Test Case taDOM3/33-taDOM3-23-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 last child of its parent node.

Behavior specified with base operations:

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

taDOM3 Lock Requests of checked Operation appendChild(contextElementNode, childType, childValue) executed on node PA

The appendChild operation is executed on the context element node CO and appends a new child to the (at least one) already existing child nodes. The CX resp. NRCX lock on the context node is caused by the SX lock on the new child. The new appended child node (the new last child) is returned.

Bahavior specified with base operations:

  • readCO
  • modifyCOLCE
  • modifyLCNSE

Read and write sets for execution on PA:

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

Operations must be incompatible
