We use Sikuli for automatiom tests on both Windows and Mac. Other than occasional issues with its image recognition features it works great and serves us well.

We use Sikuli for automatiom tests on both Windows and Mac. Other than occasional issues with its image recognition features it works great and serves us well. We have Jenkins automation jobs spin up VMs in VirtualBox, load build artifacts on the VM, and run Sikuli tests. All test output gets pulled back into the Jenkins output and parsed for successes/failures. Makes it possible for us to test across different OSes use the same Sikuli scripts.
