Test Case taDOM2+/3-taDOM2+-30-DC

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 insertAfter(contextNode, siblingType, siblingValue) executed on node DC

The insertAfter operation is executed on the context element node CO and inserts a new next sibling node after the context node CO. There does not exist a next sibling, so the context element node was the last child of the parent node PA and the inserted new sibling node (the new last child of PA) is returned.

Bahavior specified with base operations:

readCO
modifyCONSE
modifyPALCE

Read and write sets for execution on DC:

Read Set = DC , Write Set = DCLCE DCNSE

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