powermockito：如何在枚举中模拟抽象方法

1. 枚举中的每个常量都是一个静态的最终嵌套类。因此，要模拟它，您必须在PrepareForTest中指向嵌套类。

2. MyEnum.values()

   返回预初始化的数组，因此在您的情况下也应进行模拟。
3. 每个枚举常量都只是一个

   public final static

   字段。

全部一起：

@RunWith(PowerMockRunner.class)@PrepareForTest(value = MyEnum.class,fullyQualifiedNames = {    "com.stackoverflow.q45414070.MyEnum$1",    "com.stackoverflow.q45414070.MyEnum$2"})public class MyTestClass {  @Test  public void should_return_sum_of_stubs() throws Exception {    final MyEnum one = mock(MyEnum.ONE.getClass());    final MyEnum two = mock(MyEnum.TWO.getClass());    mockStatic(MyEnum.class);    when(MyEnum.values()).thenReturn(new MyEnum[]{one, two});    when(one.myMethod()).thenReturn(10);    when(two.myMethod()).thenReturn(20);    assertThat(new Consumer().consumer())        .isEqualTo(30);  }  @Test  public void should_return_stubs() {    final MyEnum one = mock(MyEnum.ONE.getClass());    when(one.myMethod()).thenReturn(10);    Whitebox.setInternalState(MyEnum.class, "ONE", one);    assertThat(MyEnum.ONE.myMethod()).isEqualTo(10);  }}
