Test JS objects as NodeFilters.

On success, you will see a series of "PASS" messages, followed by "TEST COMPLETE".


Testing with raw function filter
 filtering node A1
PASS walker.firstChild(); walker.currentNode.id is 'A1'
 filtering node B1
 filtering node B2
PASS walker.nextNode(); walker.currentNode.id is 'B2'

Testing with object filter
 filtering node A1
PASS walker.firstChild(); walker.currentNode.id is 'A1'
 filtering node B1
 filtering node B2
PASS walker.nextNode(); walker.currentNode.id is 'B2'

Testing with null filter
PASS walker.firstChild(); walker.currentNode.id is 'A1'
PASS walker.nextNode(); walker.currentNode.id is 'B1'

Testing with undefined filter
PASS walker.firstChild(); walker.currentNode.id is 'A1'
