Test Case taDOM2/3-taDOM2-34-LC

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

The getPrevSibling operation returns null because the context node CO is the first child of parent node PA and no previous sibling node PS exists.

Behavior specified with base operations:

  • readCO
  • useCOPSE
  • usePAFCE
Read Set = CO PAFCE COPSE , Write Set =
  • LockRequest[node=CO,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-]
  • LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-]
  • LockRequest[node=PA,lock:-,PSE:-,NSE:-,FCE:ER,LCE:-]

taDOM2 Lock Requests of checked Operation deleteNode(contextNode) executed on node LC

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 LC:

Read Set = , Write Set = LC DC COFCE COLCE
  • LockRequest[node=CO,lock:SX,PSE:-,NSE:-,FCE:-,LCE:-] on LC
  • LockRequest[node=PA,lock:-,PSE:-,NSE:-,FCE:EX,LCE:EX] on LC

Operations must be compatible
