SPARQL smith

Latest Version Released API docs Crates.io downloads actions status Gitter

sparql-smith is a test case generator for the SPARQL language.

It provides a single struct, Query that could be serialized to a SPARQL query using to_string().

The queries generated are sadly not always valid. Variables scopes are not properly handled yet. All SPARQL features are not supported yet.

The DATA_TRIG constant is provided as an example dataset on which queries could be evaluated.

Usage example with libfuzzer-sys and spargebra:

use libfuzzer_sys::fuzz_target;

fuzz_target!(|data: sparql_smith::Query| {
    spargebra::Query::parse(&data.to_string(), None).unwrap()
