Test Case taDOM2/9-taDOM2-31-PA

taDOM2 Lock Requests of executed Operation getLastChild(contextElementNode) returns null value

The getLastChild operation returns null because the context node CO does not have any child nodes.

Behavior specified with base operations:

readCO
useCOLCE
useCOFCE

Read Set = CO COFCE COLCE , Write Set =

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

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

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 PA:

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