Test Case taDOM3+/2-taDOM3+-27-CO

taDOM3+ Lock Requests of executed Operation getPrevSibling(contextNode) returns Node

The getPrevSibling operation returns the previous sibling node PS of the context node CO.

Behavior specified with base operations:

  • readCO
  • useCOPSE
  • readPS
  • usePSNSE
Read Set = PS CO PSNSE COPSE , Write Set =
  • LockRequest[node=CO,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-]
  • LockRequest[node=PS,lock:NR,PSE:-,NSE:ER,FCE:-,LCE:-]

taDOM3+ Lock Requests of checked Operation insertBefore(contextNode, siblingType, siblingValue) executed on node CO

The insertBefore operation is executed on the context element node CO and inserts a new previous sibling node before the context node CO. There already exists a previous sibling and the inserted new sibling node is returned.

Bahavior specified with base operations:

  • readCO
  • modifyCOPSE
  • modifyPSNSE

Read and write sets for execution on CO:

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

Operations must be incompatible
