Crate camel_component_mock 

camel-component-mock

Mock component for rust-camel — testing utility that records received exchanges for later assertion, useful for verifying route output in tests.

Main types: MockComponent, MockEndpoint, MockProducer, MockExpectations.

Example

use camel_component_mock::MockComponent;
use camel_component_api::{Component, NoOpComponentContext, Exchange, Message};

// Create a mock component and endpoint
let component = MockComponent::new();
let endpoint = component
    .create_endpoint("mock:result", &NoOpComponentContext)
    .unwrap();

// In a real route, the producer would be used as a Tower service.
// After sending exchanges, you can inspect them:
let inner = component.get_endpoint("result").unwrap();
// inner.assert_exchange_count(1).await;
// inner.exchange(0).assert_body_text("hello");

expectedCount is inert in the live runtime path

The expectedCount URI parameter records intent only: at first endpoint creation it registers an exact count expectation on the endpoint inner. It is enforced only when an explicit assertion method runs (assert_satisfied / try_assert_satisfied), never by the live producer — poll_ready and call do not consult it. Under camel run, where no test caller invokes assertions, expectedCount never rejects or drops traffic.

Structs

ExchangeAssert

A handle for making synchronous assertions on a recorded exchange.

MockComponent

The Mock component is a testing utility that records every exchange it receives via its producer. It exposes helpers to inspect and assert on the recorded exchanges.

MockConfig

Configuration for MockComponent.

MockEndpoint

A mock endpoint that records all exchanges sent to it.

MockEndpointInner

The actual data behind a mock endpoint. Shared across all MockEndpoint instances created with the same name via MockComponent.

MockExpectations

Expectations set on a mock endpoint for batch-style assertion.

Enums

MockAssertionError

Error returned by MockEndpointInner::try_assert_satisfied when a recorded expectation is not satisfied (or is malformed).
