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")@Configurationpublic 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。
