测试实体时greenDAO testSuiteConstructionFailed错误

Question

我尝试使用greenDAO示例应用程序在JUnit中编写测试用例，但是我得到了一个由InvocationTargetException导致的RuntimeException：

它甚至没有运行测试。

以下是解决此问题的代码：

import de.greenrobot.dao.test.*;

public class LibrarySummaryTest extends AbstractDaoTestLongPk<LibrarySummaryDao, LibrarySummary> {

    public LibrarySummaryTest() {
        super(LibrarySummaryDao.class);
    }

    @Override
    protected LibrarySummary createEntity(Long arg0) {
        // TODO Auto-generated method stub
        return null;
    }
}

我有什么遗失的吗？

我有一个Android应用，测试是在一个单独的应用程序。我在生成代码时表明了这一点：

schema.setDefaultJavaPackageTest("com.ralphpina.greenDao.test");
schema.setDefaultJavaPackageDao("com.ralphpina.greenDao.greendao");

我有正确定位应用程序的工具。我有一大堆JUnit测试用例运行得非常好。

我在两个应用程序中都包含了greenDAO.jar，并且我已经仔细检查过它是否在构建路径中。

我在eclipse环境中有笔记示例应用程序，JUnit测试在那里运行正常。所以我的项目必须有特定的东西。有什么建议吗？

更新

我能够通过将greenDAO中生成的类复制并粘贴到我的测试项目中来运行JUnit。显然，这并不理想，因为现在我必须记得更新它们。有没有理由JUnit找不到greenDAO类，但在目标Android项目中查看所有其他类没有问题？

Answer 1

事实证明，这个错误的原因是我在主要和测试Android项目中都包含了greenDAO.jar库。一旦我从project / libs文件夹中删除了jar，我就可以毫无问题地运行JUnit greenDAO测试了！
