How to mock a session in Spring 4 Java based config for unit test?

Question

So I have a session scoped bean and naturally, I'm getting the error you would expect in my unit tests.

java.lang.IllegalStateException: No Scope registered for scope 'Session'

What is the proper Java based way to mock a session for a unit test?

This was the old way:

Spring Test session scope bean using Junit

The thing is though that I don't need to test a controller. I'm testing a component with a session scoped bean in it. I just need a fake session so that it works.

Answer 1

It was this easy :-/

In the test:

public void setup() throws Exception {
            ConfigurableBeanFactory factory = (ConfigurableBeanFactory) wac.getAutowireCapableBeanFactory();
            factory.registerScope("session", new SessionScope());
    }

Then you call that before every test that needs it. Could just use @Before if you are using JUnit.
