[pgrouting-users] Problem with way restrictions in shooting star if you have more then one rule for an edge

Great! we have tested this pretty extensively but we also appreciate you 
testing and feedback. One area that we need to get better at is setting 
up a standard testing framework that we can apply before releases to 
verify that we have not broken any code. We have discussed the need for 
this, but not the details of how to do it yet.

My thinking is along the lines of we create a database of graphs, test 
cases, expected results and have a test runner that runs the test stores 
the results in a table and reports the results.

An alternative to this would be to create a collection of files that 
each represent some series of tests like the above, and can be loaded 
run evaluated, and dropped. This might be easier to manage that one huge 

It would be easy to automate the running of the tests using a Perl or 
Python script to run each test in sequence and summarize the results.

I also think that it is probably a good idea for the developers to 
create unit tests so that they can verify their code before it is 
wrapped into postgres so we can separate algorithm issues from 
integration or changes in the postgresql API that might break stuff.

Anyway if you have good simple test cases, I would love to get them and 
if you are interested in support pgRouting buy helping build some of the 
above, I would be happy to work on designing something that is easy to 
build and and maintain.

Thanks for the report.

OH and yes the last edge is always -1, but I forget the rationale for 
why at the moment.
