//! 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());
//! }
//! ```
