This document discusses techniques for automating the setup of developer sandboxes using metadata tools and source control. It emphasizes creating repeatable processes for deploying configuration versions, loading test data sets, and running unit tests. This allows for environment parity, more agility in development, and continuity across environments. Specific tools and targets discussed include the Force.com Migration Tool, source control systems like Git, and sample Ant build scripts for deploying changes, purging data, and executing tests. Roadmap items are also presented for improving deployment speed and exposing more metadata through the API.
