Junit4和jmock如何进行正确测试问题总结



1. 最近在补充AT案例的时候，遇到异常的分支。本着程序员认真负责的态度，觉得应该也要把异常测试一下，于是上网搜索了一下

   https://unmi.cc/junit-4-how-to-test-exceptions/

2. 使用工具:jUnit4,主要使用了如下方法，

   @Test

         public void testHandleProcessEx()

         {

                  ServiceRequest request = newServiceRequest();

                  List<CheckResultDTO> list =new ArrayList<CheckResultDTO>();

                  list.add(new CheckResultDTO());

                  list.add(new CheckResultDTO());

                  request.setParameter(CFSCheckNames.REJECT,list);

                 

                  Throwable t = null;

                  try

                  {

                            enrollInputRejectHandler.handleProcess(request);

                  }

                  catch(Exception e)

                  {

                            t = e;

                  }

                 

                  Assert.assertNotNull(t);

                  Assert.assertTrue(t instanceofIllegalArgumentException);

                  Assert.assertTrue(t.getMessage().contains("只能有一种拒绝条件！rejects:2"));

3. 单元测试之Mock技术，Junit结合Mock测试，会发现Eclipse自带的juint和jmock测试异常的时候

    

   报
   java.lang.SecurityException: class "org.hamcrest.TypeSafeMatcher"'ssigner information does not match signer information of other classes in thesame package。

    

   添加的时候，注意把JUnit4的order放到最后。因为junit4它自己带了一个Hamcrest jar。
   classpath配置如下：

<classpathentrykind="lib" path="lib/jmock-2.5.1.jar"/>

         <classpathentry kind="lib"path="lib/jmock-junit3-2.5.1.jar"/>

         <classpathentry kind="lib"path="lib/jmock-junit4-2.5.1.jar"/>

         <classpathentry kind="lib"path="lib/jmock-legacy-2.5.1.jar"/>

       <classpathentryexported="true" kind="con"path="org.eclipse.jdt.junit.JUNIT_CONTAINER/4"/>

         <classpathentry kind="lib"path="lib/junit-4.9.0.jar"/>

 

具体实例如下：

finalEnrollMasService service = context1.mock(EnrollMasService.class);

                  try {

                           context1.checking(newExpectations() {

                                    {

                                              oneOf(service).validateInviteCode(with(any(Map.class)));

                                              will(returnValue(newBusinessServiceException()));

                                    }

                           });

                          

                           enrollInputAjaxAction.setEnrollMasService(service);

                           enrollInputAjaxAction.checkMgmInviteCode(request,response);

                          

                           Assert.assertEquals("-1",response.getModel().get("flag"));

                          

                  } catch (BusinessServiceExceptione) {

}

1. ANT 运行Junit 案例 实例，一开始没在Juint 标签里加上 <formattertype="plain"/> ,用例报错之后一直没有日志输出，

   加上这句话会输出TEST-xxx.HelloWorldTest.txt这个文件。

    

   建立 java工程的classpath文件

<?xml version="1.0" encoding="UTF-8"?>

<classpath>

      <classpathentry kind="src"path="src/java"/>

      <classpathentry kind="src"path="src/test"/>

      <classpathentry kind="con"path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.6"/>

      <classpathentry kind="con"path="org.eclipse.jdt.junit.JUNIT_CONTAINER/4"/>

      <classpathentry kind="output"path="bin"/>

</classpath>

 

<?xml version="1.0" encoding="GB2312"?>

  <project name="AntDemo"default="junit" basedir=".">

      <!--=================================================================== -->

             <test name="XXXX.HelloWorldTest"/>

          </junit>

      </target>

</project>

 

1. 在使用ANT执行用例的时候，报错如下Caused an ERROR

         org/hamcrest/SelfDescribing

         java.lang.NoClassDefFoundError:org/hamcrest/SelfDescribing

           后面把lib的jar 换成4.9.0问题就解决了。
