Test Case taDOM3+/28-taDOM3+-4-DC

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 getNextSibling(contextNode) executed on node DC

The getNextSibling operation returns the next sibling node NS of the context node CO.

Bahavior specified with base operations:

  • readCO
  • useCONSE
  • readNS
  • useNSPSE

Read and write sets for execution on DC:

Read Set = DC DCNSE DCPSE , Write Set =
  • LockRequest[node=CO,lock:NR,PSE:-,NSE:ER,FCE:-,LCE:-] on DC
  • LockRequest[node=NS,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-] on DC

Operations must be compatible
