  Test Case taDOM3+/3-taDOM3+-23-DC
taDOM3+ Lock Requests of executed Operation getPrevSibling(contextNode) returns null valueThe getPrevSibling operation returns null because the context node CO is the first child of parent node PA and no previous sibling node PS exists.
Behavior specified with base operations:Read Set = CO PAFCE COPSE , Write Set = - LockRequest[node=CO,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-]
- LockRequest[node=PA,lock:-,PSE:-,NSE:-,FCE:ER,LCE:-]
taDOM3+ Lock Requests of checked Operation appendChild(contextElementNode, childType, childValue) executed on node DCThe appendChild operation is executed on the context element node CO and appends a new child to the (at least one) already existing child nodes. The CX resp. NRCX lock on the context node is caused by the SX lock on the new child. The new appended child node (the new last child) is returned.
Bahavior specified with base operations:- readCO
- modifyCOLCE
- modifyLCNSE
Read and write sets for execution on DC:Read Set = DC , Write Set = DCLCE DCNSE - LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:-,LCE:EX] on DC
- LockRequest[node=LC,lock:-,PSE:-,NSE:EX,FCE:-,LCE:-] on DC
