Trying to mock IntConsumer with Mockito fails
问题
我正在尝试模拟 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));
}
}
但在 'verify' 部分失败，出现以下错误代码：
Method threw 'org.mockito.exceptions.base.MockitoException' exception. Cannot evaluate $java.util.function.IntConsumer$$EnhancerByMockitoWithCGLIB$$3ee084c4.toString()

and it fails on the 'verify' with below error code:

你需要告诉Mockito应该在IntConsumer模拟上验证哪个方法。你的验证代码应该类似于：
verify(intConsumerMock, times(ticksToRun)).accept(anyInt());
例如，可以参考Baeldung上的教程。
英文:
You need to tell Mockito what method it is supposed to verify on the IntConsumer mock. Your verification code should look something like:
verify(intConsumerMock, times(ticksToRun)).accept(anyInt());
See for example the tutorial at Baeldung.
