导入Maven

        
            org.springframework.boot
            spring-boot-starter-test
            test

这里要单元测试的是打印出实体类的信息,而实体类的信息在.yml文件中
文件夹:
SpringBoot的单元测试_单元测试

实体类
Person.java

@Component
@ConfigurationProperties(prefix = "person")
public class Person {
    private String name;
    private Integer age;
    private Boolean boss;
    private Date date;
    private Map maps;
    private List lists;
    private Dog dog;

    @Override
    public String toString() {
        return "Person{" +
                "name='" + name + '\'' +
                ", age=" + age +
                ", boss=" + boss +
                ", date=" + date +
                ", maps=" + maps +
                ", list=" + lists +
                ", dog=" + dog +
                '}';
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public Boolean getBoss() {
        return boss;
    }

    public void setBoss(Boolean boss) {
        this.boss = boss;
    }

    public Date getDate() {
        return date;
    }

    public void setDate(Date date) {
        this.date = date;
    }


    public Map getMaps() {
        return maps;
    }

    public void setMaps(Map maps) {
        this.maps = maps;
    }

    public List getLists() {
        return lists;
    }

    public void setLists(List lists) {
        this.lists = lists;
    }

    public Dog getDog() {
        return dog;
    }

    public void setDog(Dog dog) {
        this.dog = dog;
    }
}

其中有Dog的属性
所以
Dog.java

public class Dog {
    private String name;
    private String color;



    @Override
    public String toString() {
        return "Dog{" +
                "name='" + name + '\'' +
                ", color='" + color + '\'' +
                '}';
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getColor() {
        return color;
    }

    public void setColor(String color) {
        this.color = color;
    }
}

application.yml

person:
  name: zhangsan
  age: 20
  boss: false
  date: 2020/11/22
  maps: {k1: "1",k2: "2"}
  lists:
    - lisi
    - wangwu
  dog:
    name: xiao
    color: white

最后在test下面的java包中写测试类

@RunWith(SpringRunner.class)//用Spring的驱动器跑
@SpringBootTest//SpringBoot的单元测试
public class Test01 {
    @Autowired
    Person person;
    @Test
    public void test1(){
        System.out.println(person);
    }

}

这里应用的为SpringBoot的单元测试,用的是Spring的驱动器进行测试

输出结果
SpringBoot的单元测试_单元测试_02
