Molecule Difference Checker

Perform a difference check on any molecule compatible input columns. If the tables in the input do not match in terms of column types, names or row count then this node will fail. This node will also fail immediately it encounters molecules in the matching rows between the inputs that do not match. This node is designed to be used as part of the automated test system.

Options

Fail on First Error:

If selected and a difference is found between the molecules in port 1 and port 2 the node will immediately stop and throw an exception. This is useful for testing systems. For an actual comparison view of the content unselect this option.

Input Ports

Datatable with the output of the node to test.

The "golden" (i.e. correct example) datatable.

Output Ports

Datatable with the output of the node to test with the checked molecule columns removed.

The "golden" (i.e. correct example) datatable with the checked molecule columns removed.
