Test Case taDOM2+/3-taDOM2+-5-DC

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 getNextSibling(contextNode) executed on node DC

The getNextSibling operation returns null because the context node CO is the last child of parent node PA and no next sibling node NS exists.

Bahavior specified with base operations:

  • readCO
  • useCONSE
  • usePALCE

Read and write sets for execution on DC:

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

Operations must be compatible
