Crate tower_async_test 

This crate is to be used to test tower_async_layer::Layers, by helping you write tests to guarantee this.

The guarantees that it test are:

• the tower_async_service::Service wrapped by the tower_async_layer::Layer receives the expected requests, and that your layer react as expected on the sent responses or errors.
• the tower_async_layer::Layer sends back the expected response or error.

It does so by providing a crate::Builder that you can use to define the test flow and expectations. It does this by a generated crate::mock::Mock tower_async_service::Service that is used as the core tower_async_service::Service to help you test your own tower_async_layer::Layers with the crate::mock::Mock tower_async_service::Service.

The crate::mock::Mock service cannot be used directly, but is instead use automatically for any test spawned using the crate::Builder and specifically its crate::Builder::test method.

Examples

use tower_async_test::Builder;
use tower_async_layer::Identity;

#[tokio::main]
async fn main() {
    Builder::new("ping")
        .send_response("pong")
        .expect_request("ping")
        .test(Identity::new())
        .await
        .expect_response("pong");
}

Re-exports

Modules

builder

Builder for creating crate::mock::Mock services and testing them with a tower_async_layer::Layer.

mock

This module provides the Mock tower_async_service::Service that is used by this crate as the core tower_async_service::Service to help you test your own tower_async_layer::Layers.
