Mockito and PowerMockito Error

Question

以下代码适用于PowerMockito 1.7.3版和Mockito 2.9.0版

import static org.junit.Assert.assertNotNull;
import static org.junit.Assert.assertTrue;
import java.nio.file.Files;
import java.nio.file.Path;
import java.nio.file.Paths;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.Mockito;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;
@RunWith(PowerMockRunner.class)
@PrepareForTest({FileUtils.class, Paths.class, Files.class})
public class FileUtilsTest {
@Test
public void testGetFileContents_Success() throws Exception {
String filePath = "c:\temp\file.txt";
Path mockPath = PowerMockito.mock(Path.class);
PowerMockito.mockStatic(Paths.class);
PowerMockito.mockStatic(Files.class);
Mockito.when(Paths.get(Mockito.anyString())).thenReturn(mockPath);
Mockito.when(Files.readAllBytes(Mockito.isA(Path.class))).thenReturn("hello".getBytes());
String fileContents = FileUtils.getFileContents(filePath);
assertNotNull(fileContents);
assertTrue(fileContents.length() > 0);
PowerMockito.verifyStatic(Paths.class);
Paths.get(Mockito.anyString());
PowerMockito.verifyStatic(Files.class);
Files.readAllBytes(Mockito.isA(Path.class));
}
}

然而，当我转到以下版本时-PowerMockito 2.0.0-beta.5版和Mockito 2.12.0版-我会收到以下错误

org.mockito.exceptions.base.MockitoException: 
Cannot mock/spy class java.nio.file.Paths
Mockito cannot mock/spy because :
- final class

有什么想法可能导致这个问题，或者我需要改变什么吗？

谢谢Damien

我认为您将不得不降级/推迟升级到PowerMock v2.x。

请参阅PowerMockito自v2.0.55-beta版本以来不兼容的Mockito2。

以下两个问题涵盖了PowerMock v2.x/Mockito v2.x的所有集成工作：

• PowerMock：https://github.com/powermock/powermock/issues/726
• Mockito：https://github.com/mockito/mockito/issues/1110

看起来的目标是在PowerMock v2.0.0(和一些Mockito 2.x版本)中实现这一功能，但没有明确说明何时可用。
