Struts 2 : StrutsTestCase and SessionAware action

[Ville Korhonen]

Hi,
I'am trying to test sessionAware action with strutstestcase but I get NullPointerException while trying to insert stuff into the session. It seems that interceptor inserts null into the action's session. Has someone solved the problem or is there some kind of work around?

Not enough information to help--is there a session map?

[Ville Korhonen]

Hope this helps. Struts core and struts-junit-plugin are version 2.1.8.1

Example login action class:

public class TestAction extends ActionSupport implements SessionAware{
    private String username;
    private Map<String, Object> session;
    
    public void setUsername(String username){this.username = username;}
    public String getUsername(){return username;}
    public void setSession(Map<String, Object> session) {
        this.session = session;
    }
    public String execute(){
        if(getUsername() == null || "".equals(getUsername())){
            return INPUT;
        }
        else{
            session.put("foo", "bar");
            return SUCCESS;
        }
    }
}

Test class for action class. First test passes but second one throws nullpointerexception in session.put("foo", "bar"); -line.

  public class TestTestAction extends StrutsTestCase{

    public void testNull() throws Exception{
        ActionProxy proxy = getActionProxy("/test/test.action");
        String result = proxy.execute();
        assertEquals("input", result);
    }

    public void testSuccess() throws Exception{
        request.setParameter("username", "test");
        ActionProxy proxy = getActionProxy("/test/test.action");
        String result = proxy.execute();
        assertEquals("success", result);
    }
}

Are you sure that running through the action proxy execute simulates an entire request?

I found the solutions from dicital sanctum. I was lazy and thought that execute method would do everything for me Thanks for help.
Here is the code if someone else needs it

   
    public void testSuccess() throws Exception{
        Map<String, Object> session = new HashMap<String, Object>();
        request.setParameter("username", "test");
        ActionProxy proxy = getActionProxy("/test/test.action");
        ActionContext actionContext = proxy.getInvocation().getInvocationContext();
        actionContext.setSession(session);
        String result = proxy.execute();
        assertEquals("success", result);
        Map<String, Object> sessionAfter = actionContext.getSession();
        assertEquals("bar", sessionAfter.get("foo"));
    }
