Test Case taDOM3+/3-taDOM3+-2-DC

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 DC

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

Bahavior specified with base operations:

  • readCO
  • useCOPSE
  • readPS
  • usePSNSE

Read and write sets for execution on DC:

Read Set = DC DCNSE DCPSE , Write Set =
  • LockRequest[node=CO,lock:NR,PSE:ER,NSE:-,FCE:-,LCE:-] on DC
  • LockRequest[node=PS,lock:NR,PSE:-,NSE:ER,FCE:-,LCE:-] on DC

Operations must be compatible
