Test Case taDOM2/7-taDOM2-25-NS

taDOM2 Lock Requests of executed Operation getFirstChild(contextElementNode) returns null value

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

Behavior specified with base operations:

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

taDOM2 Lock Requests of checked Operation prependChild(contextElementNode, childType, childValue) executed on node NS

The prependChild operation is executed on the context element node CO and prepends a new child to the (at least one) already existing child nodes. The CX lock on the context node is caused by the SX lock on the new child. The new prepended child node (the new first child) is returned.

Bahavior specified with base operations:

  • readCO
  • modifyCOFCE
  • modifyFCPSE

Read and write sets for execution on NS:

Read Set = NS , Write Set =
  • LockRequest[node=CO,lock:CX,PSE:-,NSE:-,FCE:EX,LCE:-] on NS
  • LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on NS
  • LockRequest[node=FC,lock:-,PSE:EX,NSE:-,FCE:-,LCE:-] on NS

Operations must be compatible
