---+ Testing the SPARQL 1.1 implementation

---++ Preparation

First, the test-cases are provided as a git module. To install them, use

  ==
  % git submodule update --init test/Tests/sparql-1.1
  ==

---++ Running the test cases

To run the test suite, run

  ==
  % swipl test_sparql.pl
  ?- run_query_tests.
  ==

It is possible to  zoom  into   a  particular  test  using query_test/1,
providing the test name as argument. E.g.,

  ==
  ?- query_test('(pp23) Diamond, with tail -- :p+').
  =============== BEGIN '(pp23) Diamond, with tail -- :p+' ===============
  % Parsed "data-diamond-tail.ttl" in 0.00 sec; 5 triples
  true.
  ==

See the module header for more useful predicates to diagnose issues.
