Test Case taDOM2/7-taDOM2-32-AC

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

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

Behavior specified with base operations:

readCO
useCOFCE
useCOLCE

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 AC

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 AC:

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