Test Case taDOM3/1-taDOM3-23-DC

taDOM3 Lock Requests of executed Operation getParentNode(contextNode) returns Node

The getParentNode operation returns the parent node PA of the context node CO.

Behavior specified with base operations:

readCO
readPA

Read Set = PA CO , Write Set =

LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-]
LockRequest[node=PA,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-]

taDOM3 Lock Requests of checked Operation appendChild(contextElementNode, childType, childValue) executed on node DC

The 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

Operations must be compatible
