MockRestServiceServer simulate backend timeout in integration test

Question

I am writing some kind of integration test on my REST controller using MockRestServiceServer to mock backend behaviour. What I am trying to achieve now is to simulate very slow

Answer 1

If you control timeout in your http client and use for example 1 seconds you can use mock server delay

new MockServerClient("localhost", 1080)
.when(
    request()
        .withPath("/some/path")
)
.respond(
    response()
        .withBody("some_response_body")
        .withDelay(TimeUnit.SECONDS, 10)
);

If you want to drop connection in Mock Server use mock server error action

new MockServerClient("localhost", 1080)
.when(
    request()
        .withPath("/some/path")
)
.error(
    error()
        .withDropConnection(true)
);
