Main use is for running integration tests but can be used also for deploying an application to any environment after all tests were ran. Some of the features are: Download Mule Standalone from a Maven Repository and install it locally. Start Mule Standalone server. Deploy a Mule application to a server. Undeploy a Mule appliction. Stop a Mule Standalone server. Restart a Mule Standalone server. Assemble a Mule cluster and deploy applications.
