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: test_config.rs
    path of file: ./repos/feroxbuster/tests
    
    the code of the file until where you have to start completion: mod utils;
use assert_cmd::prelude::*;
use httpmock::MockServer;
use predicates::prelude::*;
use std::process::Command;
use utils::{setup_tmp_directory, teardown_tmp_directory};

#[test]
/// send a single valid request, expect a 200 response
fn read_in_config_file_for_settin
    
fn read_in_config_file_for_settings() -> Result<(), Box<dyn std::error::Error>> {
    let srv = MockServer::start();

    let (tmp_dir, file) = setup_tmp_directory(&["threads = 37".to_string()], "ferox-config.toml")?;

    Command::cargo_bin("feroxbuster")
        .unwrap()
        .current_dir(&tmp_dir)
        .arg("--url")
        .arg(srv.url("/"))
        .arg("--wordlist")
        .arg(file.as_os_str())
        .arg("-vvvv")
        .assert()
        .success()
        .stderr(predicate::str::contains("â”‚ 37"));

    teardown_tmp_directory(tmp_dir);

    Ok(())
}
