Michael Hintenaus commented on WW-4921:
---------------------------------------
with Struts 2.5.14.1 it works fine, with Struts 2.5.15 the test will fail
{code:java}
@Action(results = @Result(location="http://struts.apache.org";, type="redirect"))
public class MyAction extends ActionSupport {
}
{code}
{code:java}
public class MyTest extends StrutsJUnit4TestCase<MyAction> {
@Test
public void test() throws Exception {
request.getSession(true);
final ActionProxy proxy = getActionProxy("/my-action.action");
final ActionInvocation invocation = proxy.getInvocation();
invocation.invoke();
assertTrue(invocation.isExecuted());
assertEquals(MyAction.SUCCESS, invocation.getResultCode());
}
}{code}
{code:java}

> Key: WW-4921
> URL: https://issues.apache.org/jira/browse/WW-4921
> Project: Struts 2
> Issue Type: Bug
> Components: Core Interceptors
> Reporter: Michael Hintenaus
> Priority: Major
> Labels: test
> Fix For: 2.5.16
>
>
> Calling
> {code:java}
> getActionProxy("/index.action").getInvocation().invoke(){code}
> in a TestCase which extends from StrutsJUnit4TestCase will lead to a
> NullPointerException.
> Overriding getActionProxy like this will help:
> {code:java}
> @Override
> protected ActionProxy getActionProxy(final String uri) {
> final ActionProxy proxy = super.getActionProxy(uri);
> final ActionContext context =
> proxy.getInvocation().getInvocationContext();
> if (context.getSession() == null) {
> context.setSession(new SessionMap<>(request));
> }
> return proxy;
> }{code}
