org.mockito.MockingDetails.getMockHandler()Lorg/mockito/invocation/MockHandler

Question

我想使用PowerMockito/Mockito为我的静态方法/void方法编写单元测试。但是，当我试图运行时，我得到了以下错误：

我刚开始使用powerMockito/Mockito，有人能帮我找出确切的问题吗？

--这是我想要测试的CreateTaskBuilder类方法：这里的JgitAccessor.clone()是一个静态的void，我对它使用了donothing()。

  public void Repository() throws DependencyFailureException, IOException, GitAPIException {
        try {
            ServiceAccessor.loadTmpSshTicket();
            if (!Files.exists(Paths.get(LambdaEnv.GIT_SSH_SCRIPT.getValue()))) { // getValue will throw exception on null
                throw new IllegalStateException(String.format("Environment variable GIT_SSH points to file %s but it doesn't exist.",
                        LambdaEnv.GIT_SSH_SCRIPT.getValue()));
            }
            JgitAccessor.clone(REPO_URI, CLONED_REPO_PATH);
        } catch (IOException | DependencyFailureException e) {
            log.info("Exception occurred while performing Service client integration. exception: [{}]", e.getMessage());
            e.printStackTrace();
        }
    }

，这是单元测试类:

import org.junit.Before;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.mockito.InjectMocks;
import org.mockito.Mock;

import org.mockito.Mockito;
import org.mockito.MockitoAnnotations;
import org.mockito.junit.MockitoJUnitRunner;
import org.powermock.api.mockito.PowerMockito;
import org.powermock.core.classloader.annotations.PowerMockIgnore;
import org.powermock.core.classloader.annotations.PrepareForTest;
import org.powermock.modules.junit4.PowerMockRunner;

import java.io.File;
import java.nio.file.Files;
import java.nio.file.Paths;

import static org.mockito.Mockito.*;


@RunWith(PowerMockRunner.class)
@PowerMockIgnore({"javax.management.*"})
@PrepareForTest({CreateTaskBuilder.class, LambdaEnv.class, ServiceAccessor.class, JgitAccessor.class})
public class CreateTaskBuilderTest extends TestUtils {

    @Mock
    private ServiceAccessor serviceAccessor;

    @Mock
    private JgitAccessor jgitAccessor;

    @InjectMocks
    CreateTaskBuilder builder;

    @Before
    public void setUp() {
        MockitoAnnotations.initMocks(this);
    }


    @Test
    public void loadServiceTicket_happyCase() throws Exception {
        doNothing().when(serviceAccessor).loadTmpSshTicket();
        PowerMockito.mockStatic(System.class);
        Mockito.when(System.getenv("GIT_SSH")).thenReturn("/tmp/ssh.sh");
        PowerMockito.mockStatic(Files.class);
        Mockito.when(Files.exists(Paths.get("/tmp/ssh.sh"))).thenReturn(true);
        PowerMockito.mockStatic(JgitAccessor.class);
        PowerMockito.doNothing().when(JgitAccessor.class, "clone", Mockito.anyString(), Mockito.anyString());
        builder.cloneRepository();
    }

我使用的是Mockito = 2.28.x；PowerMockMockito = 2.x；

Answer 1

看起来您的类路径上有错误的库版本。

您使用的PowerMock版本需要一个带有org.mockito.MockingDetails.getMockHandler() 在Mocktio 2.8.x中找不到。的Mockito。您可以在更高版本的在2.23.x中找到它。

查看您应该使用的是mockito版本2.23.0或更高版本。的最小版本依赖项。

因此，您需要将Mockito更新为与您的PowerMock版本2.23.x或更高版本兼容的更高版本，而不是2.8.x。
