我试着按照这个非常相似的问题的答案提供的例子,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

我需要一个枚举类的简单模拟实例.我不需要模拟它的任何方法.

这是我想要模拟的类：

public enum ExampleEnumerable implements IEnumerable {

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);

}

}
