使用junit

首先导入依赖

<dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.12</version>
      <scope>test</scope>
    </dependency>

代测代码

public class Max {
    public int getA() {
        return a;
    }

    public void setA(int a) {
        this.a = a;
    }

    private int a;

    public int getB() {
        return b;
    }

    public void setB(int b) {
        this.b = b;
    }

    private int b;
    public Max(int a,int b){
        this.a=a;
        this.b=b;

    }
    public int getmax(){
        return a>b?a:b;


    }
}

bean的配置

<bean id="max" class="com.spring.IoC.work1.Max">
        <constructor-arg name="a" value="2"/>
        <constructor-arg name="b" value="5"/>

    </bean>

测试代码

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import static org.junit.Assert.*;

//指定单元测试环境
@RunWith(SpringJUnit4ClassRunner.class)
//指定配置文件路径
@ContextConfiguration(locations = {"/spring.xml"})
public class MaxTest {
    //自定注入Max
    @Autowired
    private Max max;

    @Test
    public void getMax() {
        assertEquals(5,max.getmax() );
    }
}
