[Jason Vo]

Hi - I use eclipse to run this test case and point "WEB-INF" folder for classpath and I still get the error message below. could you please help me this issue? Thanks

junit 3.8.2. jar
jdk 1.6
Strut-config is located at WebRoot/WEB-INF folder.

====================
import servletunit.struts.MockStrutsTestCase;
public class LogoffActionTest extends MockStrutsTestCase {

private static final String ACTION_PATH = "/logoff";
private static final String CONTEXT_DIR = "WebRoot";

public LogoffActionTest(String arg0) {
super(arg0);
}

protected void setUp() throws Exception {
super.setUp();
setRequestPathInfo(ACTION_PATH);
setContextDirectory(new File(CONTEXT_DIR));
}

protected void tearDown() throws Exception {
super.tearDown();
}

public void testCaseForSuccessfulLogoff() {
actionPerform();
verifyForwardPath("/Logon.jsp");
}
}

--------------Error --------
servletunit.struts.ExceptionDuringTestError: A NullPointerException was thrown. This may indicate an error in your ActionForm, or it may indicate that the Struts ActionServlet was unable to find struts config file. TestCase is running from C:\Workspaces\Test\ directory. Context directory is C:\Workspaces\Test\WebRoot. struts config file must be found under the context directory, the directory the test case is running from, or in the classpath.

Well, you might be better off asking the project owner, since it's not an actual Struts product, but: is there a config file? The error message is pretty clear on what it *believes* the problem to be.

[Jason Vo]

Strut-config.xml file is located at WebRoot/WEB-INF folder and I'm not sure why it doesn't recognize the config file. From debug, i can see this line of code throw NPE

//This method is from MockStrutsTestCase class
public ActionServlet getActionServlet() {
.....
this.actionServlet.init(config); ======> NPE happened here

}

[David Newton]

Well, I don't really know anything about the framework, but the config file appears to not be in one of the three locations it mentions, no?
