java.lang.NoClassDefFoundError：org / robolectric / internal / ShadowExtractor [英] java.lang.NoClassDefFoundError: org/robolectric/internal/ShadowExtractor

问题描述

使用

  testImplementation'org.robolectric：shadows-play-services：3.4-rc2'
 testImplementation org.robolectric：robolectric：3.6.1
 testImplementationcom.google.android.gms：play-services-auth：$ rootProject.ext.googlePlayServicesVersion// // robolectric影子虚假地需要这
  

我试过这个：

  import com.google.android.gms.common.ConnectionResult; 
 import com.google.android.gms.common.GoogleApiAvailability; 
 
导入org.junit.Before; 
 import org.junit.runner.RunWith; 
 import org.robolectric.RobolectricTestRunner; 
 import org.robolectric.annotation.Config; 
导入org.robolectric.shadows.gms.Shadows; 
导入org.robolectric.shadows.gms.common.ShadowGoogleApiAvailability; 
 
 @RunWith（RobolectricTestRunner.class）
 @Config（manifest = Config.NONE，shadows = {ShadowGoogleApiAvailability.class}）
公共抽象类BaseTest {
 @在
之前public void setUp（）{
 final ShadowGoogleApiAvailability shadowGoogleApiAvailability $ b = Shadows.shadowOf（GoogleApiAvailability.getInstance（））; 
 final int expectedCode = ConnectionResult.SUCCESS; 
 shadowGoogleApiAvailability.setIsGooglePlayServicesAvailable（expectedCode）; 
 
 
 $ / code> 

但是，我的测试失败并出现这个奇怪的错误：

  java.lang.NoClassDefFoundError：org / robolectric / internal / ShadowExtractor 
 at org.robolectric.shadows.gms。 Shadows.shadowOf（Shadows.java:37）
 at ...... BaseTest.setUp（BaseTest.java:19）
  

我在做什么错误，如何解决这个问题？


解决方案

Google Play服务shadow已被重命名为



  testImplementation'org.robolectric：shadows-playservices：3.6.1'
  

根据 https://github.com/robolectric/robolectric/issues/3489 ，这是Robolectric 3.5.x应该使用的。请注意，官方文档 - http://robolectric.org/using-add-on-modules / - 尚未更新以反映此更改。

Using

testImplementation 'org.robolectric:shadows-play-services:3.4-rc2'
testImplementation "org.robolectric:robolectric:3.6.1"
testImplementation "com.google.android.gms:play-services-auth:$rootProject.ext.googlePlayServicesVersion" // the robolectric shadow bogusly needs this

I am trying this:

import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.GoogleApiAvailability;

import org.junit.Before;
import org.junit.runner.RunWith;
import org.robolectric.RobolectricTestRunner;
import org.robolectric.annotation.Config;
import org.robolectric.shadows.gms.Shadows;
import org.robolectric.shadows.gms.common.ShadowGoogleApiAvailability;

@RunWith(RobolectricTestRunner.class)
@Config(manifest = Config.NONE, shadows = {ShadowGoogleApiAvailability.class})
public abstract class BaseTest {
        @Before
        public void setUp() {
                final ShadowGoogleApiAvailability shadowGoogleApiAvailability
                        = Shadows.shadowOf(GoogleApiAvailability.getInstance());
                final int expectedCode = ConnectionResult.SUCCESS;
                shadowGoogleApiAvailability.setIsGooglePlayServicesAvailable(expectedCode);
        }
}

however, my tests are failing with this weird error:

java.lang.NoClassDefFoundError: org/robolectric/internal/ShadowExtractor
    at org.robolectric.shadows.gms.Shadows.shadowOf(Shadows.java:37)
    at ......BaseTest.setUp(BaseTest.java:19)

What am I doing wrong, how to fix this?

解决方案

The Google Play Services shadow has been renamed to

testImplementation 'org.robolectric:shadows-playservices:3.6.1'

according to https://github.com/robolectric/robolectric/issues/3489 and this is what should be used with Robolectric 3.5.x. Note that the official docs - http://robolectric.org/using-add-on-modules/ - is not yet updated to reflect this change.
