The WG is not at a point yet where we have started an up-to-date test 
repo. A while ago we merely discussed the format that we want to use. 
Meanwhile, in case it helps, you may want to look at the tests at

     https://github.com/TopQuadrant/shacl/tree/master/src/test

the format of these tests is described here

     http://datashapes.org/testcases.html

(This is not the current draft for official tests or test format, but 
it's close)
