lib.rs:

Integration testing tools for Actix Web applications.

The main integration testing tool is [TestServer]. It spawns a real HTTP server on an unused port and provides methods that use a real HTTP client. Therefore, it is much closer to real-world cases than using init_service, which skips HTTP encoding and decoding.

Examples

use actix_web::{get, web, test, App, HttpResponse, Error, Responder};

#[get("/")]
async fn my_handler() -> Result<impl Responder, Error> {
    Ok(HttpResponse::Ok())
}

#[actix_rt::test]
async fn test_example() {
    let srv = actix_test::start(||
        App::new().service(my_handler)
    );

    let req = srv.get("/");
    let res = req.send().await.unwrap();

    assert!(res.status().is_success());
}
