/**
 * \brief       Function pointer type for test function wrappers.

 * underlying test function. Both the wrapper and the underlying function
 * return void. Test wrappers assume that they are passed a suitable
 * parameter array and do not perform any error detection.
 *
 * \param param_array   The array of parameters. Each element is a `void *`
 *                      which the wrapper casts to the correct type and
 *                      dereferences. Each wrapper function hard-codes the
 *                      number and types of the parameters.
