SpringBoot单元测试

SpringBoot单元测试

1. 创建SpringBoot容器

新建一个maven项目，spring-boot-test

配置pom.xml parent属性

<parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.5.15</version>
</parent>

2. 配置依赖项(spring-boot-starter-test和junit测试功能包)

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <scope>test</scope>
</dependency>

3. 配置web包

<dependency>
      <groupId>org.springframework.boot</groupId>
      <artifactId>spring-boot-starter-web</artifactId>
</dependency>

完成pom如下

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>


    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.5.15</version>
    </parent>
    <groupId>cn.axj</groupId>
    <artifactId>spring-boot-test</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>


    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>
</project>

4. 在java目录下创建包cn.axj.test,并创建TestApplication入口类

package cn.axj.test;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class TestApplication {

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

至此springboot容器创建完成

5. 新建model包，并创建User类。新建service包，并创建UserService类

   User类代码：

package cn.axj.test.model;


public class User {

    private Integer id;

    private String name;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

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

​ UserService类代码

package cn.axj.test.service;

import cn.axj.test.model.User;
import org.springframework.stereotype.Service;

@Service
public class UserService {

    //模拟通过id获取User对象
    public User getUser(Integer id){
        User user = new User();
        user.setId(id);
        user.setName("张三");
        return user;
    }
}

6. test目录下新建UserServiceTest类

package cn.axj.test.user;

import cn.axj.test.model.User;
import cn.axj.test.service.UserService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.test.context.junit4.SpringRunner;

import javax.annotation.Resource;

@SpringBootTest
@RunWith(SpringRunner.class)
public class UserServiceTest {
    @Resource
    private UserService userService;
    
    @Test
    public void test(){
        User user = userService.getUser(1);
        assert user != null;
        assert user.getId() == 1;

    }
}
