* @brief Tests some @ref RTEMSAPIClassicClock directives.
*
* This test case performs the following actions:
*
* - Use the rtems_clock_get_ticks_since_boot() directive before and after
* exactly one clock tick.
*
* - Check that clock tick gets incremented.
*
* - Use the rtems_clock_get_ticks_since_boot() directive before and after
* exactly one clock tick.
*
* - Check that clock tick gets incremented.
*
* - Use the rtems_clock_get_ticks_per_second() directive.
*
* - Check that rtems_clock_get_ticks_per_second() actually returns 1us /
* CONFIGURE_MICROSECONDS_PER_TICK.
*
* - Use the rtems_clock_get_ticks_per_second() directive.
*
* - Check that rtems_clock_get_ticks_per_second() actually returns 1us /
* CONFIGURE_MICROSECONDS_PER_TICK.
