I am studying Robolectric but an error occured

我正在学习Robolectric

我的项目目录是,

我的单元测试代码MainActivityTest如下,

package com.example.activity;

import android.app.Activity;

import com.example.BuildConfig;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.robolectric.Robolectric;
import org.robolectric.RobolectricGradleTestRunner;
import org.robolectric.annotation.Config;

import static org.junit.Assert.assertTrue;

@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class)
public class MainActivityTest {

  @Test
  public void titleIsCorrect() throws Exception {
    Activity activity = Robolectric.setupActivity(MainActivity.class);
    assertTrue(activity.getTitle().toString().equals("Deckard"));
  }
}

配置是,

它说了一些关于我的 java。 java 信息是,

为什么说

One of the two will be used. Which one is undefined.

整个代码在我的 github RobolectricGo.

看起来您是 Mac 用户。您是否在命令行上尝试过您的项目?

有一个很好的页面,其中包含有关如何开始使用 robolectric 的重要信息:http://robolectric.org/getting-started/,您会得到以下提示。

Note for Mac Users

If you are on a Mac, you will probably need to configure the default JUnit test runner configuration in order to work around a bug where Android Studio does not set the working directory to the module being tested. This can be accomplished by editing the run configurations, Defaults -> JUnit and changing the working directory value to $MODULE_DIR$.

也尝试添加

<uses-sdk android:targetSdkVersion="21" />

给你的AndroidManifest.xml

@RunWith(RobolectricTestRunner.class)
@Config(manifest = "src/main/AndroidManifest.xml")

你的测试类。
