 /**
  * @brief TinyUSB Teardown specific testcase
+ *
+ * Scenario:
+ * - Installs the tinyUSB driver via esp-tinyusb wrapper with 1xCDC class device
+ * - Awaits device configuration be the Host (TEARDOWN_ATTACH_TIMEOUT_MS)
+ * - Awaits the terminal connection (TEARDOWN_ATTACH_TIMEOUT_MS)
+ * - Expects the command sequence from the Host (TEARDOWN_COMMAND_TIMEOUT_MS)
+ * - Replies with the response sequence to the Host
+ * - Awaits terminal disconnection (TEARDOWN_ATTACH_TIMEOUT_MS)
+ * - Teardowns the tinyUSB driver via esp-tinyusb wrapper
+ * - Repeats the steps from the step.1 N times (where N = TEARDOWN_AMOUNT)
+ * - Verifies amount of attempts and memory leakage (attempts should be 0)
+ *
+ * command sequence[] = ep_size * 0xAA
+ * response sequence[] = ep_size * 0x55
+ *
+ * Hint: Values 0xAA and 0x55 were selected to verify the buffer memory integrity,
+ * as the 0xAA and 0x55 are the inversion of each other and the data bits in the same position changes from 1 to 0 in every transaction.
