* @summary Tests the functionality of IIOMetadataNode.setAttributeNode().
* Four separate tests are involved:
* 1) Tests whether a DOMException.INUSE_ATTRIBUTE_ERR is thrown if newAttr
* is already an attribute of another Element object.
* 2) Tests whether setAttributeNode() returns the old attribute if it is
* replaced.
* 3) Tests whether setAttributeNode() returns null if the new attribute is
* not replacing an existing attribute.
* 4) Tests whether the new attribute successfully replaces an existing one.
