StrutsTestCase The /WEB-INF/web.xml was not found

I use StrutsTestCase2.4 under netbeans7.0 with struts1.3
When running testCase, it shows:

Error initializing action servlet
javax.servlet.UnavailableException: The /WEB-INF/web.xml was not found.

I've googled this problem and it is suggested to be solved by setContextDirectory(new File("../web"));:

protected void setUp() throws Exception
{
    super.setUp();
    setContextDirectory(new File("../web"));
 }

But I am not quite sure what the location of new File() should be.
My File tree is

My test file is under test-com-stolon-struts.

I just ran in to this. WEB-INF/web.xml (and probably struts-config.xml, etc.) must be on your classpath when the tests are running. Make sure netbeans is putting /build/web/ on the test classpath.

If you were using maven, you would add WEB-INF/*.xml as a test resource.

    <testResources>
        <testResource>
            <directory>WEB-INF</directory>
            <targetPath>/WEB-INF</targetPath>
            <includes>
                <include>*.xml</include>
            </includes>
        </testResource>
    </testResources>

回答2:

From the directory structure, it seems : setContextDirectory(new File("../../../../web"));

回答3:

So, based on the tree above, the location of new File() should be "web": protected void setUp() throws Exception { super.setUp(); setContextDirectory(new File("web")); }
