Test Case taDOM2+/3-taDOM2+-6-PA

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 getFirstChild(contextElementNode) executed on node PA

The getFirstChild operation returns the first child FC of the context node CO.

Bahavior specified with base operations:

readCO
useCOFCE
readFC
useFCPSE

Read and write sets for execution on PA:

Read Set = PA PS PAFCE , Write Set =

LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:ER,LCE:-] on PA
LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on PA
LockRequest[node=FC,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-] on PA
LockRequest[node=FN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on PA
