Test Case taDOM2/34-taDOM2-5-CO

taDOM2 Lock Requests of executed Operation deleteNode(contextNode) returns nothing

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.

Behavior specified with base operations:

modifyPAFCE
modifyPALCE
writeCO
writeFC
writeCH
writeLC
writeDC

Read Set = , Write Set = CO FC CH LC DC CA AS AX XS PAFCE PALCE

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

taDOM2 Lock Requests of checked Operation getNextSibling(contextNode) executed on node CO

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.

Bahavior specified with base operations:

readCO
useCONSE
usePALCE

Read and write sets for execution on CO:

Read Set = CO PALCE CONSE , Write Set =

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

Operations must be incompatible
