+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
+
+```rust
+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());

 ## Unreleased
 
+## 4.8.0
+
+### Added
+
+- Add `web::Html` responder.
+- Add `HttpRequest::full_url()` method to get the complete URL of the request.
+
+### Fixed
+
+- Always remove port from return value of `ConnectionInfo::realip_remote_addr()` when handling IPv6 addresses. from the `Forwarded` header.
+- The `UrlencodedError::ContentType` variant (relevant to the `Form` extractor) now uses the 415 (Media Type Unsupported) status code in it's `ResponseError` implementation.
+- Apply `HttpServer::max_connection_rate()` setting when using rustls v0.22 or v0.23.
+
+## 4.7.0
+
+### Added
+
+- Add `#[scope]` macro.
+- Add `middleware::Identity` type.
+- Add `CustomizeResponder::add_cookie()` method.
+- Add `guard::GuardContext::app_data()` method.
+- Add `compat-routing-macros-force-pub` crate feature which (on-by-default) which, when disabled, causes handlers to inherit their attached function's visibility.
+- Add `compat` crate feature group (on-by-default) which, when disabled, helps with transitioning to some planned v5.0 breaking changes, starting only with `compat-routing-macros-force-pub`.
+- Implement `From<Box<dyn ResponseError>>` for `Error`.
