I recently posted a blog post about CodeYam, which is a software simulator. It creates simulations of every aspect of a software application - basically every function, both in isolation and in the context of the app or other function that import the original function.

We've put together a brief demo demonstrating how the software simulator can benefit a pull request workflow, creating simulations of all changes and making it easy to add/edit simulations and save them as part of a test suite. Would love to hear any thoughts people have on it.
