Provided are a computer implemented method, computer program product, and system for partitioning a development environment. A development environment is divided into multiple project areas. Each of the multiple project areas is assigned to a different physical test environment. A solution is assigned to a project area among the multiple project areas. The solution is tested in the assigned physical test environment to modify the physical test environment. The physical test environment associated with the project area is re-initialized without re-initializing other physical test environments.
