Test::RDF - Test RDF data for content, validity and equality, etc.
Version 0.22
use Test::RDF; is_valid_rdf($rdf_string, $syntax, 'RDF string is valid according to selected syntax'); is_rdf($rdf_string, $syntax1, $expected_rdf_string, $syntax2, 'The two strings have the same triples'); isomorph_graphs($model, $expected_model, 'The two models have the same triples'); are_subgraphs($model1, $model2, 'Model 1 is a subgraph of model 2' ); has_subject($uri_string, $model, 'Subject URI is found'); has_predicate($uri_string, $model, 'Predicate URI is found'); has_object_uri($uri_string, $model, 'Object URI is found'); has_literal($string, $language, $datatype, $model, 'Literal is found');
Use to check if the input RDF string is valid in the chosen syntax
Use to check if the input RDF strings are isomorphic (i.e. the same).
Use to check if the input RDF::Trine::Models have isomorphic graphs.
Use to check if the first RDF::Trine::Models is a subgraph of the second.
Check if the string URI passed as first argument is a subject in any of the statements given in the model given as second argument.
Check if the string URI passed as first argument is a predicate in any of the statements given in the model given as second argument.
Check if the string URI passed as first argument is a object in any of the statements given in the model given as second argument.
Check if the string passed as first argument, with corresponding optional language and datatype as second and third respectively, is a literal in any of the statements given in the model given as fourth argument.
language and datatype may not occur in the same statement, so the test fails if they are both set. If none are used, use undef, like e.g.
undef
has_literal('A test', undef, undef, $model, 'Simple literal');
A test for a typed literal may be done like
has_literal('42', undef, 'http://www.w3.org/2001/XMLSchema#integer', $model, 'Just an integer');
and a language literal like
has_literal('This is a Another test', 'en', undef, $model, 'Language literal');
Check if the string URI passed as first argument is present in any of the statements given in the model given as second argument.
Graph isomorphism is a complex problem, so do not attempt to run the isomorphism tests on large datasets. For more information see http://en.wikipedia.org/wiki/Graph_isomorphism_problem.

Michael Hendricks wrote the first Test::RDF. The present module is a complete rewrite from scratch using Gregory Todd William's RDF::Trine::Graph to do the heavy lifting.
