当Espresso添加到项目中时，Mockito异常

Question

我在项目中成功地使用了Mockito，然后我决定添加一些Espresso测试(如下所述：https://developer.android.com/training/testing/ui-testing/espresso-testing.html#build)我被卡住了——当我在我的build.gradle中添加意式浓缩咖啡时，我会遇到Mockito的问题。

当Mockito正常工作时，我在build.gradle中的依赖项，例如，我使用Mockito的测试通过：

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:23.4.0'
    testCompile 'junit:junit:4.12'
    //Mockito framework
    testCompile 'org.mockito:mockito-core:1.10.19'
    // https://mvnrepository.com/artifact/org.powermock/powermock-module-junit4
    testCompile group: 'org.powermock', name: 'powermock-module-junit4', version: '1.6.4'
    testCompile 'org.powermock:powermock-api-mockito:1.5.5'
    androidTestCompile ('com.android.support:support-annotations:23.4.0')
    //androidTestCompile ('com.android.support.test.espresso:espresso-core:2.2.2')
}

当我取消注释最后一行以包含com.android.support.test.sespresso:sespresso-core:2.2.2时，我再次运行测试，其中一些测试出现以下错误：

java.lang.IllegalAccessError: class org.mockito.internal.creation.jmock.ClassImposterizer$1 cannot access its superclass org.mockito.internal.creation.cglib.MockitoNamingPolicy

    at org.mockito.Mockito.spy(Mockito.java:1368)
    at todolistj.todolist.unittest.CustomClass.size(CustomClass.java:54)

所有失败的测试都在Mockito.spy或Mockito.mock方法上失败。类似于：

CustomClass1 li1 = Mockito.spy(new CustomClass1(somevar));

或

View vm= Mockito.mock(View.class);

任何帮助都将不胜感激！

Answer 1

这不是Mockito的问题，而是Powermock的问题，它依赖于旧版本的Mockito。

更新此库依赖项或从Powermock渐变依赖项中排除mockito。
