Android:Robolectric不支持API级别1

Question

这是我的基础测试类:

@RunWith(RobolectricTestRunner.class)
public class MainActivityTest {
  @Before
  public void setup() {
    //do whatever is necessary before every test
  }

  @Test
  public void testActivityFound() {
    Activity activity = Robolectric.buildActivity(MainActivity.class).create().get();

    Assert.assertNotNull(activity);
  }
}

当我在Android Studio下使用终端窗口执行我的测试时,出现此错误:

java.lang.UnsupportedOperationException: Robolectric does not support API level 1, sorry!

Gradle信息:

compileSdkVersion 19
buildToolsVersion "19.0.1"

    minSdkVersion 14
    targetSdkVersion 19
    versionCode 2

androidTestCompile 'org.robolectric:robolectric:2.+'
androidTestCompile 'junit:junit:4.+'

我使用上一个Android Studio版本:0.5.8

感谢你们!

有几种方法:

1. 在您AndroidManifest.xml的指定targetSdkVersion

2. 创建用于指定目标sdk 的自定义RobolectricTestRunner和覆盖getAppManifest方法.例如:

   public class MyCustomRunner extends RobolectricTestRunner {
   
       @Override
       protected AndroidManifest getAppManifest(Config config) {
   
           String manifestPath = "your_manifest_path";
           String resPath = "your_res_path";
           return new AndroidManifest(Fs.fileFromPath(manifestPath), Fs.fileFromPath(resPath)) {
               @Override
               public int getTargetSdkVersion() {
                   return 18;
               }
           }; 
       }
   }
   

   然后在你的MainActivityTest课堂上使用它@RunWith(MyCustomRunner.class).

3. @Config(emulateSdk=18)在MainActivityTest课堂上使用注释.

第三种方法是最简单的方法,但您必须注释所有测试类.我个人更喜欢第二种方法,因为它可以更灵活地配置跑步者.

根据Andrei的回答,我试图解决我的问题,但实际上我认为@Config(emulateSdk = 18)已被删除,这就解决了我的问题:

@RunWith(RobolectricGradleTestRunner.class)
@Config(constants = BuildConfig.class
     , sdk = 21)
   public class SplashActivityTest {
  ......
  }
