A Testery Deployment is a representation of each deployment that happens in any of your environments. When a build system tells Testery when a deployment happens, it gives Testery users more insight into knowing what is deployed where, in what environment, what version of code, and what tests have been run against a deployment. It also allows users that do not normally have much control over the build process to make decisions and easily change what tests get run, in what environments and when they should run.
