StrutsTestCase 试用手记

emu — Wed, 18 May 2005 08:19:00 GMT

junit不能��struts的action�Q�httpunit也只能测servlet。用struts作项目的时候无法方便的对action层做单元��试一直是我的心头大恨。现在好了，我们有了StrutsTestCase。按照网上的介绍�Q�StrutsTestCase用�v来应该是非常��单的�Q�只要下了jar包回来引用到工程里面��可以了。实际上可能也差不多�Q�－如果你运气不象我�q�么臭的话�?/DIV>

在sourceforge上随便挑其中一个镜象的下蝲地址�Q?BR>http://aleron.dl.sourceforge.net/sourceforge/strutstestcase/strutstest213-1.2_2.4.zip

flashget回来�Q�放到jbuilder的userhome里面�Q�找一个struts action创徏test case�Q�创建的时候吧test case的基�c�L��?MockStrutsTestCase�Q�测试的�Ҏ��一个都不用选（因�ؓ我们是要针对action的具体每一个逻辑分支��试而不是具体的某一个方法）。创建成功后��d��一个测试：

public void testSuccessfulRefresh()
{
    setRequestPathInfo("/RefreshSystemData");
    actionPerform();
    verifyForward("success");
}

嘿嘿�Q�我�_�ֿ�挑了一个没有参数的action来实验�?/P>

一切看��h��很顺利。run test�Q�噩梦开始了�Q?/P>

java.lang.NullPointerException
at servletunit.struts.MockStrutsTestCase.getActionServlet(MockStrutsTestCase.java:331)
at servletunit.struts.MockStrutsTestCase.tearDown(MockStrutsTestCase.java:130)
at hospital.tongren.oa.system.action.TestRefreshSystemDataAction.tearDown(TestRefreshSystemDataAction.java:34)
...(Click for full stack trace)...

�q�好我没有开音箱�Q�不然又是一大炮轰出来�?/P>

看来要调试了�Q�先��d��一个地方下了StrutsTestCase原码回来
http://aleron.dl.sourceforge.net/sourceforge/strutstestcase/strutstest-213-src.zip

加进userhome里面的source。debug�q�去�Q�跟到org.apache.struts.action.ActionServlet里面�Q�出错的地方是：

InputStream input =
getServletContext().getResourceAsStream("/WEB-INF/web.xml");

try {
digester.parse(input);

} catch (IOException e) {
....

input 为空指针。不知道��Z��么ServletContextSimulator在模拟ServletContext的时候没能够正确的找到webmodule的位�|�。上�|�搜了好一会儿文档�Q�在 http://strutstestcase.sourceforge.net/api/servletunit/struts/MockStrutsTestCase.html 中发��C��q�样一�D�：

NOTE: By default, the Struts ActionServlet will look for the file WEB-INF/struts-config.xml, so you must place the directory that contains WEB-INF in your CLASSPATH. ...

先照它说的试试把webmodule路径放进classpath中，没有用�?BR>往下看�Q�发��C��q�个好东东：setContextDirectory。在startup中加一句：

this.setContextDirectory(new File("E:\\projectPath\\webModulePath\\"));

�l�于把那个空指针�l�过了。但是报一个新的异常：

junit.framework.AssertionFailedError: received error 400 : Invalid path /RefreshSystemData was requested

...(Click for full stack trace)...

找不到strutsconfig里面配置的path。strutsconfig是在web.xml里面配置的，应该�q�是web.xml没找到造成的，那么��指定strutsconfig文�g的位�|�咯�Q?BR> setConfigFile("E:\\......\\struts-config.xml");

�l�于可以�q�行��h��了�?/P>

随后发现�Q�如�?nbsp; setServletConfigFile("E:\\....\\WEB-INF\\web.xml");的话MockStrutsTestCase也能够根据web.xml中的配置扑ֈ�strutsconfig文�g�?/P>

最后把上面用到的绝对地址E:\\...全部改�ؓ相对地址�Q?BR>    setContextDirectory(new File("modulePath\\"));
    setServletConfigFile("modulePath\\WEB-INF\\web.xml");
    //   this.setConfigFile("modulePath\\WEB-INF\\config\\system\\struts-config.xml");

血吐完了，�l�箋郁闷�Q��ؓ什么别人都不用配置的这么麻烦呢�Q�到底我做错了什么，�q�是jbuilder的错�Q?/P>

CactusStrutsTestCase也没配�v�Q�好像要加个什么包吧，再看看先�?/P>

用junitperf做�ƈ发测试带来的问题

用junitperf做�ƈ发测试带来的问题 
关于junitperf的一点介�l?/FONT>
junitperf 是个很小巧的java性能���试框架�Q�可以在http://sourceforge.net/project/showfiles.php?group_id=15278 上下载到。可以很�Ҏ��的把它结合junit一��h��试，比如在测试套仉���面加�q�么几行�Q?/P>
import com.clarkware.junitperf.TimedTest;
import com.clarkware.junitperf.LoadTest;
.......
    int testTimes = 10;
    int users = 5;
    suite.addTest(new TestUserDAO("test1AddUser")); //基本功能���试�Q�同时初始化环境
   
    suite.addTest(new TimedTest(new TestUserDAO("test1AddUser"), 1000)); //基本性能���试:�Ҏ��应在1�U�内完成
    suite.addTest(new LoadTest(new TestUserDAO("test1AddUser"), users)); // �q�发���试
  suite.addTest(new LoadTest(new TestUserDAO("test1AddUser"),users,testTimes)); //�q�发负蝲���试
  suite.addTest(new TimedTest(new LoadTest(new TestUserDAO("test1AddUser"),
                                           users,testTimes), 35000)); //�q�发性能���试
如果只需要反复做一个测试而不需要�ƈ发测试，可以
suite.addTest(new LoadTest(new TestUserDAO("test1AddUser"),1,testTimes)); 
当然也可以不用junitperf�Q�junit.extensions.RepeatedTest���是设计来干�q�个的：
suite.addTest(new RepeatedTest(new TestUserDAO("test1AddUser"), testTimes)); //重复���试

用junitperf做�ƈ发测试带来的问题

做�ƈ发测试的时候junitperf有一个问题。注意看�q�一行： 
new LoadTest(new TestUserDAO("test1AddUser"), users)
我们只传递了一个TestUserDAO实例�l�LoadTest�Q�却要求它开启users个线�E�来���试�Q�这栯���users个线�E�就会只针对同一个TestUserDAO实例�q�行���试。这个时候，我们在TestUserDAO里面��׃��能存放�Q何状态数据了。比如以前我很喜�Ƣ这么做�Q?/FONT>
public class TestUserDAO extends TestCase{
 private int lastId;
 protected void setUp() throws Exception{
  super.setUp();
  //构造一个测试用的数�?BR>  User user = new User("张三");
  //向数据库插入一条记�?BR>  userDAO.addUser(user);

 public void testUpdateUser() throws DaoException{
  //针对setup中插入的数据�q�行update操作
  user = userDAO.getUserById(lastId);

  userDAO.updateUser(user);
 }
 protected void tearDown() throws Exception{
  //删除���试数据
  userDAO.deleteUserById(lastId);
  super.tearDown();
 }
�q�样我是通过一个int变量lastId在各个方法之间传递被���试的数据的。如果用junitperf来测试，lastId变量��׃��被后来的�U�程覆盖�Q�导致测试失败�?BR>

解决�Ҏ��

在com.clarkware.junitperf.TestFactory的文档中对这个问题做了说明：
This factory class should be used in cases when a stateful test is intended to be decorated by a LoadTest.  A stateful test is defined as any test that defines test-specific state in its setUp() method.
TestFactory的��用方法是�q�样�Q?/P>
import com.clarkware.junitperf.TestFactory;
......
     suite.addTest(new LoadTest(new TestFactory(TestUserDAO.class), users,testTimes)); //�q�发负蝲���试
但是�q�样只能观察整个���试�cȝ��表现。如果我们要单个的测试测试类中的一个测试，那么可以考虑另一�U�方法。我们在TestFactory的文档中看到�Q?/P>
 This class is dependent on Java 2.  For earlier platforms a  local cache implementation should be changed to use, for example,  a HashMap to track thread-local information.
�q�个�Ҏ��同时也适用于我们需要处理的情况�Q?/P>
public class TestUserDAO extends TestCase{
 private static final ThreadLocal threadLocal = new ThreadLocal();
 protected void setUp() throws Exception{
  super.setUp();
  //构造一个测试用的数�?BR>  User user = new User("张三");
  //向数据库插入一条记�?BR>  userDAO.addUser(user);
  //lastId = user.getId();//刚刚插入的记录在数据库中产生的ID;
  threadLocal.set(new Integer(user.getId()));
 }
 public void testUpdateUser() throws DaoException{
  //针对setup中插入的数据�q�行update操作
  //user = userDAO.getUserById(lastId);
  user = userDAO.getUserById(((Integer)threadLocal.get()).intValue());
  user.setName("李四");
  userDAO.updateUser(user);

自作聪明的junit.swingui.TestRunner

emu — Wed, 18 May 2005 06:08:00 GMT

自作聪明的junit.swingui.TestRunner 
问题
在junit.swingui.TestRunner的时候发现TestRunner启动�q�程中报错：
log4j:ERROR A "org.apache.log4j.ConsoleAppender" object is not assignable to a "org.apache.log4j.Appender" variable.
同时也发��C��个��^时工作正常的�c�d��使用junit.swingui.TestRunner�q�行���试的时候报告一个奇怪的 ClassCastException�Q�明明构造的对象的类是实��C��指定的接口的�Q�可是就是无法造型到接口上�?BR>�q�一步研�I�发玎ͼ�即��造型回原来的�c�M��不行�Q�虽然调试的时候显�C�构造的对象���是指定的类�Q�但是就是无法造型成这个类�Q�一度认为是妖�h作祟或者机子被落了降头�?/P>
研究
求得庄老大再次出手�Q�一下指出指出问题在于不同的�c�装载器装蝲的类无法�怺�造型的。于是进去junit.swingui.TestRunner里面��L���c�装载器�Q�一���L��腾之后终于找刎ͼ�
junit.runner.BaseTestRunner
           |�Q�－�Q�－�Q�－junit.swingui.TestRunner
           |�Q�－�Q�－�Q�－junit.textui.TestRunner
在BaseTestRunner里面定义了这样一个方法：
    public TestSuiteLoader getLoader() {
        if (useReloadingTestSuiteLoader())
            return new ReloadingTestSuiteLoader();
        return new StandardTestSuiteLoader();
    }
不过注意到junit.textui.TestRunner是不会出上面的错误的�Q�因为它自己重蝲了getLoader()�Ҏ���Q?BR>    /**
     * Always use the StandardTestSuiteLoader. Overridden from
     * BaseTestRunner.
     */
    public TestSuiteLoader getLoader() {
        return new StandardTestSuiteLoader();
    }
但是junit.swingui.TestRunner���很自作聪明了，��Z��避免每次在点“run”按钮的时候装载运行器本��n�Q�就直接使用了基�cȝ���Ҏ��去获取装载器�Q�，�q�样基类���可以调用自��q��getLoader�Ҏ��来决定要启用那个classloader�Q?/P>
    public TestSuiteLoader getLoader() {
        if (useReloadingTestSuiteLoader())
            return new ReloadingTestSuiteLoader();
        return new StandardTestSuiteLoader();
    }
如果我们用sun的jdk的话�Q�这个方法会�q�回一个TestCaseClassLoader对象�Q�而这个对象在装蝲class的时候��L��调用creatLoader�Ҏ���Q?BR>    protected TestCaseClassLoader createLoader() {
        return new TestCaseClassLoader();
    }
�q�回的其实是TestCaseClassLoader。这样如果被���试�c�M��用了log4j的话�Q�会造成org.apache.log4j.Appender�c�被 sun.misc.Launcher$AppClassLoader(也就是sun.misc.Launcher�cȝ��嵌入�c�AppClassLoader)装蝲一�ơ（在启动test的过�E�中vm自动装蝲被引用到的类�Q�，然后在运行的时候又被junit.runner.TestCaseClassLoader再装载一�ơ。由两个装蝲器装载进来的�c�M�����是不是来自同一�?class文�g�Q�都会被认�ؓ是两个不同的�c�R��因此就造成了上面的错误�?BR>同样的，如果你在自己的代码里面这栯���载类�Q?BR>MyClass myClass = (MyClass)Thread.currentThread().getContextClassLoader().loadClass(mClassName);
也会造成相同的问题�ƈ抛出ClassCastException。因为MyClass是在�q�行���试的过�E�由junit.runner.TestCaseClassLoader装蝲的，而Thread.currentThread().getContextClassLoader()却指向的是sun.misc.Launcher$AppClassLoader�?/P>
解决�Ҏ��
1 java -Dlog4j.ignoreTCL junit.swingui.TestRunner
我猜TCL是ThreadClassLoader的羃写，�q�个参数的意思大概就是让log4j忽略Thread自己的类装蝲器（sun.misc.Launcher$AppClassLoader�Q�，改而��用当前Class的装载器�Q�junit.runner.TestCaseClassLoader�Q�来装蝲。但是这个方法只能解决log4j的错误报告（改变了org.apache.log4j.ConsoleAppender的装载方式）�Q�但是对我们自己写的代码中的问题却没有作用�?/P>
2 在我们自��q���c�里面写上一�D�静态代码：
  static{
        Thread.currentThread().setContextClassLoader(MyClassFactory.class.getClassLoader());
  }
和方法一�c�M���Q�这也是在工厂类中用加蝲了当前lass的装载器�Q�TestCaseClassLoader�Q�来代替Thread的初始化装蝲器sun.misc.Launcher$AppClassLoader。这个方法可以解��x��们自�׃��码中的问题，�q�且不会带来影响原来的其他代码。结合第一�U�方法可以解决上面的两个问题。但是如果你有好几个工厂�c�，或者你用的其他包里面用了这��L��装蝲方式……那你还可以试试下面的偏门：
3 注意到BaseTestRunner要进行一个useReloadingTestSuiteLoader()判断才决定返回哪个装载器
public TestSuiteLoader getLoader() {
    if (useReloadingTestSuiteLoader())
        return new ReloadingTestSuiteLoader();
    return new StandardTestSuiteLoader();
}
我们来看看这个判断过�E�：
protected boolean useReloadingTestSuiteLoader() {
    return getPreference("loading").equals("true") && !inVAJava() && fLoading;
}
嗯，里面有个inVAJava()是什么玩意儿�Q?BR>public static boolean inVAJava() {
    try {
        Class.forName("com.ibm.uvm.tools.DebugSupport");
    }
    catch (Exception e) {
        return false;
    }
    return true;
}
原来它是惛_��断如果当前��用的是ibm的虚拟机��׃��用默认装载器�Q�但是判断的条�g也忒���单了点，很容易就吧它�l�蒙�q�去了：
在当前工�E�下创徏com.ibm.uvm.tools包，在其中创建DebugSupport�c�：
package com.ibm.uvm.tools;
public class DebugSupport{}
没有错，���p��个空白的�c�，�q�样���可以把junit.swingui.TestRunner�l�蒙倒。这样做据说的副作用是，每次点run按钮的时候，都要重�vgui环境�Q�但是我没有发现有什么区别。不�q�要是没有区别，人家又干吗费那么多事呢？不解�?/P>
参考资�?/P>
