java - 尝试用 Mockito 模拟 IntConsumer 失败

Question

我正在尝试 mock IntConsumer:

class TickerServiceImplTest {
@Test
void testRunIterations() {
    TickerServiceImpl tickerService = new TickerServiceImpl();
    int ticksToRun = 100;
    tickerService.setTicksToRun(ticksToRun);
    IntConsumer intConsumerMock = mock(IntConsumer.class);
    tickerService.run(intConsumerMock);
    verify(intConsumerMock, times(ticksToRun));
}

“验证”失败，错误代码如下:

方法抛出“org.mockito.exceptions.base.MockitoException”异常。
无法评估 $java.util.function.IntConsumer$$EnhancerByMockitoWithCGLIB$$3ee084c4.toString()

Answer 1

您需要告诉 Mockito 它应该在 IntConsumer 模拟上验证什么方法。您的验证码应类似于:

verify(intConsumerMock, times(ticksToRun)).accept(anyInt());

例如，请参阅 Baeldung 处的教程.
