Perhaps often it is more useful to use MPI_WAIT rather than MPI_TEST type fucntions, because at MPI_WAIT point it will be taken care of communication completion, automatically, which may be necessary before going ahead. with MPI_TEST it would become the responsibility of the programmer to handle the situation if the test is FALSE/FAILED.
Yes; you can use any of the various flavors of the MPI_TEST* functions.
