Hello,
Since I haven’t found anything like that on the internet, I though I could share a bit.
We were looking for a solution to the difficulty of Test Driven Development with Corona, and here’s what we have found to work.
We started to use Busted test framework [ https://github.com/Olivine-Labs/busted ], which has a nice solution for Corona SDK apis - mocks.
I am not going to go into how Busted works, you can find it at Olivine-Labs web page.
I have created a git repository with our mocks. I am going to update them as we create new ones or modify the existing.
For now they are pretty basic, it’s just what we need and require. We’ve got some more of them, but I have to clean them up before I share them 
Anyway… I hope someone will find them helpful.
If you need any help with it, let me know.
This is an area we are still learning about, but for now it looks very promising and I have not yet found a scenario I can’t test with it.
The git repo is: https://github.com/Cluain/corona-busted
Thanks,
Krystian
