未完成的验证，在编写JUnit测试用例

时间：2017-03-31 07:02:19

标签： java unit-testing exception junit mockito

我正面对

org.mockito.exceptions.misusing.UnfinishedVerificationException: 
Missing method call for verify(mock) here:
-> at systemservice.test1.SysParamsBuilderTest.testBuildProcessingInfoIf3(SysParamsBuilderTest.java:241)

我已经检查了所有参数以及正在传递以验证的对象，但是无法找出导致上述异常的原因

我想测试的条件，

if( request.getProcessType() == IPRequest.IPREQUEST_TYPE_DE )
{

     LookInfoIf rdr = new MCLLookInfoReader();

    String origAnatomy = accessor.getValue(AttributeRepNames.ANATOMY_INFO.getTagName());
    String origView = accessor.getValue(AttributeRepNames.VIEW_INFO.getTagName());
    String origPatSize = accessor.getValue(AttributeRepNames.PATIENT_SIZE.getTagName());
    String mclPatSize = getMclPatientSize(origPatSize);
    String boneLook = rdr.getDefaultLook(origAnatomy,origView,core.MCLConstants.IMAGETYPEBONETAG,mclPatSize);
    String tissueLook = rdr.getDefaultLook(origAnatomy,origView,core.MCLConstants.IMAGETYPESOFTTISSUETAG,mclPatSize);

    params.setProcessingLookBone(boneLook);
    params.setProcessingLookTissue(tissueLook);
        params.setAnatomy(origAnatomy);
        params.setView(origView);
        params.setPatientSize(origPatSize);

}

测试用例

@Test
    public void testBuildProcessingInfoIf3() throws Exception
    {
        IPRequest req=new IPRequest(1);//value of IPRequest.IPREQUEST_TYPE_DE

        IPSysParams iPSysParams = Mockito.mock(IPSysParams.class);
        PowerMockito.whenNew(IPSysParams.class).withNoArguments().thenReturn(iPSysParams);

        TagAccessor accessor=Mockito.mock(TagAccessor.class);

        MCLLookInfoReader rdr=Mockito.mock(MCLLookInfoReader.class);
        PowerMockito.whenNew(MCLLookInfoReader.class).withNoArguments().thenReturn(rdr);

        Mockito.when(accessor.getValue(AttributeRepNames.ANATOMY_INFO.getTagName())).thenReturn("ANATOMY_INFO");
        Mockito.when(accessor.getValue(AttributeRepNames.VIEW_INFO.getTagName())).thenReturn("VIEW_INFO");
        Mockito.when(accessor.getValue(AttributeRepNames.PATIENT_SIZE.getTagName())).thenReturn("PATIENT_SIZE");
        Mockito.when(rdr.getDefaultLook("ANATOMY_INFO","VIEW_INFO",core.MCLConstants.IMAGETYPEBONETAG,"All")).thenReturn("boneLook");
        Mockito.when(rdr.getDefaultLook("ANATOMY_INFO","VIEW_INFO",core.MCLConstants.IMAGETYPESOFTTISSUETAG,"All")).thenReturn("tissueLook");

        sysParamsBuilder.buildProcessingInfo(req, info);

        String origAnatomy=accessor.getValue(AttributeRepNames.ANATOMY_INFO.getTagName());
        assertEquals("ANATOMY_INFO",origAnatomy);

        String origView=accessor.getValue(AttributeRepNames.VIEW_INFO.getTagName());
        assertEquals("VIEW_INFO",origView);

        String origPatSize=accessor.getValue(AttributeRepNames.PATIENT_SIZE.getTagName());
        assertEquals("PATIENT_SIZE",origPatSize);

        PowerMockito.verifyPrivate(sysParamsBuilder).invoke("getMclPatientSize",origPatSize);//line 241

        String boneLook=rdr.getDefaultLook("ANATOMY_INFO","VIEW_INFO",core.MCLConstants.IMAGETYPEBONETAG,"All");
        assertEquals("boneLook",boneLook);

        String tissueLook=rdr.getDefaultLook("ANATOMY_INFO","VIEW_INFO",core.MCLConstants.IMAGETYPESOFTTISSUETAG,"All");
        assertEquals("tissueLook",tissueLook);

        Mockito.verify(iPSysParams).setProcessingLookBone(boneLook);//line 244
        Mockito.verify(iPSysParams).setProcessingLookTissue(tissueLook);

        // fill the Anatomy View accrodingly
        Mockito.verify(iPSysParams,Mockito.times(1)).setAnatomy(origAnatomy);
        Mockito.verify(iPSysParams).setView(origView);
        Mockito.verify(iPSysParams).setPatientSize(origPatSize);

    }

堆栈跟踪

org.mockito.exceptions.misusing.UnfinishedVerificationException: 
Missing method call for verify(mock) here:
-> at systemservice.test1.SysParamsBuilderTest.testBuildProcessingInfoIf3(SysParamsBuilderTest.java:241)

Example of correct verification:
    verify(mock).doSomething()

Also, this error might show up because you verify either of: final/private/equals()/hashCode() methods.
Those methods *cannot* be stubbed/verified.

我已经以相同的方式完成了其他测试用例并且它已经工作但我不知道为什么它不在这里工作，所有方法都是公开的。请帮我弄明白，提前致谢

3 个答案:

答案 0 :(得分：2)

从异常消息中出现问题：

PowerMockito.verifyPrivate(sysParamsBuilder).invoke("getMclPatientSize",origPatSize);//line 241

使用Google搜索powermockito verifyprivate not working我找到了以下页面：https://groups.google.com/forum/#!topic/powermock/CEdP24sb_HY

简而言之，如果您想使用PowerMockito监视您的对象，则不能使用

    SysParamsBuilder sysParamsBuilder = Mockito.spy(new SysParamsBuilder(...));

相反，你需要做

    SysParamsBuilder sysParamsBuilder = PowerMockito.spy(new SysParamsBuilder(...));

否则，如果您尝试使用PowerMockito验证私有方法调用，您将获得您所看到的异常。

答案 1 :(得分：1)

我不明白这里的mockito错误;但我的回答是朝不同的方向发展：不验证这样。

您在这里遵循几乎反模式：您希望对生产代码中发生的几乎每个和任何调用使用模拟/验证。这意味着生产代码中的细微变化将始终直接影响您的单元测试。即使您的方法的“合同”保持不变，当您使用这种验证方式时，您的单元测试也会快速中断。

我的建议：代替验证对象看到很多setter调用，你可以按照以下方式执行某些：

Params expectedParams = ... 
Params actualParams = underTest.whatever();
assertThat(actualParams, is(expectedParams));

如果简单的“等于”检查hamcrest is匹配器正在做什么在这里不起作用;你仍然可以创建自己的匹配器。

换句话说：在单元测试中远离“微观管理”您的生产代码。

专注于编写允许进行测试的代码，无需关注 内部完成的事情。相反，检查您的方法产生的“输出”！

示例：假设您像上面那样对某些params对象进行了所有模拟验证;但最后，你的方法返回其他一些 params对象......然后你的单元测试可能会通过;但整个方法都错了，因为它给你错误的结果。

答案 2 :(得分：0)

来自您的错误消息：

  

错误可能会显示，因为您验证了以下任何一种： final / private / equals（）/ hashCode（）方法。   这些方法无法进行存根/验证。

因此，请检查是否有任何此方法

final

是{{1}}。
