* @brief Unit tests for the configuration manager.
*
* Parts of the file ``cpukit/sapi/src/getconfigmax.c`` are only executed when
* unlimited objects are configured. The space qualified code subset does not
* support this feature. This test exercises the code parts otherwise not
* reached in order to achieve full code coverage.
*
* This test case performs the following actions:
*
* - Call get_config_max() indirectly through
* rtems_configuration_get_maximum_semaphores() with a specially manipulated
* argument to enter an if-branch only accessed when unlimited objects are
* configured.
*
* - The value returned by the function call must be the one artificially
* injected by this test.
