11-SpringBoot整合Junit
SpringBoot整合Junit
实现步骤
- 搭建SpringBoot工程
- 引入starter-test起步依赖
- 编写测试类
- 添加测试相关注解
- @RunWith(SpringRunner.class)
- @SpringBootTest(classes = 启动类.class)
- 编写测试方法
实现案例
1.搭建SpringBoot-test工程
不选择依赖,直接创建。
2. 引入starter-test起步依赖
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>
3. 编写 UserService 类,用于验证依赖注入
package com.lijw.springboottest;
import org.springframework.stereotype.Service;
@Service
public class UserService {
public String findAll(){
return "findAll";
}
}
“
注意:要将 UserService 等类写在
package com.lijw.springboottest
下,如果写到其他包,例如:com.lijw.service ,那么默认 Bean 扫描不到。”
4. 编写测试类
package com.lijw.springboottest;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
@SpringBootTest(classes = SpringbootTestApplication.class)
public class UserServiceTest {
@Autowired
UserService userService;
@Test
public void testFindAll(){
System.out.println(userService.findAll());
}
}
5. 执行测试
6.如果测试类与SpringBoot应用类在同一个package下,可以省略 (classes = SpringbootTestApplication.class)
