Test Case taDOM2/5-taDOM2-23-PA

taDOM2 Lock Requests of executed Operation getNextSibling(contextNode) returns null value

The getNextSibling operation returns null because the context node CO is the last child of parent node PA and no next sibling node NS exists.

Behavior specified with base operations:

readCO
useCONSE
usePALCE

Read Set = CO PALCE CONSE , Write Set =

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

taDOM2 Lock Requests of checked Operation appendChild(contextElementNode, childType, childValue) executed on node PA

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 PA:

Read Set = PA , Write Set = PALCE

LockRequest[node=CO,lock:CX,PSE:-,NSE:-,FCE:-,LCE:EX] on PA
LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on PA
LockRequest[node=LC,lock:-,PSE:-,NSE:EX,FCE:-,LCE:-] on PA
