well done Sean! I am also glad to see one more SquishQL/RDQL 
implementation appearing out there :)

there are is a ref to Libby's testing repository into the 
"Implementations" section of the rdfqr page

http://swordfish.rdfweb.org/rdfquery/tests/

she bundled together her SquishQL conjunctive tests, RDQL jena and 
rdfstore ones - there are some README files in there which should help 
you to set up and run your python tests. All tests assume bArcs are 
allowed and bNodes are being used to flag binding vars into input query 
N-Triple-patterns for simplicity.

at the moment, mine and Libby's attempts (see repository) are simply 
trying to check the query parsers/engines and count the number of 
results - Andy is doing more using jena graph equality/isomorphism 
stuff on returned sub-graphs. Some basic interoperability seems 
possible. More ideas or suggestions are welcome

cheers
