RDF/SPARQL Test Suite Executor

rdf-test-suite (current stable version 2.1.5) is a robust JavaScript/TypeScript command-line tool and library designed for executing W3C RDF and SPARQL test suites against any compatible JavaScript-based engine. It is actively maintained, with a development focus on broad test suite compatibility and modularity. Key differentiators include its support for a wide array of specifications such as SPARQL 1.0/1.1, RDF/XML, N-Triples, N-Quads, Turtle, TriG, JSON-LD (1.0/1.1), RDFa, Microdata, N3, and RDF-star/SPARQL-star, with a clear roadmap for expanding coverage. The tool itself functions as a runner, requiring users to provide their own JavaScript implementation of an RDF parser or SPARQL query engine that adheres to specific TypeScript interfaces (e.g., `IQueryEngine`, `IParser`) depending on the test suite being executed. It can output human-readable results to the console or machine-readable EARL reports for compliance tracking. Its modular architecture facilitates easy extension for new test cases or report formats.
