Struts2.3.12 junit4 testcase request & session are null

Question

I have already gone through this solution : Struts 2 JUnit Plugin v2.2.3: Test Class Extending StrutsTestCase; 'request' is null

But I'm already not having struts2-spring plugin, and neither I'm using spring in my application.

I have 3 test-cases, 2 fails at request being null and one fails at session being null

First Stacktrace

java.lang.NullPointerException
    at org.apache.struts2.interceptor.MessageStoreInterceptor.before(MessageStoreInterceptor.java:228)
    at org.apache.struts2.interceptor.MessageStoreInterceptor.intercept(MessageStoreInterceptor.java:193)
    at com.opensymphony.xwork2.DefaultActionInvocation.invoke(DefaultActionInvocation.java:246)
    at org.apache.struts2.impl.StrutsActionProxy.execute(StrutsActionProxy.java:54)
    at actions.TestIoOptimizationAction.login(TestIoOptimizationAction.java:29)

corresponds to

            Collection actionErrors = (Collection) session.get(actionErrorsSessionKey);

Second & Third test stacktrace

java.lang.NullPointerException
    at org.apache.struts2.impl.StrutsActionProxy.getErrorMessage(StrutsActionProxy.java:69)
    at com.opensymphony.xwork2.DefaultActionProxy.prepare(DefaultActionProxy.java:185)
    at org.apache.struts2.impl.StrutsActionProxy.prepare(StrutsActionProxy.java:63)
    at org.apache.struts2.impl.StrutsActionProxyFactory.createActionProxy(StrutsActionProxyFactory.java:39)
    at com.opensymphony.xwork2.DefaultActionProxyFactory.createActionProxy(DefaultActionProxyFactory.java:58)
    at org.apache.struts2.StrutsJUnit4TestCase.getActionProxy(StrutsJUnit4TestCase.java:149)

corresponds to

        String contextPath = ServletActionContext.getRequest().getContextPath();

I believe there is some dependency issues. I've tried removing a few dependencies one-by-one and in-combination, but neither worked.

Here's how my POM looks like :

Update - The tests looks like

@Test
public void login() throws Exception {
    request.setParameter("email", "nitin.cool4urchat@gmail.com");
    request.setParameter("password", "22");
    ActionProxy proxy = getActionProxy("login");
    String result = proxy.execute();
    assertEquals("success", result);
    System.out.println(response.getContentAsString());
}

@Test
public void testView() throws Exception {
    ActionProxy proxy = getActionProxy("/optimize/view");
    String result = proxy.execute();
    assertEquals("success", result);
    System.out.println(response.getContentAsString());

    proxy = getActionProxy("/optimize/view/23");
    result = proxy.execute();
    assertEquals("success", result);
    System.out.println(response.getContentAsString());

    proxy = getActionProxy("/optimize/view/110");
    result = proxy.execute();
    assertEquals("success", result);
    System.out.println(response.getContentAsString());
}

@Test
public void testSave() throws Exception {
    request.setContent("{\"id\":\"1\",\"name\":\"nitin\"}".getBytes());
    request.addHeader("Content-Type", "application/json");
    request.setMethod("POST");

    ActionProxy proxy = getActionProxy("/save");
    actions.IoOptimizationAction myAct = (actions.IoOptimizationAction) proxy.getAction();

    String result = proxy.execute();

    assertEquals("success", result);
    System.out.println(response.getContentAsString());
}

UPDATE I changed the test to executeAction as suggested & hence, the 2nd test now looks like

 @Test
    public void testView() throws Exception {
        System.out.println(ActionContext.getContext());
        System.out.println(executeAction("optimize/view"));
}

The error stacktrace is :

If you are using getActionProxy method to execute your actions then you need to set new session map into the invocation context.

ActionProxy actionProxy = getActionProxy("/action");
Map<String, Object> sessionMap = new HashMap<String, Object>();
actionProxy.getInvocation().getInvocationContext().setSession(sessionMap);
actionProxy.execute();

If you don't need reference to action proxy then you can use executeAction method. Note that executeAction will return actual output of the result, not the result returned from execute method.

is there an alternative to `getActionProxy` ? – coding_idiot Oct 29 '13 at 08:56
I finally used the getActionProxy() and the session error seems to gone, but the request error : NPE at `String contextPath = ServletActionContext.getRequest().getContextPath();` is still there. – coding_idiot Oct 29 '13 at 09:05
I tried both `executeAction` and `getActionProxy` for the testView() test, but neither worked, both gave NPE for request – coding_idiot Oct 29 '13 at 09:09
Can you verify what is null? Does `ActionContext.getContext()` returns context? Maybe it is some interceptor issue. – Aleksandr M Oct 29 '13 at 09:17
`System.out.println(ActionContext.getContext()); System.out.println(executeAction("optimize/view"));` - Prints not null for getContext() – coding_idiot Oct 29 '13 at 09:21
In the html reponse, I see the NPE but in Netbeans Output I see - [2013-10-29 14:50:38.766] [ WARN] MockServletContext.getRealPath:298 - Couldn't determine real path of resource class path resource [org/apache/struts2/dispatcher/error_en_US.ftl] java.io.FileNotFoundException: class path resource [org/apache/struts2/dispatcher/error_en_US.ftl] cannot be resolved to URL because it does not exist – coding_idiot Oct 29 '13 at 09:22
please see the updated question, it has the complete stack-trace – coding_idiot Oct 29 '13 at 09:25
Maybe you have some error in your action, check if getting the context path leads to error or something else does. – Aleksandr M Oct 29 '13 at 09:28

To avoid request from being null:

request = new MockHttpServletRequest();

For session:

Map<String, Object> sessionMap = new HashMap<String, Object>();
actionProxy.getInvocation().getInvocationContext().setSession(sessionMap);

In my case I needed to call super.setUp from my test.
