mockito 声明为准备状态时出现异常

我不明白为什么会出现这种情况，因为我的测试肯定要求PowerMock为它做准备。

@PrepareForTest({AmazonSQSClientBuilder.class})
@RunWith(PowerMockRunner.class)
@PowerMockIgnore({"javax.*", "org.apache.logging.*"})
class EncodingAdapterTest {

    ...
    private AmazonSQSClientBuilder sqsBuilder;
    private AmazonSQS sqsClient;
    private AmazonSNS snsClient;
    private SendMessageResult sqsResult;
    private PublishResult snsResult;

    @BeforeEach
    void setUp() {

        sqsClient = PowerMockito.mock(AmazonSQS.class);
        PowerMockito.mockStatic(AmazonSQSClientBuilder.class);
        AmazonSQSClientBuilder mockBuilder = PowerMockito.mock(AmazonSQSClientBuilder.class);
        PowerMockito.when(AmazonSQSClientBuilder.standard()).thenReturn(mockBuilder);
        sqsBuilder = PowerMockito.mock(AmazonSQSClientBuilder.class);
    }

虽然我在一开始就有@PrepareForTest({AmazonSQSClientBuilder.class})，但它显示PowerMockito.mockStatic(AmazonSQSClientBuilder.class);行出错。
错误如下：

[Ljava.lang.Object;@259661b4
The class com.amazonaws.services.sqs.AmazonSQSClientBuilder not prepared for test.
org.powermock.api.mockito.ClassNotPreparedException:

    at org.powermock.api.mockito.PowerMockito.mockStatic(PowerMockito.java:62)
    at package.adapters.EncodingAdapterTest.setUp(EncodingAdapterTest.java:76)

我错过了什么吗？

Mockito

你可以试着扩展PowerMockTestCase。它会解决你的问题。

class EncodingAdapterTest extends PowerMockTestCase

顺便说一句，我推荐使用mockito-inline而不是Powermock来模拟静态方法或类。因为它比Powermock更容易也更流行。你可以轻松地模拟静态，而不需要多余的注解，如下所示：

try (MockedStatic<AmazonSQSClientBuilder> builder = Mockito.mockStatic(AmazonSQSClientBuilder.class)) {
        builder.when(() -> AmazonSQSClientBuilder.standard())
        .thenReturn("somthing");
}
