  Test Case taDOM3+/27-taDOM3+-26-FC
taDOM3+ Lock Requests of executed Operation insertBefore(contextNode, siblingType, siblingValue) returns NodeThe insertBefore operation is executed on the context element node CO and inserts a new previous sibling node before the context node CO. There already exists a previous sibling and the inserted new sibling node is returned.
Behavior specified with base operations:- readCO
- modifyCOPSE
- modifyPSNSE
Read Set = CO , Write Set = PSNSE COPSE - LockRequest[node=CO,lock:NR,PSE:EX,NSE:-,FCE:-,LCE:-]
- LockRequest[node=PS,lock:-,PSE:-,NSE:EX,FCE:-,LCE:-]
- LockRequest[node=PA,lock:CX,PSE:-,NSE:-,FCE:-,LCE:-]
taDOM3+ Lock Requests of checked Operation prependChild(contextElementNode, childType, childValue) executed on node FCThe prependChild operation is executed on the context element node CO and prepends 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 prepended child node (the now only child) is returned.
Bahavior specified with base operations:- readCO
