I work on a Google Test-like unit testing framework called DeepState [1] that gives you access to fuzzing and symbolic execution from your C or C++ unit tests. We have a tutorial [2] describing how to use it. It's new and still under development, but shows massive potential, and really brings these software security tools into a more developer-centric workflow.
