-/* Function: test_actual_io_mode
- *
- * Purpose: tests one specific case of collective I/O and checks that the
- *          actual_chunk_opt_mode property and the actual_io_mode
- *          properties in the DXPL have the correct values.
- *
- * Input:   selection_mode: changes the way processes select data from the space, as well
- *          as some dxpl flags to get collective I/O to break in different ways.
- *
- *          The relevant I/O function and expected response for each mode:
- *              TEST_ACTUAL_IO_MULTI_CHUNK_IND:
- *                  H5D_mpi_chunk_collective_io, each process reports independent I/O
- *
- *              TEST_ACTUAL_IO_MULTI_CHUNK_COL:
- *                  H5D_mpi_chunk_collective_io, each process reports collective I/O
- *
- *              TEST_ACTUAL_IO_MULTI_CHUNK_MIX:
- *                  H5D_mpi_chunk_collective_io, each process reports mixed I/O
- *
- *              TEST_ACTUAL_IO_MULTI_CHUNK_MIX_DISAGREE:
- *                  H5D_mpi_chunk_collective_io, processes disagree. The root reports
- *                  collective, the rest report independent I/O
- *
- *              TEST_ACTUAL_IO_DIRECT_MULTI_CHUNK_IND:
- *                  Same test TEST_ACTUAL_IO_MULTI_CHUNK_IND.
- *                  Set directly go to multi-chunk-io without num threshold calc.
- *              TEST_ACTUAL_IO_DIRECT_MULTI_CHUNK_COL:
- *                  Same test TEST_ACTUAL_IO_MULTI_CHUNK_COL.
- *                  Set directly go to multi-chunk-io without num threshold calc.
- *
- *              TEST_ACTUAL_IO_LINK_CHUNK:
- *                  H5D_link_chunk_collective_io, processes report linked chunk I/O
- *
- *              TEST_ACTUAL_IO_CONTIGUOUS:
- *                  H5D__contig_collective_write or H5D__contig_collective_read
- *                  each process reports contiguous collective I/O
- *
- *              TEST_ACTUAL_IO_NO_COLLECTIVE:
- *                  Simple independent I/O. This tests that the defaults are properly set.
- *
- *              TEST_ACTUAL_IO_RESET:
- *                  Perfroms collective and then independent I/O wit hthe same dxpl to
- *                  make sure the peroperty is correctly reset to the default on each use.
- *                  Specifically, this test runs TEST_ACTUAL_IO_MULTI_CHUNK_NO_OPT_MIX_DISAGREE
- *                  (The most complex case that works on all builds) and then performs
- *                  an independent read and write with the same dxpls.
- *
- *          Note: DIRECT_MULTI_CHUNK_MIX and DIRECT_MULTI_CHUNK_MIX_DISAGREE
- *          is not needed as they are covered by DIRECT_CHUNK_MIX and
- *          MULTI_CHUNK_MIX_DISAGREE cases. _DIRECT_ cases are only for testing
- *          path way to multi-chunk-io by H5FD_MPIO_CHUNK_MULTI_IO insted of num-threshold.
- *
- * Modification:
- *  - Refctore to remove multi-chunk-without-opimization test and update for
- *    testing direct to multi-chunk-io

- *
- * Input:
- *    selection_mode: various mode to cause broken collective I/O
- *    Note: Originally, each TEST case is supposed to be used alone.
- *          After some discussion, this is updated to take multiple TEST cases
- *          with '|'.  However there is no error check for any of combined
- *          test cases, so a tester is responsible to understand and feed
- *          proper combination of TESTs if needed.
- *
- *
- *       TEST_COLLECTIVE:
- *         Test for regular collective I/O without cause of breaking.
- *         Just to test normal behavior.
- *
- *       TEST_SET_INDEPENDENT:
- *         Test for Independent I/O as the cause of breaking collective I/O.
- *
- *       TEST_DATATYPE_CONVERSION:
- *         Test for Data Type Conversion as the cause of breaking collective I/O.
- *
- *       TEST_DATA_TRANSFORMS:
- *         Test for Data Transfrom feature as the cause of breaking collective I/O.
- *
- *       TEST_NOT_SIMPLE_OR_SCALAR_DATASPACES:
- *         Test for NULL dataspace as the cause of breaking collective I/O.
- *
- *       TEST_NOT_CONTIGUOUS_OR_CHUNKED_DATASET_COMPACT:
- *         Test for Compact layout as the cause of breaking collective I/O.
- *
- *       TEST_NOT_CONTIGUOUS_OR_CHUNKED_DATASET_EXTERNAL:
- *         Test for Externl-File storage as the cause of breaking collective I/O.
- *
- *       TEST_FILTERS:
- *         Test for using filter (checksum) as the cause of breaking collective I/O.
- *         Note: TEST_FILTERS mode will not work until H5Dcreate and H5write is supported for mpio and filter feature. Use test_no_collective_cause_mode_filter() function instead.
