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

In general, you can define your custom request handler, and do a nasty Thread.sleep() there.

This would be possible in Restito with something like this.

Action waitSomeTime = Action.custom(input -> {
    try {
        Thread.sleep(5000);
    } catch (InterruptedException e) {
        throw new RuntimeException(e);
    }
    return input;
});

whenHttp(server).match(get("/asd"))
        .then(waitSomeTime, ok(), stringContent("Hello World"))

Not sure about Spring, however. You can easily try. Check DefaultResponseCreator for inspiration.
