NAME
    Test::FITesque::RDF - Formulate Test::FITesque fixture tables in RDF

SYNOPSIS
      my $suite = Test::FITesque::RDF->new(source => $file)->suite;
      $suite->run_tests;

    See `t/integration-basic.t` for a full test script example.

DESCRIPTION
    This module enables the use of Resource Description Framework to describe
    fixture tables. It will take the filename of an RDF file and return a
    Test::FITesque::Suite object that can be used to run tests.

    The RDF serves to identify the implementation of certain fixtures, and can
    also supply parameters that can be used by the tests, e.g. input
    parameters or expectations. See Test::FITesque for more on how the
    fixtures are implemented.

  ATTRIBUTES AND METHODS
    This module implements the following attributes and methods:

    `source`
        Required attribute to the constructor. Takes a Path::Tiny object
        pointing to the RDF file containing the fixture tables. The value will
        be converted into an appropriate object, so a string can also be
        supplied.

    `suite`
        Will return a Test::FITesque::Suite object, based on the RDF data
        supplied to the constructor.

    `transform_rdf`
        Will return an arrayref containing tests in the structure used by
        Test::FITesque::Test. Most users will rather call the `suite` method
        than to call this method directly.

    `base_uri`
        A IRI to use in parsing the RDF fixture tables to resolve any relative
        URIs.

  RDF EXAMPLE
    The below example starts with prefix declarations. Since this is a
    pre-release, some of the prefixes are preliminary examples. Then, the
    tests in the fixture table are listed explicitly. Only tests mentioned
    using the `test:fixtures` predicate will be used. Tests may be an RDF
    List, in which case, the tests will run in the specified sequence, if not,
    no sequence may be assumed.

    Then, two test fixtures are declared. The `test:handler` predicate is used
    to identify the class containing implementations, while `dc:identifier` is
    used to name the function within that class.

    The `test:params` predicate is used to link the parameters that will be
    sent as a hashref into the function. The key of the hashref will be the
    local part of the predicate used in the description (i.e. the part after
    the colon in e.g. `my:all`). It is up to the test writer to mint the URIs
    of the parameters, and the `param_base` is used to set indicate the
    namespace, so that the local part can be resolved, if wanted. The
    resolution itself happens in URI::NamespaceMap.
