+ *
+ * Purpose: tests one specific case of collective I/O and checks that the

+ * 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
