我尝试通过"gradlew connectedAndroidTest"运行仪器测试.我收到以下错误:

Tests on GT-I9305 - 4.3 failed: Instrumentation run failed due to 'java.lang.ClassNotFoundException'

com.android.builder.testing.ConnectedDevice > hasTests[GT-I9305 - 4.3] FAILED 
No tests found.                              
:mobile:connectedAndroidTest FAILED 

这是带有--stacktrace选项的输出:

我将以下依赖项添加到我的android项目中:

 // Unit testing dependencies
androidTestCompile 'junit:junit:4.12'
// Set this dependency if you want to use Mockito
androidTestCompile 'org.mockito:mockito-core:1.10.19'

并使用junit4 api创建一个测试(例如,Adder是一个简单的类,它总结了int):

@RunWith(MockitoJUnitRunner.class) 
public class AdderTest {

    @Test
    public void testValidAdd() {
        Adder adder = new Adder();
        assertEquals(adder.add(1,1), 2);
    }
}

当我尝试运行测试时,我得到:

运行测试测试运行已启动junit.framework.AssertionFailedError:在android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:android.test.AndroidTestRunner.runTest(AndroidTestRunner.run:)上的com.test.myapp.AdderTest中找不到测试. 176)在android.app.Instrumentation的android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:554)$ InstrumentationThread.run(Instrumentation.java:1701)完成

我在这里和这里读到,但没有任何帮助.

有谁看到我做错了/有什么输入？
