Test Case taDOM3+/7-taDOM3+-14-AX

taDOM3+ 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]

taDOM3+ Lock Requests of checked Operation getValue(contextAttrNode) executed on node AX

The getValue operation executed on the attribute context node CA of an arbitrary element node CO returns the string node AS appended to the attribute node that represents the actual node value.

Bahavior specified with base operations:

readCA
readAS

Read and write sets for execution on AX:

Read Set = AX XS , Write Set =

LockRequest[node=CA,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on AX
LockRequest[node=AS,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on AX

Operations must be compatible

Check	Existing LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:ER,LCE:ER] with Requested LockRequest[node=CA,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on AX	Requested lock IR on AC compatible to existing lock IR. Requested lock IR on PA compatible to existing lock IR. Requested lock IR on CO compatible to existing lock NR.	Compatible
Check	Existing LockRequest[node=CO,lock:NR,PSE:-,NSE:-,FCE:ER,LCE:ER] with Requested LockRequest[node=AS,lock:NR,PSE:-,NSE:-,FCE:-,LCE:-] on AX	Requested lock IR on AC compatible to existing lock IR. Requested lock IR on PA compatible to existing lock IR. Requested lock IR on CO compatible to existing lock NR.	Compatible
