我试图按照这个非常相似的问题的答案中提供的示例进行操作，但它对我不起作用。我收到以下错误消息：

java.lang.IllegalArgumentException: Cannot subclass final class class com.myproject.test.support.ExampleEnumerable

我需要一个简单的模拟实例enum class。我不需要嘲笑它的任何方法。

这是我要模拟的课程：

public enum ExampleEnumerable implements IEnumerable<ExampleEnumerable> {
    EXAMPLE_ENUM_1("Test Enum 1"),
    EXAMPLE_ENUM_2("Test Enum 2");

    final String alias;

    ExampleEnumerable(final String alias) {
        this.alias = alias;
    }

    @SuppressWarnings({"VariableArgumentMethod", "unchecked"})
    @Override
    public @Nullable
    String getAlias(final @Nonnull IEnumerable<? extends Enum<?>>... context) {
        return alias;
    }
}

我有以下 TestNG 设置：

import static org.powermock.api.mockito.PowerMockito.mock;

@PrepareForTest({ ExampleEnumerable.class})
@Test(groups = {"LoadableBuilderTestGroup"})
public class LoadableBuilderTest {

    private ExampleEnumerable mockEnumerable;

    @BeforeMethod
    public void setUp() {
        mockEnumerable = mock(ExampleEnumerable.class);
    }
}

您需要使用 PowerMockRunner 运行它

例如。

@RunWith(PowerMockRunner.class)
@PrepareForTest({ ExampleEnumerable.class})
@Test(groups = {"LoadableBuilderTestGroup"})
public class LoadableBuilderTest {
    private ExampleEnumerable mockEnumerable;

    @BeforeMethod
    public void setUp() {
        mockEnumerable = mock(ExampleEnumerable.class);
    }
}

我通过扩展为 TestNG 处理此类事情的 PowerMockTestCase 类来完成这项工作：

@PrepareForTest(TestEnumerable.class)
@Test(groups = {"LoadableBuilderTestGroup"})
public class LoadableBuilderTest extends PowerMockTestCase {

 private TestEnumerable mockEnumerable;

 @SuppressWarnings("unchecked")
    @BeforeMethod
    public void setUp() {
        mockEnumerable = PowerMockito.mock(TestEnumerable.class);

    }
}

大家好，对我来说工作如下：

首先在 pom.xml 上添加 power mockito：

<dependency>
    <groupId>org.powermock</groupId>
    <artifactId>powermock-module-junit4</artifactId>
    <version>2.0.4</version>
    <scope>test</scope>
</dependency>

然后在我的课上：

@RunWith(PowerMockRunner.class)
@PrepareForTest({EnumClass.class})
public class EnumClassTest{
    private EnumClassTest enumClassTest;
    
    @Before
    public void setUp() {
        enumClassTest = mock(EnumClassTest.class);
    }
    
    @Test
    public void someMethod() {
        //My code test here
    }
