Test Case taDOM2/9-taDOM2-32-CO

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 CO

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

Bahavior specified with base operations:

modifyPAFCE
modifyNSPSE
writeCO
writeFC
writeCH
writeLC
writeDC

Read and write sets for execution on CO:

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