A virtual integration test system includes a computer configured to receive data indicative of measured dimensions of as-built components. The computer is also configured to perform a motion mechanics simulation on at least two deformation-uncritical components of the as-built components and perform a deformation mechanics simulation on at least one deformation-critical component of the as-built components. The motion mechanics simulation and the deformation mechanics simulation are performed concurrently within a simulation environment. In addition, the computer is configured to determine interface and integration compatibility of the as-built components based on the motion mechanics simulation and the deformation mechanics simulation, and to output an output signal indicative of the interface and integration compatibility of the as-built components.
