cactus and servlet redirection

Show all headers | View raw

hi,
I have a servlet for adding books to a booksdb and another for listing
books.I am trying to use cactus for testing.

In the beginPostMethod(..) of testcase ,I created parameters needed
for creating a Book and a Publisher,and added them to WebRequest
instance.
testPostMethod() of testcase merely creates a BookAddServlet and calls
doPost()on it.
In doPost(..) of BookAddServlet,after a Book and a Publisher are
created ,the response.sendRedirect() is called to invoke
BookListServlet's doGet() method.
BookListServlet's doGet() method gets a list of books from booksdb and
adds them to request.Then using RequestDispatcher
 forwards to booklist.jsp.
It is the endPostMethod(..) where I am having a problem.
I want to test if after creating a book ,the booklist jsp page is
properly displayed.

I am using endPostMethod(com.meterware.httpunit.WebResponse response)
to make use of httpunit's WebResponse class.
Here ,I am getting response.getResponseCode() as 302.I don't get the
title string of booklist.jsp(which is "allBooks") when
I try response.getTitle().I only get an empty string.
Is this because the doGet() of BookList servlet is invoked in between?
Can someone comment on it?How do I test whether the response is
properly redirected to the correct jsp page?

thanks in advance
jim

web.xml maps the servlets as below
..
   <servlet>
    <servlet-name>booklistservlet</servlet-name>
    <servlet-class>bookshop.servlets.BookListServlet</servlet-class>
   </servlet>

   <servlet-mapping>
     <servlet-name>booklistservlet</servlet-name>
     <url-pattern>/booklistservlet</url-pattern>
   </servlet-mapping>

   <servlet>
    <servlet-name>addbookservlet</servlet-name>
    <servlet-class>bookshop.servlets.BookAddServlet</servlet-class>
   </servlet>

   <servlet-mapping>
     <servlet-name>addbookservlet</servlet-name>
     <url-pattern>/createbook</url-pattern>
   </servlet-mapping>
   ...

BookAddServlet.java
package bookshop.servlets;
...
public class BookAddServlet extends HttpServlet {
	private BookDaoImpl bookdaoimpl =BookDaoImpl.getInstance();
	private PublisherDaoImpl pubdaoimpl =PublisherDaoImpl.getInstance();

	public void doGet(HttpServletRequest request, HttpServletResponse
response)throws ServletException, IOException {
		RequestDispatcher dispatcher =
request.getRequestDispatcher("bookadd.jsp");
		List<Publisher> publishers = pubdaoimpl.findAllPublishers();
		request.setAttribute("publishers",publishers);
		dispatcher.forward(request, response);
	}
	public void doPost(HttpServletRequest request, HttpServletResponse
response)throws ServletException, IOException {
		String isbn = request.getParameter("isbn");
		String publisherName = request.getParameter("publishername");

		Book book = new Book();
		book.setIsbn(Long.parseLong(isbn));
		Publisher publisher = new Publisher();
		publisher.setName(publisherName);
		book.setPublisher(publisher);
		bookdaoimpl.saveOrUpdateBook(book);//publisher will be saved since
it is so configured in hibernate

		response.sendRedirect("booklistservlet");//which calls get method of
BookListServlet

	}
	private Date parseDate(String publishDate) {
		try {
			Date dt = new SimpleDateFormat("yyyy/MM/dd").parse(publishDate);
			return dt;
		} catch (ParseException e) {
			return null;
		}
	}
}

BookListServlet.java

package bookshop.servlets;
...
public class BookListServlet extends HttpServlet {
	private BookDaoImpl bookdaoimpl =BookDaoImpl.getInstance();
	public void doGet(HttpServletRequest request, HttpServletResponse
response)throws ServletException, IOException {
		List books = bookdaoimpl.findAllBooks();
		request.setAttribute("books", books);
		RequestDispatcher dispatcher =
request.getRequestDispatcher("booklist.jsp");
		dispatcher.forward(request, response);
	}
}


Now I want to test using cactus and httpunit these two servlets

package bookshop.test.cactus.servlet;

import org.apache.cactus.ServletTestCase;
import org.apache.cactus.WebRequest;
public class BookAddServletTests extends ServletTestCase{
	private BookAddServlet bookaddservlet;
	public BookAddServletTests(String theName) {
		super(theName);
	}
	public void beginPostMethod(WebRequest theRequest){
		String isbn = "1111";
		String publisherName = "amazon";
		theRequest.addParameter("isbn", isbn);
		theRequest.addParameter("publishername", publisherName);
	}

	public void testPostMethod() throws ServletException, IOException{
		 BookAddServlet bookaddservlet = new BookAddServlet();
		 bookaddservlet.doPost(this.request, this.response);
	}

	public void endPostMethod(com.meterware.httpunit.WebResponse
response) throws SAXException{
		assertEquals("response should be redirected",
302,response.getResponseCode());
		String responseTitle = response.getTitle();
		//this is where I have doubts..response should be redirected finally
to booklist.jsp which has a title "allBooks"
		assertEquals("response title should be
allBooks","allBooks",responseTitle);
	}

}
