Spring 3 - Testing a controller @Autowired Servlet Context

Question

I have a controller with the following annotation

@Autowired
ServletContext servletContext;

which seems to work fine and to autowired the servlet context properly. However when I try to run the junit I get the following exception:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'ControllerTest': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: javax.servlet.ServletContext

The strange issue is that this only happened with ServletContext, I have other beans autowired on this particular controller and unit tests works fine for those.

Any advice would be very helpful.

Answer 1

As @bluefoot states, you should use MockServletContext. For this to work, instead of auto wiring the ServletContext, you can implement ServletContextAware. Spring will notice this when running in a web application context and inject the ServletContext and in the JUnit test you can call the setServletContext method to set the MockServletContext.

Answer 2

Well, your're not supposed to have a real ServletContext inside a junit test ambient.

You should use MockServletContext.
