Mockito ne peut pas se moquer de cette classe

J'essaie de me moquer d'une classe publique, mais ce faisant, Mockito lance un Mockito cannot mock this class exception.

Classe que je souhaite moquer: https://github.com/scribejava/scribejava/blob/master/scribejava-core/src/main/Java/com/github/scribejava/core/builder/ServiceBuilder.Java

Code de test:

package xyz.jacobclark.adapter;

import com.github.scribejava.apis.TwitterApi;
import com.github.scribejava.core.builder.ServiceBuilder;
import com.github.scribejava.core.model.OAuth1RequestToken;
import com.github.scribejava.core.oauth.OAuth10aService;
import org.junit.Assert;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mock;
import org.mockito.junit.MockitoJUnitRunner;

import Java.io.IOException;

import static org.hamcrest.Matchers.is;
import static org.hamcrest.core.IsInstanceOf.any;

@RunWith(MockitoJUnitRunner.class)
public class TwitterOAuthAdapterTest {
    @Mock
    ServiceBuilder serviceBuilder;

    @Test
    public void getRequestTokenShouldReturnAValidRequestToken() throws IOException {
        class TwitterOAuthAdapter {
            private final OAuth10aService service;

            public TwitterOAuthAdapter(ServiceBuilder serviceBuilder){
                this.service = serviceBuilder
                    .apiKey("")
                    .apiSecret("")
                    .build(TwitterApi.instance());
            }

            public OAuth1RequestToken getRequestToken() throws IOException {
                return this.service.getRequestToken();
            }
        }

        TwitterOAuthAdapter oAuthAdapter = new TwitterOAuthAdapter(serviceBuilder);
        Assert.assertThat(oAuthAdapter.getRequestToken(), is(any(OAuth1RequestToken.class)));
    }
}

Eu le même problème. Lorsque j'ai mis à jour ma Java version JDK vers 1.8.0_131, l'erreur a disparu.

J'ai eu le même problème. J'ai essayé tout ce qui est répertorié sur le débordement de la pile, c'est-à-dire

  • version JDK mise à jour
  • maven mis à jour
  • Fait ByteBuddy et Mockito pour utiliser des versions compatibles.
  • cache effacé
  • utiliser les dernières versions de mockito, etc.

et ceci: https://github.com/mockito/mockito/issues/1606 .

Mais rien n'a fonctionné pour moi.

J'ai effacé tout le cache, puis j'ai réinstallé Android studio qui a résolu le problème.

Il suffit probablement d'effacer tous les caches utilisés par Android Studio).

J'ai eu le même problème après avoir mis à jour vers la nouvelle version Java avec OpenJ9 JVM, maintenant j'utilise HotSpot JVM. Je n'ai plus ce problème
