无法在编辑配置中 select 测试 class

Question

我创建了一个 Espresso/UIAutomator 单元测试。但是，当我尝试运行它时，Android Studio 无法识别它。 select TestLogin.java 的按钮是灰色的。我正在使用 Android Studio 2.0 预览版 5。

package com.greenrobot.yesorno.test.TestLogin

import android.support.test.rule.ActivityTestRule;
import android.support.test.runner.AndroidJUnit4;
import android.test.suitebuilder.annotation.LargeTest;

import org.junit.Rule;
import org.junit.Test;
import org.junit1.runner.RunWith;
import android.support.test.espresso.*;


/**

@RunWith(AndroidJUnit4.class)
@LargeTest
public class TestLogin extends ActivityInstrumentationTestCase2<StartActivity> {
    public TestLogin(Class<StartActivity> activityClass) {
        super(activityClass);
    }
    private UiDevice mDevice;

    @Rule
    public ActivityTestRule<Home> mActivityRule = new ActivityTestRule(Home.class);

    @Test
    public void testLogin() {
        mDevice = UiDevice.getInstance(InstrumentationRegistry.getInstrumentation());

        // Start from the home screen
        mDevice.pressHome();
        onView(withText("Hello world!")).check(matches(isDisplayed()));

        onView(withId(R.id.changeTextBt)).perform(click());

    }

Edit2：启用所有测试工件（单元测试和仪器测试）已启用。

Answer 1

再添加一个名称为 test 的软件包：com.greenrobot.yesorno.test。然后把TestLogin测试放在里面。这应该可以解决您的问题。

另外：ActivityInstrumentationTestCase2 已弃用，不能与 ActivityTestRule 一起使用。仅保留 ActivityTestRule 并删除扩展部分和构造函数。我还建议添加带有 @Before 注释的 setUp() 方法并在那里实例化 mDevice，这样它就可以用于测试 class 中的每个测试。

更新：同时删除它，同步并清理：

 androidTest {
     java.srcDirs = ['androidTest/java']
 }

Answer 2

我在 Upwork 上聘请了一名开发人员来帮我调查这个问题。主要问题是我的 androidTest src 指令缺少 'src'

    androidTest {
        java.srcDirs = ['src/androidTest/java']
    }

我的build.gradle:

    buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }

我花了 10 分钟试图让 TestLogin 格式化为代码，但它不起作用，所以我创建了一个 pastebin。 http://pastebin.com/9W3pT4rH Whosebug，你应该允许我 select 个文件，然后将它们显示为代码。
