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: build.rs
    path of file: ./repos/wasm-pack/tests/all
    
    the code of the file until where you have to start completion: use crate::utils;
use assert_cmd::prelude::*;
use std::fs;
use std::path::Path;

#[test]
fn build_in_non_crate_director
    
fn it_should_not_make_a_pkg_json_if_passed_no_pack() {
    let fixture = utils::fixture::js_hello_world();
    fixture
        .wasm_pack()
        .arg("build")
        .arg("--no-pack")
        .assert()
        .success();

    let pkg_path = fixture.path.join("pkg");
    assert_eq!(pkg_path.join("package.json").exists(), false);
    assert_eq!(pkg_path.join("README.md").exists(), false);
    assert_eq!(pkg_path.join("licence").exists(), false);
}
