一旦测试开始,我就会遇到以下异常:

    Testcase: treeCtorArgumentTest(com.xythos.client.drive.cachedtree.CachedTreeTest):  Caused an ERROR

这是我的测试:

package com.xythos.client.drive.cachedtree;

import org.junit.After;
import org.junit.AfterClass;

我有一段时间没有触及Mockito,我从未广泛使用它.但是今天在一些新代码中我想使用最佳实践,所以我使用以下Java版本提取了mockito-core 2.0.54-beta:

java version "1.8.0"
Java(TM) SE Runtime Environment (build 1.8.0-b132)
Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, mixed mode)

我需要一个用于测试的接口实例:

https://bitbucket.org/globalmentor/rincl/src/bf0e8875a1bae16247dd904e0b8bc067c9f8abc9/src/main/java/io/rincl/ResourceI18nConcern.java

public interface ResourceI18nConcern extends Concern {

    public Locale getLocale(@Nonnull Locale.Category category);

    public void setLocale(@Nonnull Locale.Category category, @Nonnull Locale locale);

    public default void setLocale(@Nonnull Locale locale) {...}

    public Resources getResources(@Nonnull final Class<?> contextClass) throws ResourceConfigurationException;

}

该接口扩展了这个(只是一个空标记接口):

https://bitbucket.org/globalmentor/csar/src/125b837e9936ddb8d6340fa99b6b5da872d1e6e5/src/main/java/io/csar/Concern.java

在我的测试中,我试图做这个简单的事情:

final ResourceI18nConcern defaultConcern=mock(ResourceI18nConcern.class);

我得到以下堆栈跟踪:

org.mockito.exceptions.base.MockitoException:
Mockito cannot mock this class: interface io.rincl.ResourceI18nConcern

Mockito can only mock visible & non-final classes. …
