+ * Test Case Name: Drivers Core Test
+ * 
+ * Test Objectives:
+ * - Validate the correctness and consistency of the rt_device_find() API in the RT-Thread device management subsystem.
+ * - Test rt_device_find() and rt_console_get_device().
+ * 
+ * Test Scenarios:
+ * - Locate a known console device by its actual name retrieved at runtime.
+ * - Attempt to find the same device using the predefined macro RT_CONSOLE_DEVICE_NAME.
+ * - Verify identity consistency when querying the same device through different but equivalent name sources.
+ * 
+ * Verification Metrics:
+ * - rt_device_find() must return a non-NULL pointer when a valid device name is provided.
+ * - Pointers returned for the same logical device (via different name expressions) must be identical.
+ * - When RT_CONSOLE_DEVICE_NAME differs from the actual console name, two distinct but valid devices must be found.
+ * - All assertions must pass without triggering test failure.
+ * 
+ * Dependencies:
+ * - Hardware requirements: QEMU emulator or any hardware platform that supports RT-Thread with console device registration.
+ * - Software configuration:
+ *     - RT_USING_UTEST must be enabled (select "RT-Thread Utestcases" in menuconfig).
+ *     - BSP_UTEST_DRIVERS_CORE must be enabled (enable via: RT-Thread Utestcases -> Kernel components -> drivers -> Driver core Test).
+ * - Environmental assumptions: The system has initialized the console device before test execution.
+ * 
+ * Expected Results:
+ * - The test will pass silently if all assertions hold.
+ * - Console will output: "[ PASSED ] [ result ] testcase (components.drivers.core.device_find)".
