Test Case taDOM2+/7-taDOM2+-28-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 insertBefore(contextNode, siblingType, siblingValue) executed on node AC

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 AC:

Read Set = AC , Write Set =

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

Operations must be compatible
