未找到测试

Question

我正在编写单元测试。我正在从ActivityInstrumentationTestCase2扩展单元测试类。我正在很好地进行测试。但我不知道发生了什么事。现在，当我运行单元测试不运行，它抛出以下异常

`No tests were found` 

请帮助。

这里是我的单元测试类

public class UnitTest extends ActivityInstrumentationTestCase2<TREResults> { 
    TREResults trainingReinforcementResults; 

    public UnitTest(Class<TREResults>activityClass) { 
     super(activityClass); 
    } 

    @Override 
    protected void setUp() throws Exception { 
     super.setUp(); 
     trainingReinforcementResults= getActivity(); 
    } 
    public void testDownLoadTRESetting(){ 
    String userId = trainingReinforcementResults.getUS_USER_ID(); 
    Realm realm = 
    RealmSaveRestoreHelper.initRealm(trainingReinforcementResults); 
    TRESettingsModelTest treSettings = 
    realm.where(TRESettingsModelTest.class).contains("userId", 
    userId).findFirst();` 
    realm.beginTransaction(); 
    treSettings = realm.createObject(TRESettingsModelTest.class); 
    treSettings.userId = userId; 
    realm.commitTransaction(); 


} 
    @Override 
    protected void tearDown() throws Exception { 
     super.tearDown(); 
    }

是否使用JUnit3？为什么setup()和tearDown()方法是protected？他们不应该是public？
