Test Case taDOM3+/28-taDOM3+-7-PA

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 getFirstChild(contextElementNode) executed on node PA

The getFirstChild operation returns null because the context node CO does not have any child nodes.

Bahavior specified with base operations:

  • readCO
  • useCOFCE
  • useCOLCE

Read and write sets for execution on PA:

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

Operations must be incompatible
