Test Case taDOM2/9-taDOM2-17-AC

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

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

Behavior specified with base operations:

  • readCO
  • useCOLCE
  • useCOFCE
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 setValue(contextElementNode, valueString) executed on node AC

The setValue operation executed on the context element node CO returns the modified context element itself. In taDOM2(+) the CX lock on PA must be requested additionally in order to prevent an execution of the getChildNodes() method on the parent node.

Bahavior specified with base operations:

  • writeCO

Read and write sets for execution on AC:

Read Set = , Write Set = AC
  • LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on AC
  • LockRequest[node=CN,lock:SX,PSE:-,NSE:-,FCE:-,LCE:-] on AC
  • LockRequest[node=PA,lock:CX,PSE:-,NSE:-,FCE:-,LCE:-] on AC

Operations must be compatible
