Use Session and Request Scope Beans in Tests with Spring

Sometimes it is useful haven the Web Scopes in Unit Tests. Usually Spring just show this very useful error in the Unit Test:

Caused by: java.lang.IllegalStateException: No Scope registered for scope 'session'
	at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:334)
	at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:194)
	at org.springframework.beans.factory.support.DefaultListableBeanFactory.findAutowireCandidates(DefaultListableBeanFactory.java:1120)
	at org.springframework.beans.factory.support.DefaultListableBeanFactory.doResolveDependency(DefaultListableBeanFactory.java:1044)
	at org.springframework.beans.factory.support.DefaultListableBeanFactory.resolveDependency(DefaultListableBeanFactory.java:942)
	at org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor$AutowiredFieldElement.inject(AutowiredAnnotationBeanPostProcessor.java:533)
	... 28 common frames omitted

You can easily have all needed web scopes in your unit test by adding the following annotation to your Tests: @WebAppConfiguration.

Now Web Scopes like:

@Bean(name = "foo") @Scope("session")
public String getString()

will work.
