Test Case taDOM2/34-taDOM2-25-CH

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

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.

Behavior specified with base operations:

modifyPAFCE
modifyPALCE
writeCO
writeFC
writeCH
writeLC
writeDC

Read Set = , Write Set = CO FC CH LC DC CA AS AX XS PAFCE PALCE

taDOM2 Lock Requests of checked Operation prependChild(contextElementNode, childType, childValue) executed on node CH

The prependChild operation is executed on the context element node CO and prepends a new child to the (at least one) already existing child nodes. The CX lock on the context node is caused by the SX lock on the new child. The new prepended child node (the new first child) is returned.

Bahavior specified with base operations:

readCO
modifyCOFCE
modifyFCPSE

Read and write sets for execution on CH:

Read Set = CH , Write Set = CHFCE DCPSE
