Question

我无法从终端运行我的@SmallTests。我已经创建了我的设置示例，我希望您指出我做错了什么。

我正在使用我自己的默认Runner类，如下所示：

public class MyAppTestRunner extends AndroidJUnitRunner {

    @Override
    public Application newApplication(ClassLoader cl, String className, Context context) 
            throws InstantiationException, IllegalAccessException, ClassNotFoundException {
        return super.newApplication(cl, MyAppTestApplication.class.getName(), context);
    }
}

我已经在我的gradle中设置了这个跑步者：

android {
    defaultConfig {
        testInstrumentationRunner "com.MyApp.instrumentation.config.MyAppTestRunner"
    }
    testBuildType 'integrationTest'
}

我也在使用这些依赖项：

androidTestCompile com.android.support.test:runner:0.5
androidTestCompile com.android.support.test:rules:0.5

然后我创建了一个简单的类，其中一个测试用@SmallTest注释：

import android.content.Intent;
import android.support.test.filters.SmallTest;
import android.support.test.rule.ActivityTestRule;
import android.support.test.runner.AndroidJUnit4;

import com.MyApp.a.ui.activity.WelcomeActivity;

import org.junit.Before;
import org.junit.Rule;
import org.junit.runner.RunWith;


@RunWith(AndroidJUnit4.class)
public class ExampleTestPackage {

    @Rule
    public ActivityTestRule<WelcomeActivity> activityRule = new ActivityTestRule<>(
        WelcomeActivity.class, true, false
    );

    @Before
    public void before() {
        activityRule.launchActivity(new Intent());
    }

    @SmallTest
    public void exampleTest() {
        // some test code
    }
}

所以这是我的设置。根据我使用的documentation of AndroidJUnitRunner，使用小注释运行我的测试我应该做这样的事情：

运行特定的测试大小，即使用SmallTest或 MediumTest或LargeTest：adb shell am instrument -w -e size [小|介质|大] com.android.foo/android.support.test.runner.AndroidJUnitRunner

所以我在终端做的是：

adb shell am instrument -w -e size small com.MyApp.debug1.test/com.MyApp.instrumentation.config.MyAppTestRunner

但是找不到我的@SmallTest，输出是：

时间：0.001

确定（0测试）

此外，如果我从Android Studio启动测试类，那么我可以看到此错误：

如果我将@SmallTest更改为@Test（import org.junit.Test;）

我在那里使用错误的课吗？

来自@SmallTest的注释@MediumTest，android.support.test.filters等不会替换@Test注释。需要@Test注释来通知JUnit相应的方法是测试用例（http://junit.org/junit4/javadoc/latest/org/junit/Test.html）。

在您的情况下，这将有效：

@SmallTest
@Test
public void exampleTest() {
    // some test code
}

如何从终端运行仪器@SmallTests？
