Test Case taDOM3+/3-taDOM3+-31-DC

taDOM3+ Lock Requests of executed Operation getPrevSibling(contextNode) returns null value

The 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:

readCO
useCOPSE
usePAFCE

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 deleteNode(contextNode) executed on node DC

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 DC:

Read Set = , Write Set = DC DCNSE DCPSE
