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: process_smoke.rs
    path of file: ./repos/phaser/phaser/vendor/tokio/tests
    
    the code of the file until where you have to start completion: #![warn(rust_2018_idioms)]
#![cfg(feature = "full")]

use tokio::process::Command;
use tokio_test::assert_ok;

#[tokio::test]
async fn simple() {
    let mut cmd;

    if cfg!(windows) {
        cmd = Command::new("cmd");
        cmd.arg("/c");
    } else {
        cmd = Command::new("sh");
       
    
async fn simple() {
    let mut cmd;

    if cfg!(windows) {
        cmd = Command::new("cmd");
        cmd.arg("/c");
    } else {
        cmd = Command::new("sh");
        cmd.arg("-c");
    }

    let mut child = cmd.arg("exit 2").spawn().unwrap();

    let id = child.id().expect("missing id");
    assert!(id > 0);

    let status = assert_ok!(child.wait().await);
    assert_eq!(status.code(), Some(2));

    // test that the `.wait()` method is fused just like the stdlib
    let status = assert_ok!(child.wait().await);
    assert_eq!(status.code(), Some(2));

    // Can't get id after process has exited
    assert_eq!(child.id(), None);
    drop(child.kill());
}
