Testing example doesn't work about actix-website HOT 3 CLOSED

"unit tests" cannot be used to test handlers that use macro-based routing.

I recommend always using "integration tests" for handlers. Will leave this issue open since it's not clear in the docs.

from actix-website.

I've struggled with this when reading the tutorial.

It starts us off with the attribute macro that specifies the url:

#[get("/")]
async fn hello() -> impl Responder {
    HttpResponse::Ok().body("Hello world!")
}

And to build the app you do this:

#[actix_web::main]
async fn main() -> std::io::Result<()> {
    HttpServer::new(|| {
        App::new()
            .service(hello)
    })
    .bind(("127.0.0.1", 8080))?
    .run()
    .await
}

I've then skipped ahead to the testing section where you have unit tests and integration tests. Per searching around the internet (and this issue), unit tests are not suitable for use with the attribute macro.

However, neither is the current integration code snippet in the docs. You have to change the way the app is built up:

#[cfg(test)]
mod tests {
    use actix_web::{http::header::ContentType, test, web, App};

    use super::*;

    #[actix_web::test]
    async fn test_index_get() {
        let app = test::init_service(App::new().service(index)).await;
        let req = test::TestRequest::default()
            .insert_header(ContentType::plaintext())
            .to_request();
        let resp = test::call_service(&app, req).await;
        assert!(resp.status().is_success());
    }
}

Notice we call .service(index), instead of .route("/", web::get().to(index)).

I do like the routing attribute macros, as I'm coming over from Flask.

reworked some wording in c5a9579

• less precedence put on unit tests
• integration tests use routing macro setups
