Test Case taDOM2+/3-taDOM2+-28-CO

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 insertBefore(contextNode, siblingType, siblingValue) executed on node CO

The insertBefore operation is executed on the context element node CO and inserts a new previous sibling node before the context node CO. There does not exist a previous sibling, so the context element node was the first child of the parent node PA and the inserted new sibling node (the new first child of PA) is returned.

Bahavior specified with base operations:

readCO
modifyCOPSE
modifyPAFCE

Read and write sets for execution on CO:

Read Set = CO , Write Set = PAFCE COPSE

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