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: prettier_tests.rs
    path of file: ./repos/biome/crates/biome_css_formatter/tests
    
    the code of the file until where you have to start completion: use std::{env, path::Path};

use biome_css_formatter::context::CssFormatOptions;
use biome_for
    
fn test_snapshot(input: &'static str, _: &str, _: &str, _: &str) {
    countme::enable(true);

    let root_path = Path::new(concat!(
        env!("CARGO_MANIFEST_DIR"),
        "/tests/specs/prettier/"
    ));

    let test_file = PrettierTestFile::new(input, root_path);
    let options = CssFormatOptions::default()
        .with_indent_style(IndentStyle::Space)
        .with_indent_width(2.into());
    let language = language::CssTestFormatLanguage::default();
    let snapshot = PrettierSnapshot::new(test_file, language, options);

    snapshot.test()
}
