This test returns a failure for a block diagram node matching any name specified in the test configuration:
For example, if you specify names of "Add" and "Subtract", then any Add or Subtract functions in a VI will be returned as a failure. This test is useful for detecting all the instances of a particular node type in a large set of VIs.
Note that this test uses the "Style" property of the Node class to make the match. The "Style" of a node is almost always the name of the object as it appears in Quick Drop/the palettes.
