/** @brief
 *
 * The is a basic test case which does the following:
 * - 01. create a key with handle hkey1
 * - 02. write data of hkey1
 * - 03. opens KV with 2nd handle, hkey2
 * - 04. read data with hkey2 and make sure its the same as that written with hkey1
 * - 05. write new data with hkey2
 * - 06. delete hkey2
 * - 07. close hkey2
 * - 08. read hkey1 and make sure the data is the newly written data i.e. the key hasnt
 *       been deleted yet
 * - 09. try to open KV and make sure unable to do so, as KV is deleting
 * - 10. close hkey1
 * - 11. try to open KV and make sure unable to do so because its now been deleted
 * - 12. create new KV with same key_name to make sure can re-create the key again.
 *
 * @return on success returns CaseNext to continue to next test case, otherwise will assert on errors.
