如何忽略正在测试的方法中的方法调用？

Question

我正在尝试使用 mockmvc 进行测试，但失败并显示以下错误消息：

Caused by: org.apache.kafka.common.config.ConfigException

我们的服务层中有 Kafka 作为依赖项，它在我们正在测试的方法中被调用。有没有办法在测试期间忽略该特定调用？在下面的示例中，我们希望在测试期间忽略 notifyHrcOfInfectedUser()。

public UserDto changeInfectionStatus(String deviceId) {
    User user = this.userRepository.findById(deviceId)
            .orElseThrow(() -> new EntityNotFoundException("Could not find user with id " + deviceId));

    if (!hasPassedTwoWeeksMinimumRecoveryTime(user))
        throw new InfectionStatusException("Unable to change infection status since it has not been at least" +
                " two weeks since the last change.");

    UserDto updatedUser = updateStatus(user).convertToDto();
    notifyHrcOfInfectedUser(updatedUser.isInfected(), deviceId); // <-- Ignore this call during tests
    return updatedUser;
}

private void notifyHrcOfInfectedUser(boolean isInfected, String deviceId) {
    if (isInfected)
        kafkaSender.publish("infection-contact", deviceId);
}

你能模拟 kafkaSender 对象吗？然后我们可以做类似...

final KafkaSender mockKafkaSender = Mockito.mock(KafkaSender.class);
Mockito.doNothing().when(mockKafkaSender).publish(any(),any());

更新...

或者更准确地说

Mockito.doNothing().when(mockKafkaSender).publish(eq("infection-contact"),eq(expectedDeviceId));
