arborium-test-harness

Test harness for arborium grammar crates.

Purpose

Provides utilities for testing tree-sitter grammars and their highlight/injection queries.

Usage

In your grammar crate's tests:

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

    #[test]
    fn test_grammar() {
        arborium_test_harness::test_grammar(
            language(),
            "rust",
            HIGHLIGHTS_QUERY,
            INJECTIONS_QUERY,
            LOCALS_QUERY,
        );
    }
}

The harness validates that:

• The grammar compiles correctly
• Highlight queries are syntactically valid
• Injection queries parse without errors
