The authors describe how the authors integrate, build, and test the Open Science Grid (OSG) software stack, which is used to provide a production quality infrastructure for grid sites and users across OSG to run their grid jobs. The software stack is sufficiently complex that building and testing the software stack is non-trivial and requires a variety of types of testing including internal integration testing as well as end-user testing. The Open Science Grid (OSG) is a national, distributed computing grid for data-intensive research. It brings together resources from campuses and research communities around the nation and the world into a common, shared grid infrastructure via a common set of software.
