Test Case taDOM2/7-taDOM2-8-AC

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 getLastChild(contextElementNode) executed on node AC

The getLastChild operation returns the last child LC of the context node CO.

Bahavior specified with base operations:

readCO
useCOLCE
readLC
useLCNSE

Read and write sets for execution on AC:

Read Set = AC PA , Write Set =

LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:-,LCE:ER] on AC
LockRequest[node=CN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on AC
LockRequest[node=LC,lock:NR,PSE:-,NSE:ER,FCE:-,LCE:-] on AC
LockRequest[node=LN,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on AC

Operations must be compatible
