reasonable confident to have most cases covered.
To add to the list above, if you're looking at Pairwise (Combinatorial) test case generation, the complete, (usually) updated and an EXTENSIVE list of ALL such tools that let you generate test-cases, alongside analysis of the effectiveness of each, research papers et. al. can be found at http://www.pairwise.org/
