+@SYMTestCaseDesc        CStreamStore tests.
+@SYMTestActions         CStreamStore provides couple of virtual methods in its private section:
+                        DoExtendL(), DoDeleteL(), DoReplaceL(), DoReclaimL().
+                        They are no-ops and are expected to be overriden in the class derived from
+                        CStreamStore. Their implementations leave with KErrNotsupported. 
+                        The test uses a class derived from CStreamStore, which class does not implement
+                        virtuals mentioned above. These virtuals should leave with KErrNotSupported when called.
