  Test Case taDOM3/24-taDOM3-28-CO
taDOM3 Lock Requests of executed Operation appendChild(contextElementNode, childType, childValue) returns NodeThe appendChild operation is executed on the context element node CO and appends a new child. The context element node CO has still no child nodes before this operation. 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 now only child) is returned.
Behavior specified with base operations:- readCO
- modifyCOFCE
- modifyCOLCE
Read Set = CO , Write Set = COFCE COLCE - LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:EX,LCE:EX]
taDOM3 Lock Requests of checked Operation insertBefore(contextNode, siblingType, siblingValue) executed on node COThe insertBefore operation is executed on the context element node CO and inserts a new previous sibling node before the context node CO. There does not exist a previous sibling, so the context element node was the first child of the parent node PA and the inserted new sibling node (the new first child of PA) is returned.
Bahavior specified with base operations:- readCO
- modifyCOPSE
- modifyPAFCE
Read and write sets for execution on CO:Read Set = CO , Write Set = PAFCE COPSE - LockRequest[node=CO,lock:NR,PSE:EX,NSE:-,FCE:-,LCE:-] on CO
- LockRequest[node=PA,lock:CX,PSE:-,NSE:-,FCE:EX,LCE:-] on CO
Operations must be compatible| Check | Existing LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:EX,LCE:EX]
with
Requested LockRequest[node=CO,lock:NR,PSE:EX,NSE:-,FCE:-,LCE:-] on CO | Requested lock IR on AC compatible to existing lock IX.
Requested lock IR on PA compatible to existing lock IX.
Requested lock NR on CO compatible to existing lock NRCX.
