  The Safe Machine Parameters Controller (SMPC) ensures the correct configuration of the LHC machine protection system, and that safe injection conditions are maintained throughout the filling of the LHC machine. The SMPC receives information in real-time from measurement electronics installed throughout the LHC and SPS accelerators, determines the state of the machine, and informs the SPS and LHC machine protection systems of these conditions. This paper outlines the core concepts and realization of the SMPC test-bench, based on a VME crate and LabVIEW program. Its main goal is to ensure the correct function of the SMPC for the protection of the CERN accelerator complex. To achieve this, the tester has been built to replicate the machine environment and operation, in order to ensure that the chassis under test is completely exercised. The complexity of the task increases with the number of input combinations which are, in the case of the SMPC, in excess of 2364. This paper also outlines the benefits and weaknesses of developing a test suite independently of the hardware being tested, using the "V" approach.
