Testing rest api launching rocket without codegen

[Ks89]

I've an application with a main like this

#[rocket::main]
async fn main() -> Result<(), rocket::Error> {
    let _rocket = rocket::build()
        .mount("/keepalive", ........)
        .launch()
        .await?;

    Ok(())
}

then I've an integration test for 'keepalive' api like this:

#[rocket::async_test]
async fn keepalive() {
    let client: Client = Client::tracked(rocket()).await.unwrap();

    let req: LocalRequest = client.get("/keepalive");
    let res: LocalResponse = req.dispatch().await;
    assert_eq!(res.status(), Status::Ok);
    assert_eq!(res.into_json::<Value>().await.unwrap(), json!({ "alive": true }));
}

however this doesn't work because rocket() is not defined:

error[E0423]: expected function, found crate `rocket`
 --> src/tests_integration/keepalive.rs:9:42
  |
9 |     let client: Client = Client::tracked(rocket()).await.unwrap();
  |                                          ^^^^^^ not a function

If I change the test code in this way:

#[rocket::async_test]
async fn keepalive() {
    let rocket = rocket::build();
    let client: Client = Client::tracked(rocket()).await.unwrap();

    let req: LocalRequest = client.get("/keepalive");
    let res: LocalResponse = req.dispatch().await;
    assert_eq!(res.status(), Status::Ok);
    assert_eq!(res.into_json::<Value>().await.unwrap(), json!({ "alive": true }));
}

it will result in a 404 because that rest api is not defined.

Which is the right way to test my rocket REST api in this case?

Thanks.
