Test Case taDOM2/31-taDOM2-34-DC

taDOM2 Lock Requests of executed Operation deleteNode(contextNode) returns nothing

The deleteNode operation is executed on the context element node CO (an arbitrary child of PA) and deletes the context node. Previous and next sibling nodes are existing.

Behavior specified with base operations:

modifyPSNSE
modifyNSPSE
writeCO
writeFC
writeCH
writeLC
writeDC

Read Set = , Write Set = CO FC CH LC DC CA AS AX XS PSNSE NSPSE

taDOM2 Lock Requests of checked Operation deleteNode(contextNode) executed on node DC

The deleteNode operation is executed on the context element node CO and deletes the context node. Thereby, the context node is the only child of its parent node.

Bahavior specified with base operations:

modifyPAFCE
modifyPALCE
writeCO
writeFC
writeCH
writeLC
writeDC

Read and write sets for execution on DC:

Read Set = , Write Set = DC DCFCE DCLCE
