Struct RestHarness 

pub struct RestHarness { /* private fields */ }

Mounts a router and exercises the real pipeline: routing, extractors, middlewares and guards, validation, and error mapping.

let harness = RestHarness::new(UserController::register_routes(&container, Router::new()));

let response = harness.get("/users/1").send().await;
assert_eq!(response.status, 200);
assert_eq!(response.json::<User>().name, "Ada");

Implementations

impl RestHarness

pub fn new(router: Router) -> Self

pub fn with_header( &self, name: impl Into<String>, value: impl Into<String>, ) -> Self

A client that sends name: value on every request — a bearer token, an API key, a tenant header.

Returns a new harness rather than mutating: a test usually wants both the authenticated and the anonymous client, and comparing them is the point.

pub fn with_bearer(&self, token: impl Display) -> Self

A client authenticating with Authorization: Bearer ….

pub fn with_cookie(&self, name: &str, value: impl Display) -> Self

A client sending the token in a cookie, for a guard configured to read one.

pub fn get(&self, path: &str) -> RequestBuilder

pub fn post(&self, path: &str) -> RequestBuilder

pub fn put(&self, path: &str) -> RequestBuilder

pub fn delete(&self, path: &str) -> RequestBuilder

pub fn request(&self, method: &str, path: &str) -> RequestBuilder

Trait Implementations

impl Clone for RestHarness

fn clone(&self) -> RestHarness

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
