Another approach to automated generation of test cases is through a process of turning traces into tests. Valid uses of code already exist. These are in the application itself and for a library you can find published code that makes use of it. A recent paper [1] covers this subject and demonstrates in R achieving better code coverage than hand written tests and does so for a large portion of published libraries. I think this is a very interesting direction for automated test case generation. If you look at snapshot testing [2] it reminds me very much of that.
