  Test Case taDOM3+/24-taDOM3+-7-AC
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 getFirstChild(contextElementNode) executed on node ACThe getFirstChild operation returns null because the context node CO does not have any child nodes.
Bahavior specified with base operations:Read and write sets for execution on AC:Read Set = AC , Write Set = - LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:ER,LCE:ER] on AC
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:-,NSE:-,FCE:ER,LCE:ER] on AC | Requested lock NR on AC compatible to existing lock IX.
