Test Case taDOM2+/3-taDOM2+-34-PA

taDOM2+ 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=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-]
LockRequest[node=PA,lock:-,PSE:-,NSE:-,FCE:ER,LCE:-]

taDOM2+ Lock Requests of checked Operation deleteNode(contextNode) executed on node PA

The deleteNode operation is executed on the context element node CO and deletes the context node. Thereby, the context node is the only child of its parent node.

Bahavior specified with base operations:

modifyPAFCE
modifyPALCE
writeCO
writeFC
writeCH
writeLC
writeDC

Read and write sets for execution on PA:

Read Set = , Write Set = PA PS CO NS CS FC CH LC DC CA AS AX XS
