Abstract: In accordance with embodiments, there are provided mechanisms and methods for validating changes before submission to a source control system, which can provide developers with a remote server where changelists may be uploaded, specified tests may be run, and results may be returned to the developer. The ability to provide a remote server for changelist uploads, automated source code compilations, automated test executions, and the automatic return of results, tends to enable developers to quickly and efficiently make source code design changes and avoid to build breakages.

Abstract: An automated system is provided to support massive scale grid of machines in a rapid, multi-developer coding environment. The system has virtual testing environments that are created from template machines, supporting various software versions for various code branches. The grid is built by having a small subset of template machines (e.g. with Oracle 9g, 10g, and application server installations), images of the template machines, virtual machine instances created by applying one or more of the image templates, which then are used by the virtual testing environment. Upon receipt of code changes, changes are checked-out, compiled, tested on various test feeds on a virtual testing environment, which is destroyed and re-created after every test run. Any software version upgrades or bug fixes need to be applied only to the template machines. The number of virtual machines associated with any particular template machine is dynamically configurable to provision for optimal use of testing machines.
