Runing http call in parallel and can't receive all, Action timeout exception

Citrus Version 2.7.6

Question How to properly setup parallel test action that makes http calls and validate responses ?

What I’ve tried so far

parallel().actions(
        sendAction(),
        sendAction(),
        ...
        sendAction()
);
parallel().actions(
        receiveAction(),
        receiveAction(),
        ...
        receiveAction()
);

And even tried as below:

parallel().actions(
    sequential.actions(
        sendAction(),
        receiveAction()
    ),
    ...
    sequential.actions(
        sendAction(),
        receiveAction()
    )
);

where sendAction() is simply as below:

return http(x -> x.client(httpClient)
    .send()
    .post()
    .contentType(ContentType.APPLICATION_XML.getMimeType())
    .header("Authorization", "Basic citrus:encodeBase64('${user}:${pass}')")
    .payload(...)

receiveAction() is:

return http(x -> x.client(httpClient)
    .receive()
    .response(HttpStatus.OK)
    .validationCallback((m, c) -> {
        System.out.println(m.getPayload(String.class));
    }));

Additional information Unfortunately, it failed with timeout exception usually at 2nd or 3rd receiveAction() method call.

com.consol.citrus.exceptions.TestCaseFailedException: Action timeout while receiving synchronous reply message from http server

Running in synchronous way as below is working totally fine. But we need to run those calls in parallel.

sendAction();
receiveAction();
...
sendAction();
receiveAction();

Hi!

I knew there was a better way to solve this but I couldn’t remember instantaneously.

public class TodoListIT extends TestNGCitrusTestRunner {

    @Autowired
    private HttpClient httpClient;

    @Test
    @CitrusTest
    public void testPost() {

        final String request1 = "request1";
        final String request2 = "request2";
        final String request3 = "request3";

        parallel().actions(
                sendAction(request1),
                sendAction(request2),
                sendAction(request3));
        parallel().actions(
                receiveAction(request1),
                receiveAction(request2),
                receiveAction(request3));
    }

    public TestAction sendAction(final String requestVariable){
       return http(x -> x.client(httpClient)
                .send()
                .get()
                .extractFromHeader("citrus_message_id", requestVariable));
    }

    public TestAction receiveAction(final String requestVariable){
       return http(x -> x.client(httpClient)
                .receive()
                .response(HttpStatus.OK)
                .selector(Collections.singletonMap("citrus_message_id", "${" + requestVariable +"}"))
                .validationCallback((m, c) -> {
                    System.out.println(m.getPayload(String.class));
                }));
    }
}

You could apply selectors to identify the messages by their citrus_message_id. This is still a manual mapping. I’ll open an enhancement issue so that citrus is able to handle those situations out of the box.

Hi!

Unfortunately I can’t provide a schedule for #459 currently but it’s good to hear that the suggested solution worked for you as well.
