Struct TestClient 

pub struct TestClient { /* private fields */ }

Test client for integration testing without network binding

TestClient wraps a RustApi instance and allows sending simulated HTTP requests through the full middleware and handler pipeline.

Implementations

impl TestClient

pub fn new(app: RustApi) -> Self

Create a new test client from a RustApi instance

Example

let app = RustApi::new().route("/", get(handler));
let client = TestClient::new(app);

pub fn with_body_limit(app: RustApi, limit: usize) -> Self

Create a new test client with custom body limit

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

Send a GET request

Example

let response = client.get("/users").await;

pub async fn post_json<T: Serialize>( &self, path: &str, body: &T, ) -> TestResponse

Send a POST request with JSON body

Example

let response = client.post_json("/users", &CreateUser { name: "Alice" }).await;

pub async fn request(&self, req: TestRequest) -> TestResponse

Send a request with full control

Example

let response = client.request(
    TestRequest::put("/users/1")
        .header("Authorization", "Bearer token")
        .json(&UpdateUser { name: "Bob" })
).await;
