Example 6 with ConnectionPool

use of com.hotels.styx.client.connectionpool.ConnectionPool in project styx by ExpediaGroup.

the class StyxHostHttpClientTest method ignoresCancelledHeaders.

@Test
public void ignoresCancelledHeaders() {
    // Request observable unsubscribe/cancel has to be ignored after "onNext" event.
    // This is because Reactor Mono will automatically cancel after an event has
    // been published.

    ConnectionPool pool = mockPool(connection);
    Context context = mockContext();
    AtomicReference<LiveHttpResponse> transformedResponse = new AtomicReference<>();
    StyxHostHttpClient hostClient = new StyxHostHttpClient(pool);
    // The StepVerifier consumes the response event and then unsubscribes
    // from the response observable.
    StepVerifier.create(hostClient.sendRequest(request, context)).consumeNextWith(transformedResponse::set).verifyComplete();
    // The response is still alive...
    verify(pool, never()).returnConnection(any(Connection.class));
    verify(pool, never()).closeConnection(any(Connection.class));
    // ... until response body is consumed:
    transformedResponse.get().consume();
    // Finally, the connection is returned after the response body is fully consumed:
    verify(pool).returnConnection(any(Connection.class));
