Test Case taDOM3+/5-taDOM3+-31-PS

taDOM3+ 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=PA,lock:-,PSE:-,NSE:-,FCE:-,LCE:ER]

taDOM3+ Lock Requests of checked Operation deleteNode(contextNode) executed on node PS

The deleteNode operation is executed on the context element node CO (an arbitrary child of PA) and deletes the context node. Previous and next sibling nodes are existing.

Bahavior specified with base operations:

modifyPSNSE
modifyNSPSE
writeCO
writeFC
writeCH
writeLC
writeDC

Read and write sets for execution on PS:

Read Set = , Write Set = PS COPSE
