Test Case taDOM2/3-taDOM2-9-CO

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 getLastChild(contextElementNode) executed on node CO

The getLastChild operation returns null because the context node CO does not have any child nodes.

Bahavior specified with base operations:

  • readCO
  • useCOLCE
  • useCOFCE

Read and write sets for execution on CO:

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

Operations must be compatible
