Struct TestClient 

pub struct TestClient<A: Application> { /* private fields */ }

An in-process HTTP test client that dispatches requests directly through an Application without opening a TCP socket.

Use this in unit and integration tests to exercise controllers and routing without starting the server.

Example

use rust_web_server::app::App;
use rust_web_server::core::New;
use rust_web_server::test_client::TestClient;

let client = TestClient::new(App::new());

let res = client.get("/healthz").send();
assert_eq!(200, res.status());

let res = client.post("/echo")
    .header("Content-Type", "text/plain")
    .body_text("hello")
    .send();
assert_eq!(200, res.status());

Implementations

impl<A: Application> TestClient<A>

pub fn new(app: A) -> Self

Create a test client wrapping app. Requests are dispatched on a synthetic 127.0.0.1:12345 → 127.0.0.1:7878 connection.

pub fn get(&self, path: &str) -> TestRequest<'_, A>

Build a GET request to path.

pub fn post(&self, path: &str) -> TestRequest<'_, A>

Build a POST request to path.

pub fn put(&self, path: &str) -> TestRequest<'_, A>

Build a PUT request to path.

pub fn patch(&self, path: &str) -> TestRequest<'_, A>

Build a PATCH request to path.

pub fn delete(&self, path: &str) -> TestRequest<'_, A>

Build a DELETE request to path.

pub fn options(&self, path: &str) -> TestRequest<'_, A>

Build an OPTIONS request to path.
