Test Case taDOM3+/3-taDOM3+-3-CO

taDOM3+ 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=PA,lock:-,PSE:-,NSE:-,FCE:ER,LCE:-]

taDOM3+ Lock Requests of checked Operation getPrevSibling(contextNode) executed on node CO

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.

Bahavior specified with base operations:

  • readCO
  • useCOPSE
  • usePAFCE

Read and write sets for execution on CO:

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

Operations must be compatible

CheckExisting LockRequest[node=CO,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-]
with
Requested LockRequest[node=CO,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-] on CO		Requested lock IR on AC compatible to existing lock IR.
Requested lock IR on PA compatible to existing lock IR.
Requested lock NR on CO compatible to existing lock NR.
On CO the previous sibling edge lock ER is compatible to the requested ER
