Missing Configuration resource for Path Webroot/web-inf/struts-config.xml

Servletunit.struts.exceptionduringtesterror:a NullPointerException was thrown. This may indicate a error in your actionform, or it could indicate that struts Actionservlet is unable to find Struts  Config file.  TestCase is running from D:/workspace/struts1unittestproject directory.  Context directory has not been set.  Try calling Setcontextdirectory () with a relative or absolute path. Struts config file must be found under the context directory, the directory of the test case are running from, or in the class Path.



The approach as below:
protected void SetUp () throws Exception {
Super.setup ();
Setcontextdirectory (New File ("WebRoot"));
}
