   1.826 +
   1.827 +@SYMTestPriority		Medium
   1.828 +
   1.829 +@SYMTestStatus			Implemented
   1.830 +
   1.831 +@SYMTestActions			1. Create a file store object from file stream cache using current session handle
   1.832 +						2. Create new file store object using some dummy session handle
   1.833 +						3. Check two file store object belongs to the corresponding dummy session handle.
   1.834 +						4. Close file store and check 
   1.835 +								- if corresponing session's handle file store used to close.
   1.836 +								- if we send wrong session handle none of the file store should close
   1.837 +								- if we haven't send any session handle close all the file store object irrespective of the session handle
   1.838 +
   1.839 +@SYMTestExpectedResults	1. File store should close only for the corresponding session, while disconnecting the session
   1.840 +						2. By flushing cache should close all file stores and reset cache entries, irrespective of the session
