Test Case taDOM2/34-taDOM2-7-PA

taDOM2 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:-,NSE:-,FCE:-,LCE:-]
  • LockRequest[node=PA,lock:-,PSE:-,NSE:-,FCE:EX,LCE:EX]

taDOM2 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
  • LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on PA

Operations must be incompatible
