Please conduct these tests before you turnin your program, to make sure that you have coded correctly. These 2 tests can be conducted once you have run the family.clp file from the Jess shell prompt using the "(batch ./family.clp)" command. Then do "(batch ./test1.clp)" and "(batch ./test2.clp)" to conduct these tests (in proper order - test1 followed by test2).

 

Test 1 - test1.clp

This test can be conducted by adding an additional relevant fact (Kimberley is the daughter of Leo):

(assert (gender Kimberley female))
(assert (father Leo Kimberley))

(watch facts)
(run)


and testing new inferences. 15 new facts should be inferred (if you did not use any of your own predicates!). They are:

(MAIN::sister Kimberley Wendy)
(MAIN::sister Wendy Kimberley)
(MAIN::daughter Kimberley Leo)
(MAIN::niece Kimberley Gerald)
(MAIN::grandmother Grace Kimberley)
(MAIN::uncle Gerald Kimberley)
(MAIN::granddaughter Kimberley Grace)
(MAIN::greatuncle Paul Kimberley)
(MAIN::cousin Michelle Kimberley)
(MAIN::cousin Kimberley Michelle)
(MAIN::greataunt Harriet Kimberley)
(MAIN::cousin Marsha Kimberley)
(MAIN::cousin Kimberley Marsha)
(MAIN::greatgrandmother Jenny Kimberley)
(MAIN::greatgranddaughter Kimberley Jenny)





Test2 - test2.clp

This test involved testing with an additional query (who are the nieces?):

% define the query for finding whoever are whoever's niece's
(defquery find-nieces "find nieces" (niece ?X ?Y))

% run the query find-nieces
(bind ?it (run-query find-nieces))

% print out the results by iterating
(printout t "Who are nieces?" crlf)
(while(?it hasNext) (bind ?token (call ?it next))
(bind ?fact (call ?token fact 1)) 
(bind ?slot (fact-slot-value ?fact __data))
(bind ?datum1 (nth$ 1 ?slot))
(bind ?datum2 (nth$ 2 ?slot))
(printout t ?datum1 " is the niece of " ?datum2 ". " crlf))
(printout t " " crlf)



It should print 5 facts:

Kimberley is the niece of Gerald. 
Wendy is the niece of Gerald. 
Marsha is the niece of Leo. 
Michelle is the niece of Leo. 
Megan is the niece of Michelle.
