I need to write a junit test for a rather complex application which runs in a tomcat.

I wrote a class which builds up my spring context.

private static ApplicationContext springContext = null;

springContext = new ClassPathXmlApplicationContext( new String[] {"beans"....});

In the application there is a call:

public class myClass implements ServletContextAware {

.... final String folder = servletContext.getRealPath("/example"); ... }

which breaks everything, because the ServletContext is null.

I have started to build a mock object:

static ServletConfig servletConfigMock = createMock(ServletConfig.class);

static ServletContext servletContextMock = createMock(ServletContext.class);

@BeforeClass public static void setUpBeforeClass() throws Exception {

expect(servletConfigMock.getServletContext()).andReturn(servletContextMock).anyTimes(); expect(servletContextMock.getRealPath("/example")).andReturn("...fulllpath").anyTimes();
replay(servletConfigMock);

replay(servletContextMock);

}

Is there a simple methode to inject the ServletContext or to start the tomcat with a deployment descriptor at the runtime of the junit test?

I am using: spring, maven, tomcat 6 and easymock for the mock objects.
