You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: spec_test.rs
    path of file: ./repos/tools/crates/rome_json_formatter/tests
    
    the code of the file until where you have to start completion: use rome_formatter_test::spec::{SpecSnapshot, SpecTestFile};
use rome_json_formatter::context::JsonFormatOptions;
use std::path::Path;

mod language {
    include!("language.rs");
}

/// [insta.rs](https://insta.rs/docs) snapshot testing
///
/// For better development workflow, run
/// `cargo watch -i '*.new' -x 'test -p rome_js_formatter formatter'`
///
/// To review and commit the snapshots, 
    
pub fn run(spec_input_file: &str, _expected_file: &str, test_directory: &str, _file_type: &str) {
    let root_path = Path::new(concat!(env!("CARGO_MANIFEST_DIR"), "/tests/specs/"));

    let Some(test_file) = SpecTestFile::try_from_file(spec_input_file, root_path) else { return; };

    let options = JsonFormatOptions::default();
    let language = language::JsonTestFormatLanguage::default();

    let snapshot = SpecSnapshot::new(test_file, test_directory, language, options);

    snapshot.test()
