  Test Case taDOM3+/3-taDOM3+-25-PA
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 prependChild(contextElementNode, childType, childValue) executed on node PAThe prependChild operation is executed on the context element node CO and prepends a new child to the (at least one) already existing child nodes. The CX lock on the context node is caused by the SX lock on the new child. The new prepended child node (the new first child) is returned.
Bahavior specified with base operations:- readCO
- modifyCOFCE
- modifyFCPSE
Read and write sets for execution on PA:Read Set = PA , Write Set = PAFCE - LockRequest[node=CO,lock:NRCX,PSE:-,NSE:-,FCE:EX,LCE:-] on PA
- LockRequest[node=FC,lock:-,PSE:EX,NSE:-,FCE:-,LCE:-] on PA
