Question

我想知道如何让这个测试工作！以下是测试方法：正如您所看到的，correlationId和docFamilyUUid是由UUID类随机生成的。基本上，getDocInfo首先在mockDao上调用findAllByDocId，如果返回null，则会创建一个docInfo对象以保存到数据库中。

void testGetDocInfo()
    {
        def String docId = 'I19292800fe1911e0a849005056932b99'
        def List<DocInfo> expectedResult = [expectedDocInfo]
        expect(mockDocInfoDao.findAllByDocId(docId)).andReturn(null)
        mockDocInfoDao.save(new DocInfo())
        replay(mockDocInfoDao)
        docInfoServiceImpl.getDocInfo(docId)
        verify(mockDocInfoDao)
    }

///////// DocInfoServiceClass

 public final DocInfo createDocInfo(final String docId)
    {
        final DocInfo docInfo = new DocInfo();
        docInfo.setId(docId);
        docInfo.setDocFamilyUuid(UUIDGenerator.getInstance().getUuidAsString());
        docInfo.setCorrelationId(UUIDGenerator.getInstance().getUuidAsString());
        return docInfo;
    }
    /**
     * @param docId is the document Id
     * @return the list of DocInfo objects for a particular docId
     */
    public final List<DocInfo> findAllByDocId(final String docId)
    {
        return docInfoDao.findAllByDocId(docId);
    }

    /**
     * @param docId is the document Id
     * @return the list of DocInfo objects for a particular docId
     */
    public final List<DocInfo> getDocInfo(final String docId)
    {
        List<DocInfo> docInfoList = null;
        docInfoList = docInfoDao.findAllByDocId(docId);
        if (docInfoList == null)
        {
            docInfoList = new ArrayList<DocInfo>();
            DocInfo docInfo = createDocInfo(docId);
            docInfoDao.save(docInfo);
            docInfoList.add(docInfo);
        }

        return docInfoList;
    }

您应该使用部分模拟来仅模拟createDocInfo方法。这样，您可以从那里返回任何您想要的内容，特别是具有您选择的ID的DocInfo实例。这样你就可以对getDocInfo的行为做出必要的断言（比如确保传递一个具有相同id的实例来保存和添加）。

您可以阅读部分模拟here。你没有说明你使用的是哪个版本的EasyMock，所以我认为它不是太旧了。

嘲笑一个有一些由随机值生成的字段的类？
