Question

我使用Robolectric工具为我的应用程序创建了一个简单的junit测试。

import org.junit.Before;
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.assertNotNull;

@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class,sdk = 21)
public class MainActivityTest {
    MainActivity activity;
    @Before
    public void setUp(){
      activity= Robolectric.setupActivity(MainActivity.class);
     }

    @Test
    public void shouldNotBeNull(){
     assertNotNull(activity);
    }
 }

基本上这个测试应该通过，因为活动不是null。但是我得到了这个奇怪的例外。

任何想法发生了什么？

这是Robolectric 3.0中的一个已知错误（请参阅此处的问题https://github.com/robolectric/robolectric/issues/1810），已在版本3.1中修复，方法是将setConvexPath()添加到Outline类的阴影中。

Robolectric给出了一个例外
