/*
 * A test suite which only makes public HDF5 API calls and which is meant
 * to test the native VOL connector or a specified HDF5 VOL connector (or
 * set of connectors stacked with each other). This test suite must assume
 * that a VOL connector could only implement the File interface. Therefore,
 * the suite should check that a particular piece of functionality is supported
 * by the VOL connector before actually testing it. If the functionality is
 * not supported, the test should simply be skipped, perhaps with a note as
 * to why the test was skipped, if possible.
 *
 * If the VOL connector being used supports the creation of groups, this
 * test suite will attempt to organize the output of these various tests
 * into groups based on their respective HDF5 interface.
