Test Case taDOM3+/8-taDOM3+-5-LC

taDOM3+ Lock Requests of executed Operation getLastChild(contextElementNode) returns Node

The getLastChild operation returns the last child LC of the context node CO.

Behavior specified with base operations:

  • readCO
  • useCOLCE
  • readLC
  • useLCNSE
Read Set = CO LC COLCE LCNSE , Write Set =
  • LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:-,LCE:ER]
  • LockRequest[node=LC,lock:NR,PSE:-,NSE:ER,FCE:-,LCE:-]

taDOM3+ Lock Requests of checked Operation getNextSibling(contextNode) executed on node LC

The getNextSibling operation returns null because the context node CO is the last child of parent node PA and no next sibling node NS exists.

Bahavior specified with base operations:

  • readCO
  • useCONSE
  • usePALCE

Read and write sets for execution on LC:

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

Operations must be compatible
