概述
当我们使用单元测试来验证应用程序代码时，如果代码中需要访问Redis，那么为了保证单元测试不依赖Redis，需要将整个Redis mock掉。在Spring Boot中结合mockito很容易做到这一点，如下代码：
import org.mockito.Mockito;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.connection.RedisConnection;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.*;
import org.springframework.test.context.ActiveProfiles;
import static org.mockito.Mockito.when;
/**
* mock掉整个RedisTemplate
*/
@ActiveProfiles("uttest")
@Configuration
public class RedisTemplateMocker {
@Bean
public RedisTemplate redisTemplate() {
RedisTemplate redisTemplate = Mockito.mock(RedisTemplate.class);
ValueOperations valueOperations = Mockito.mock(ValueOperations.class);
SetOperations setOperations = Mockito.mock(SetOperations.class);
HashOperations hashOperations = redisTemplate.opsForHash();
ListOperations listOperations = redisTemplate.opsForList();
ZSetOperations zSetOperations = redisTemplate.opsForZSet();
when(redisTemplate.opsForSet()).thenReturn(setOperations);
when(redisTemplate.opsForValue()).thenReturn(valueOperations);
when(redisTemplate.opsForHash()).thenReturn(hashOperations);
when(redisTemplate.opsForList()).thenReturn(listOperations);
when(redisTemplate.opsForZSet()).thenReturn(zSetOperations);
RedisOperations redisOperations = Mockito.mock(RedisOperations.class);
RedisConnection redisConnection = Mockito.mock(RedisConnection.class);
RedisConnectionFactory redisConnectionFactory = Mockito.mock(RedisConnectionFactory.class);
when(redisTemplate.getConnectionFactory()).thenReturn(redisConnectionFactory);
when(valueOperations.getOperations()).thenReturn(redisOperations);
when(redisTemplate.getConnectionFactory().getConnection()).thenReturn(redisConnection);
return redisTemplate;
}
}
上面的代码已经mock掉大部分的Redis操作了，网友想mock掉其他操作，自行加上即可。
