    **Validation Test Description**
    This unit test verifies the formationBarycenter module. It checks the barycenter of three spacecraft using both
    cartesian coordinates and orbital elements weighted averaging.
    **Test Parameters**
    The test parameters used are the following:
    Args:
        accuracy (float): absolute accuracy value used in the validation tests
    **Description of Variables Being Tested**
    In this file we are checking the values of the variables
    - ``barycenter``
    - ``barycenterVelocity``
    - ``barycenterC``
    - ``barycenterVelocityC``
    which represent the center of mass position and velocity vectors. The variables ending in ``C`` are pulled from the
    C-wrapped navigation output message, whereas the other two come from the usual C++ message. All these variables are
    compared to ``trueBarycenter`` and ``trueBarycenterVelocity``, which contain their true values.
    As stated, both the C and C++ wrapped message outputs are checked.
