Question

以下代码适用于PowerMockito版本1.7.3和Mockito版本2.9.0

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));
    }

}

但是 - 当我转到以下版本 - PowerMockito版本2.0.0-beta.5和Mockito版本2.12.0时 - 我收到以下错误

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

任何想法可能导致此问题或我需要更改的内容？

谢谢达明

我认为你必须降级/推迟升级到PowerMock v2.x.

请参阅PowerMockito not compatible Mockito2 since their v2.0.55-beta release。

所有PowerMock v2.x / Mockito v2.x集成工作都包含在以下两个问题中：

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

看起来像，目标是让它在PowerMock v2.0.0（以及一些Mockito 2.x版本）中运行，但是没有明确说明何时可用。
