我正在尝试测试一个类，并且我有自己的参数 Mathcher 来匹配这些参数。这是代码：

 @Test
public void testDoBindModelsToForm()
{
    OrganizationToRelatedSubregionsConverter organizationToRelatedSubregionsConverter = mock(OrganizationToRelatedSubregionsConverter.class);
    List<Organization> subregion1 = new ArrayList<Organization>();

    Organization subregionOrg1 = CommonentityFactory.eINSTANCE.createOrganization();
    subregionOrg1.setMID(OrganizationMID.create(DOMAIN, 100L));
    subregionOrg1.setNameFormatted("Subregion 1"); //$NON-NLS-1$
    subregion1.add(subregionOrg1);
    when(
            organizationToRelatedSubregionsConverter.convert(Matchers
                    .argThat(new OrganizationMIDMatcher(catchmentArea1.getMID())))).thenReturn(
            subregion1);

    CatchmentFormController catchmentFormController = new CatchmentFormController(
            catchmentForm, DOMAIN, conversationDescriptor, configuration, registrationManager,
            catchment, null, LaunchMode.ADD, organizationToRelatedSubregionsConverter);

    catchmentFormController.renderDynamicForm();
    organizationToRelatedSubregionsConverter.convert(catchmentArea1.getMID());
}

这是我的自定义 Matcher 类：

static class OrganizationMIDMatcher extends ArgumentMatcher<OrganizationMID>
{
    private OrganizationMID expectedOrganizationMID;

    public OrganizationMIDMatcher(OrganizationMID expectedOrganizationMID)
    {
        this.expectedOrganizationMID = expectedOrganizationMID;
    }

    @Override
    public boolean matches(Object argument)
    {
        if (argument != null && argument instanceof OrganizationMID)
        {
            OrganizationMID actualOrganization = (OrganizationMID) argument;
            return actualOrganization.equals(expectedOrganizationMID);
        }
        return false;
    }
}

当我运行测试时，我收到以下错误。我使用的 Mockito 依赖项是 Mockito-all 1.8.5。

  > java.lang.LinkageError: loader constraint violation:
 when resolving method "org.mockito.Matchers.argThat(Lorg/hamcrest/Matcher;)Ljava/lang/Object;" 
 the class loader (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader)
 of the current class, com/cerner/registration/ui/internal/converters/OrganizationToRelatedSubregionsConverterTest,
 and the class loader
    (instance of org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader) for resolved class,
 org/mockito/Matchers, have different Class objects for the type org/hamcrest/Matcher used in the signature

关于这里可能是什么问题的任何想法？

你不应该使用mockito-allwith junit 4.8.2-v370。两者都包含hamcrest依赖项，并且由于它们在 OSGi 环境中使用不同的类加载器，因此这些类将不兼容。作为一种解决方法，您应该考虑使用mockito-core（1.8.5如果想使用相同的版本）和至少4.9版本junit（它们开始hamcrest正确捆绑的地方：作为依赖项）。

或者-不要遵循-您可以“分叉”4.8.2版本junit并在没有类的情况下重新打包它hamcrest。
