Crate arborium_test_harness 

Test harness for arborium grammar crates.

This crate provides utilities for testing tree-sitter grammars and their queries.

Usage

#[cfg(test)]
mod tests {
    use super::*;

    #[test]
    fn test_grammar() {
        arborium_test_harness::test_grammar(
            language(),
            "rust",
            HIGHLIGHTS_QUERY,
            INJECTIONS_QUERY,
            LOCALS_QUERY,
            env!("CARGO_MANIFEST_DIR"),
