Struts2.3.12 junit4 testcase request & session are null

问题


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 :

回答1:


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.

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




回答3:


To avoid request from being null:

request = new MockHttpServletRequest();

For session:

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