Citrus-Framework: Conditional validation depending on status code

I'm evaluating citrus-framework for blackbox testing of a rest service.

is there a way with the java DSL and the conditional container todo a validation depending of status code?

       http(httpActionBuilder -> httpActionBuilder
                .client(sutClient)
                .receive()
                .response()
                .messageType(MessageType.JSON)
                .extractFromPayload("$.", "operationReponse")
                .extractFromHeader(HttpMessageHeaders.HTTP_STATUS_CODE, "statusCode"));

        conditional().when("${statusCode} = 200").actions(
                // how to validate on ${operationResponse} ??
                .validate("$.field1", "${expectedUUID}")
                .validate("$.elements[0].result", "APPROVED")
        );

        conditional().when("${statusCode} = 301").actions(
                // how to extract from a variable ${operationResponse}  ?? 
                extractFromPayload("$.pollUrl", "idToGet");
                http(hab -> hab.client(sutClient).send().get("/v1/myendpoint"));
                http(hab -> hab.client(sutClient).receive().response(HttpStatus.OK)
                .messageType(MessageType.JSON)
                .validate("$.field1", "${expectedUUID}")
                .validate("$.elements[0].result", "APPROVED")

        );

eventually would like to create a behavior for reuse on different test cases.

Solution

What you need here is to store the received Http response into the local message store for later validation. Instead of extracting the payload to a variable you can add a name for the received message:

http(httpActionBuilder -> httpActionBuilder
                .client(sutClient)
                .receive()
                .response()
                .messageType(MessageType.JSON)
                .name("operationResponse")
                .extractFromHeader(HttpMessageHeaders.HTTP_STATUS_CODE, "statusCode"));

You can access the named message content later in further test steps then.

echo("citrus:message(helloMessage.payload())")

For more complex logic I would add a custom test action and access the message store to load the message by its name:

action(new AbstractTestAction() {
    @Override
    public void doExecute(TestContext context) {
        // do something with stored message
        Message message = context.getMessageStore().getMessage("operationResponse"); 
    }
})

By the way I have spotted a typo in your sample code where you use "operationReponse" and "operationResponse".
