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

chunjihong

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
