Test Case taDOM2/3-taDOM2-17-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 setValue(contextElementNode, valueString) executed on node CO

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 CO:

Read Set = , Write Set = CO

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

Operations must be incompatible
