Test Case taDOM3+/6-taDOM3+-3-FC

taDOM3+ Lock Requests of executed Operation getFirstChild(contextElementNode) returns Node

The getFirstChild operation returns the first child FC of the context node CO.

Behavior specified with base operations:

  • readCO
  • useCOFCE
  • readFC
  • useFCPSE
Read Set = CO FC COFCE FCPSE , Write Set =
  • LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:ER,LCE:-]
  • LockRequest[node=FC,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-]

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

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 FC:

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

Operations must be compatible
