Spring Boot单元测试中使用mockito框架mock掉整个RedisTemplate的示例

Spring Boot单元测试中使用mockito框架mock掉整个RedisTemplate的示例

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。
