使用Java mockito验证scheduledExecutorService多次调用runnable

import org.mockito.Mockito;

import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.TimeUnit;

public class ExampleTest {
    public static void main(String[] args) {
        ScheduledExecutorService executorService = Mockito.mock(ScheduledExecutorService.class);
        Runnable runnable = Mockito.mock(Runnable.class);
    }
}

import org.mockito.Mockito;

import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.TimeUnit;

public class ExampleTest {
    public static void main(String[] args) {
        ScheduledExecutorService executorService = Mockito.mock(ScheduledExecutorService.class);
        Runnable runnable = Mockito.mock(Runnable.class);

        // 模拟ScheduledExecutorService每隔5秒调用一次runnable
        Mockito.when(executorService.scheduleAtFixedRate(runnable, 0, 5, TimeUnit.SECONDS))
                .thenReturn(null);

        // 执行被测试的代码，调用ScheduledExecutorService的scheduleAtFixedRate方法
        // 这里假设被测试的代码会每隔5秒调用一次runnable
        // ...

        // 验证ScheduledExecutorService在5秒后调用了3次runnable
        Mockito.verify(executorService, Mockito.times(3))
                .scheduleAtFixedRate(runnable, 0, 5, TimeUnit.SECONDS);
    }
}
