Test Case taDOM3+/7-taDOM3+-34-PA

taDOM3+ Lock Requests of executed Operation getFirstChild(contextElementNode) returns null value

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

Behavior specified with base operations:

  • readCO
  • useCOFCE
  • useCOLCE
Read Set = CO COFCE COLCE , Write Set =
  • LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:ER,LCE:ER]

taDOM3+ Lock Requests of checked Operation deleteNode(contextNode) executed on node PA

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.

Bahavior specified with base operations:

  • modifyPAFCE
  • modifyPALCE
  • writeCO
  • writeFC
  • writeCH
  • writeLC
  • writeDC

Read and write sets for execution on PA:

Read Set = , Write Set = PA PS CO NS CS FC CH LC DC CA AS AX XS
  • LockRequest[node=CO,lock:SX,PSE:EX,NSE:EX,FCE:-,LCE:-] on PA
  • LockRequest[node=PA,lock:-,PSE:-,NSE:-,FCE:EX,LCE:EX] on PA

Operations must be incompatible
