org.mockito.MockingDetails.getMockHandler()Lorg/mockito/invo

Question

我想用PowerMockito/Mockito为我的静态方法/void方法编写单元测试。但是当我尝试运行时，我得到了以下错误：

/Users/<username>/Library/Java/JavaVirtualMachines/corretto-

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JgitAccessor.clone((是一个静态的void，我使用了donthing((。

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.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；

类路径上似乎有错误版本的库。

您正在使用的PowerMock版本需要一个带有org.mockito.MockingDetails.getMockHandler()的Mockito，这在Mocktio 2.8.x中是不可用的。您可以在2.23.x的更高版本中找到它。

查看powermock-api-mockito2 2.0.0版本的最低版本依赖关系，您应该使用mockito 2.23.0或更高版本。

因此，看起来您需要将Mockito更新到与PowerMock版本兼容的更高版本，2.23.x或更高版本而不是2.8.x。
