Test Case taDOM3+/28-taDOM3+-3-NS

taDOM3+ Lock Requests of executed Operation insertBefore(contextNode, siblingType, siblingValue) returns Node

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.

Behavior specified with base operations:

  • readCO
  • modifyCOPSE
  • modifyPAFCE
Read Set = CO , Write Set = PAFCE COPSE
  • LockRequest[node=CO,lock:NR,PSE:EX,NSE:-,FCE:-,LCE:-]
  • LockRequest[node=PA,lock:CX,PSE:-,NSE:-,FCE:EX,LCE:-]

taDOM3+ Lock Requests of checked Operation getPrevSibling(contextNode) executed on node NS

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.

Bahavior specified with base operations:

  • readCO
  • useCOPSE
  • usePAFCE

Read and write sets for execution on NS:

Read Set = NS PAFCE NSPSE , Write Set =
  • LockRequest[node=CO,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-] on NS
  • LockRequest[node=PA,lock:-,PSE:-,NSE:-,FCE:ER,LCE:-] on NS

Operations must be incompatible
