07 Spring中使用Junit

在pom.xml添加test依赖

<dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.12</version>
      <scope>test</scope>
    </dependency>
      <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>${spring.version}</version>
      </dependency>
    <!--spring-text依赖-->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-test</artifactId>
      <version>${spring.version}</version>
    </dependency>

以Max类比较大小为例

Max类

package com.spring.IoC;

/**
 * Created by User on 2019/3/4.
 * 待测程序，求两个数的较大值
 */
public class Max {
    private int a;
    private int b;

    public Max(int a, int b) {
        this.a = a;
        this.b = b;
    }
    public int getMax(){
        return a > b ? a : b;
    }
}

bean

<!--配置一个Max的bean-->
    <bean id="max" class="com.spring.IoC.Max">
        <constructor-arg name="a" value="5"/>
        <constructor-arg name="b" value="3"/>
    </bean>

将光标放在public class Max一行 快捷键“alt+enter” 选择 Creat Test

选择如图：

自动生成MaxTest

package com.spring.IoC;

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.*;

/**
 * Created by User on 2019/3/4.
 */
//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 {
//    自动注入max（仓库管理给斧头）
    @Autowired
    private Max max;

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

}
