Test Case taDOM3+/34-taDOM3+-8-PA

taDOM3+ Lock Requests of executed Operation deleteNode(contextNode) returns nothing

The deleteNode operation is executed on the context element node CO and deletes the context node. Thereby, the context node is the only child of its parent node.

Behavior specified with base operations:

  • modifyPAFCE
  • modifyPALCE
  • writeCO
  • writeFC
  • writeCH
  • writeLC
  • writeDC
Read Set = , Write Set = CO FC CH LC DC CA AS AX XS PAFCE PALCE
  • LockRequest[node=CO,lock:SX,PSE:EX,NSE:EX,FCE:-,LCE:-]
  • LockRequest[node=PA,lock:-,PSE:-,NSE:-,FCE:EX,LCE:EX]

taDOM3+ Lock Requests of checked Operation getLastChild(contextElementNode) executed on node PA

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

Bahavior specified with base operations:

  • readCO
  • useCOLCE
  • readLC
  • useLCNSE

Read and write sets for execution on PA:

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

Operations must be incompatible
