为 Maven 项目运行 JUNIT mockito 和 powermock 时出现 java.lang.VerifyError答案

【问题标题】：java.lang.VerifyError in while running a JUNIT mockito and powermock for maven project为 Maven 项目运行 JUNIT mockito 和 powermock 时出现 java.lang.VerifyError
【发布时间】：2016-02-16 22:15:13
【问题描述】：

这是我运行clean cobertura:cobertura 时的例外情况。我尝试从 Eclipse 将其作为 JUNIT 运行，但仍然没有运气。
我正在为我的项目使用以下依赖项。

org.mockito mockito-all 1.10.19
org.mockito mockito-core 1.10.19
junit junit 4.11
junit-addons junit-addons 1.4
org.powermock powermock-module-junit4 1.6.2
org.powermock powermock-api-mockito 1.6.2

更新：搜索类代码：

@Service(SearchService.class)
@Component(label = "Search Service", metatype = true, immediate = true)
public class SearchServiceImpl implements SearchService
{
    private final Logger logger = LoggerFactory.getLogger(getClass());
    @Override
    public final SearchResult getResult(final SlingHttpServletRequest slingRequest, final Map<String,
         String> predicateParameterMap, final String searchRootPath, final int startPage, final int resultsPerPage)

        // Populate search result
        final SearchResult searchResult = new SearchResult();
        searchResult.setCurrentPage(calculateCurrentPage(result.getStartIndex(), result.getHitsPerPage()));

    }

    private int calculateTotalPages(final long totalMatches, final long hitsPerPage)
    {

        {
            return 0;
        }

        Query query = null;
        query = queryBuilder.createQuery(PredicateGroup.create(predicateParamMap), session);
        return query;
    }

}

上述源类的测试类：

public class SearchServiceImplTest
{

    private SearchServiceImpl searchService;
    private SearchResult result;
    private HashMap<String, String> predicateParameterMap;
    private ResourceResolver resourceResolver;
    private QueryBuilder queryBuilder;
    private Session session;
    private Query query;
    private PredicateGroup predicateGroup;
    private java.util.List<Hit> hits;
    private SlingHttpServletRequest request = null;
    private com.project.digital.models.SearchResult searchResult;
    private static long TEST_START_INDEX = 0;
    private static long TEST_HITS_PER_PAGE = 2;
    private static long TEST_TOTAL_MATCHES = 5;

    private static String TEST_SEARCH_ROOT_PATH = "/content/testSite/en";

    @SuppressWarnings("unchecked")
    @Before
    public void setUp() throws Exception
    {
        searchService= spy(new SearchServiceImpl());
        predicateParameterMap = mock(HashMap.class);
        result = mock(SearchResult.class);
        request = mock(SlingHttpServletRequest.class);
        resourceResolver = mock(ResourceResolver.class);
        queryBuilder = mock(QueryBuilder.class);
        session = mock(Session.class);
        query = mock(Query.class);
        predicateGroup = mock(PredicateGroup.class);
        hits = (java.util.List<Hit>) mock(List.class);

        searchResult = new com.project.digital.models.SearchResult();

        Mockito.when(new com.project.digital.models.SearchResult()).thenReturn(searchResult);
        when(request.getResourceResolver()).thenReturn(resourceResolver);
        when(resourceResolver.adaptTo(QueryBuilder.class)).thenReturn(queryBuilder);
        when(resourceResolver.adaptTo(Session.class)).thenReturn(session);
        when(PredicateGroup.create(predicateParameterMap)).thenReturn(predicateGroup);
        when(queryBuilder.createQuery(predicateGroup, session)).thenReturn(query);
        when(query.getResult()).thenReturn(result);
    }


    private void mockSearchResult(long startIndex, long hitsPerPage, long totalMatches, List<Hit> hits)
    {
        when(result.getStartIndex()).thenReturn(startIndex);
        when(result.getHitsPerPage()).thenReturn(hitsPerPage);
        when(result.getTotalMatches()).thenReturn(totalMatches);
        when(result.getHits()).thenReturn(hits);

    }
}

当我在我的测试类中使用 PredicateGroup 时，我得到了这个异常。

【问题讨论】：

我已将 powermockito 更改为 mockito。现在我收到以下错误：java.lang.VerifyError: (class: com/day/cq/search/Predicate, method: <init> signature: (Ljava/lang/String;Ljava/lang/String;)V) Constructor must call super() or this() at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Unknown Source) at java.lang.Class.getDeclaredConstructors(Unknown Source) at org.powermock.api.mockito.repackaged.ClassImposterizer.setConstructorsAccessible(ClassImposterizer.java:85)...
尝试使用 Java 8、JUNIT 4.12 和 Mockito 1.10.8 但无法解决问题。
感觉像是特定于您的代码或您对 com.day.cq.search.Predicate 的使用的错误。您能否尝试尽可能简化您的测试/CUT 并将其发布在此处？
@Eric 添加了代码。
我缩小到罪魁祸首，即 PredicateGroup PredicateGroup predicateGroup = Mockito.mock(PredicateGroup.class); 每当我使用这个类时，我都会收到上述错误。

标签： java maven mockito verifyerror powermockito

【解决方案1】：

添加 -noverify 作为 JVM 参数。

我们遇到了同样的问题，VerifyError 来自 java.lang.Class.getDeclaredConstructors0()，Powermock ClassImposterizer 类在堆栈跟踪中更远。

我们的依赖项也几乎与您的相同 - 我们使用 jUnit 4.12 而不是 4.11，但使用相同版本的 PowerMock (1.6.2) 和 Mockito (1.10.19)。

由于我们使用 Jenkins 来启动 Ant 脚本而不是 Maven，因此我将此参数添加到 junit Ant 任务中 - 您必须根据 Maven 进行适当修改：

<jvmarg line="-noverify"/>

当然，我们不希望“-noverify”应用于我们所有的测试，所以我从主套件中提取了遇到 VerifyError 异常的那个并单独运行它。您的上下文可能不同。
