[Cactus入门]eclipse环境下，用Cactus和Jetty集成来测试Servlet

1)下载 Cactus-1.8.1
     下载 commons-codec-1.3
            
2)解压Cactus，把lib下的以下jar加入到eclipse的classpath：

cactus.core.framework.uberjar.javaEE.14-1.8.1.jar
commons-httpclient-3.1.jar
commons-logging-1.1.jar
aspectjrt-1.5.3.jar
servlet-api-2.4.jar
org.mortbay.jetty-5.1.9.jar

3)待测试类

/* 待测试类SimpleServlet.java  */

import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
public class SampleServlet extends HttpServlet {
        private static final long serialVersionUID = -4934598964259783805L;
         public boolean isAuthenticated(HttpServletRequest request){
		HttpSession session = request.getSession(false);
		if (session == null){
			return false;
		}
		String authenticationAttribute = 
			(String) session.getAttribute("authenticated");
		return Boolean.valueOf(authenticationAttribute).booleanValue();
	}

}

4)编写测试类

import org.apache.cactus.ServletTestCase;
import org.apache.cactus.WebRequest;
public class TestSampleServletIntegration extends ServletTestCase{
	private SampleServlet servlet;
	@Override
	protected void setUp(){
		servlet = new SampleServlet();
	}

	public void testIsAuthenticated(){
		session.setAttribute("authenticated", "true");
		assertTrue(servlet.isAuthenticated(request));
	}

	public void testIsNotAuthenticate(){
		assertFalse(servlet.isAuthenticated(request));
	}

	public void beginIsAuthenticateNoSession(WebRequest request){
		request.setAutomaticSession(false);
	}
	public void testISAuthenticatedNoSession(){
		assertFalse(servlet.isAuthenticated(request));
	}
}

import org.apache.cactus.extension.jetty.Jetty5xTestSetup;
import junit.framework.Test;
import junit.framework.TestCase;
import junit.framework.TestSuite;

public class TestAllWithJetty extends TestCase {

	public static Test suite(){
		System.setProperty("cactus.contextURL", "http://localhost:8080/test");
		TestSuite suite = new TestSuite("all test with Jetty");
		suite.addTestSuite(TestSampleServletIntegration.class);
		return new Jetty5xTestSetup(suite);
	}

}

    在eclipse下，以Junit方式运行 TestAllWithJetty.java ，ok看到绿条~~

注意要点：
        1.commons-httpclient包依赖commons-code.jar,否则运行时会抛出异常：
java.lang.NoClassDefFoundError: org/apache/commons/codec/DecoderException
2.Cactus和Jetty集成时,在TestAllWithJetty测试类，返回的test case应该是Jetty5xTestSetup,若返回Jetty6xTestSetup运行会出现找不到类的错误, 导入的Jetty包若用最新的jetty-6.1.15.jar，运行时也会出现错误，用Cactus lib自带的org.mortbay.jetty-5.1.9.jar,看来目前的Cactus版本不支持Jetty6
PS：例子来自<Junit in action>的第8章
