Spring Boot 使用 COLA分模块框架整合单元测试Junit流程

1.所需依赖（根目录下pom.xml）

<dependency>
	<groupId>org.mybatis.spring.boot</groupId>
	<artifactId>mybatis-spring-boot-starter</artifactId>
	<version>${mybatis-starter.version}</version>
</dependency>
<dependency>
	<groupId>junit</groupId>
	<artifactId>junit</artifactId>
	<version>4.13.1</version>
	<scope>test</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-test-autoconfigure -->
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-test-autoconfigure</artifactId>
	<version>${spring-boot.version}</version>
</dependency>
<dependency>
	<groupId>org.mybatis.spring.boot</groupId>
	<artifactId>mybatis-spring-boot-starter-test</artifactId>
	<version>${mybatis-starter.version}</version>
</dependency>
<dependency>
	<groupId>org.mybatis.spring.boot</groupId>
	<artifactId>mybatis-spring-boot-test-autoconfigure</artifactId>
	<version>${mybatis-starter.version}</version>
</dependency>

2.所需依赖（infrastructure 即需要访问数据库的模块）

<!--单元测试使用-->
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-test</artifactId>
</dependency>
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-test-autoconfigure</artifactId>
</dependency>
<dependency>
	<groupId>org.mybatis.spring.boot</groupId>
	<artifactId>mybatis-spring-boot-starter-test</artifactId>
</dependency>
<dependency>
	<groupId>org.mybatis.spring.boot</groupId>
	<artifactId>mybatis-spring-boot-test-autoconfigure</artifactId>
</dependency>

2.单元测试文件目录结构 infrastructure模块下

test
	java
		com.package.test
			ApplicationTest.java
			BaseTest.java
			mapper
				xxxMapperTest.java
	resources
		application.properties

application.properties 文件内含有数据库配置信息

ApplicationTest.java代码为启动代码

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.mybatis.spring.annotation.MapperScan;
//import tk.mybatis.spring.annotation.MapperScan;

@SpringBootApplication
//如果使用了 tk.mybatis 则import tk.mybatis的包
@MapperScan("com.package.*.mapper")
@ComponentScan(basePackages={"com.package"})
public class ApplicationTest {
    public static void main(String[] args) {
        SpringApplication.run(ApplicationTest.class, args);
    }
}

BaseTest.java 为我们写单元测试都需要用到的，只需要子类继承它就不需要每次都写注解了

import org.junit.Test;
import org.junit.runner.RunWith;
import org.mybatis.spring.boot.test.autoconfigure.MybatisTest;
import org.springframework.boot.test.autoconfigure.jdbc.AutoConfigureTestDatabase;
import org.springframework.test.context.junit4.SpringRunner;

//@ActiveProfiles("test")
@RunWith(SpringRunner.class)
@MybatisTest
@AutoConfigureTestDatabase(replace = AutoConfigureTestDatabase.Replace.NONE)
public class BaseTest {
    @Test
    public void test() {
    }
}

XxxMapperTest.java 的写法

public class XxxMaperTest extends BaseTest {
    @Autowired
    private XxxMapper xxxMapper;

    @Test
    public void getIpAddress() {
        XxxDO xxxDO = xxxMapper.getIpAddress(66777215L);
        System.out.println(xxxDO);
        Assert.assertNotNull(xxxDO);
    }
}

我们现在可以直接单测某个mapper的某个方法了。
