Redis的单元测试 - Redis mock

设计到Redis的单元测试是比较麻烦的，一般使用embeded-redis或redis-mock。因为embeded-redis启动会失败，而且没有看到错误日志（只有Can't start redis server. Check logs for details），所以最后选择了redis-mock。

添加依赖pom.xml

添加依赖项：redis-mock

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-redis</artifactId>
    </dependency>
    <dependency>
        <groupId>ai.grakn</groupId>
        <artifactId>redis-mock</artifactId>
        <version>0.1.6</version>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

Redis使用代码RedisTestApplication.java

@SpringBootApplication
public class RedisTestApplication {
    @Resource
    private StringRedisTemplate stringRedisTemplate;

    public static void main(String[] args) {
        SpringApplication.run(RedisTestApplication.class, args);
    }

    @Bean
    public CommandLineRunner commandLineRunner(ApplicationContext ctx) {
        return args -> {
            stringRedisTemplate.opsForValue().set("name", "tenmao");
            String name = stringRedisTemplate.opsForValue().get("name");
            System.out.println(name);
        };
    }
}

Redis测试代码

@RunWith(SpringRunner.class)
@SpringBootTest
public class RedisTestApplicationTests {
    @Resource
    private StringRedisTemplate stringRedisTemplate;

    private static RedisServer redisServer = null;
    @BeforeClass
    public static void init() {
        try {
            redisServer = RedisServer.newRedisServer();
            redisServer.start();
            //因为RedisServer启动的端口无法预知（如果写死的话就容易有端口冲突），所以需要实现动态端口配置。
            System.setProperty("spring.redis.port", Integer.toString(redisServer.getBindPort()));
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }

    @AfterClass
    public static void close() {
        if (redisServer != null) {
            redisServer.stop();
        }
    }

    @Test
    public void testRedis() {
        String name = stringRedisTemplate.opsForValue().get("name");
        Assert.assertEquals("tenmao", name);
    }
}
