A software automation build system including a one or more source code repositories, the one or more source code repositories including source code of a software product and a source code for a build system. The source code for the build system stores a configuration specifying a build and test environment as a configuration file that can be accessed remotely by users to replicate a consistent virtual build and test environment for developing and testing code of the software product at different locations, using virtual machines. The system may include one or more instances of the build system based on the configuration. The system may save versions of the configuration so that multiple versions of the build system can be accessed and built virtually.
