在Boot环境下如何进行单元测设
例：
@SpringBootTest(classes = Springboot07JunitApplication.class)
class Springboot07TestApplicationTests {}相关属性
classes：设置SpringBoot启动类
注：如果测试类在SpringBoot启动类的包或者子包中，可以省略启动类设置，也就是省略classes的设定。
import com.ityc.service.BookService;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest
class Springboot07TestApplicationTests {
@Autowired
private BookService bookService;
@Test
public void testService() {
bookService.save();
}
}serverTimezone=UTC一定记得设置时区，否则idea会爆连接数据库错误，让人以为是密码错了！！！
spring:
datasource:
driver-class-name: com.mysql.cj.jdbc.Driver
url: jdbc:mysql://localhost:3306/ssm_db?serverTimezone=UTC
username: root
password: lyc
type: com.alibaba.druid.pool.DruidDataSource@Mapper
public interface BookDao {
@Select("select * from tbl_book where id = #{id}")
public Book getById(Integer id);
}
测试
@SpringBootTest
class Springboot08MybatisApplicationTests {
@Autowired
private BookDao bookDao;
@Test
void testGetById() {
Book book = bookDao.getById(10);
System.out.println(book);
}
}
