Test Case taDOM2/5-taDOM2-24-PS

taDOM2 Lock Requests of executed Operation getNextSibling(contextNode) returns null value

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.

Behavior specified with base operations:

  • readCO
  • useCONSE
  • usePALCE
Read Set = CO PALCE CONSE , Write Set =
  • LockRequest[node=CO,lock:NR,PSE:-,NSE:ER,FCE:-,LCE:-]
  • LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-]
  • LockRequest[node=PA,lock:-,PSE:-,NSE:-,FCE:-,LCE:ER]

taDOM2 Lock Requests of checked Operation appendChild(contextElementNode, childType, childValue) executed on node PS

The appendChild operation is executed on the context element node CO and appends a new child. The context element node CO has still no child nodes before this operation. 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 now only child) is returned.

Bahavior specified with base operations:

  • readCO
  • modifyCOFCE
  • modifyCOLCE

Read and write sets for execution on PS:

Read Set = PS , Write Set =
  • LockRequest[node=CO,lock:CX,PSE:-,NSE:-,FCE:EX,LCE:EX] on PS
  • LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on PS

Operations must be compatible
