Junit测试Service类方法教程

Junit测试是很方便的，本博客记录一下Junit测试一些Service接口的方法，这样可以不运行项目，在@Test注解的方法里直接测试

Maven引入jar包：

<properties>
        <!-- 源文件编码格式 -->
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <!-- junit版本 -->
        <junit.version>4.12</junit.version>
</properties>
<dependencies>  
        <!-- junit -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>${junit.version}</version>
            <scope>test</scope>
        </dependency>
</dependencies>

• 方法一、IOC方法
  通过ApplicationContext，ioc的方法来获取对应的bean

import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MyTest {

    private ApplicationContext applicationContext;

    @Before
    public void setUp() throws Exception {
        applicationContext = new ClassPathXmlApplicationContext(
                "classpath:spring/spring-context.xml");
    }

    @Test
    public void test1(){
        UnitService unitService = (UnitService) applicationContext
                .getBean("unitService");
        UnitModel unitdto = new UnitModel();
        unitdto.setUnitCode("15524");
        UnitModel unitvo = unitService.loadOneUnit(unitdto);
        if(unitvo != null) {
            String unitName = unitvo.getUnitName();
            System.out.println(unitName);
        }
    }
}

• 方法二：注解方式
  主要通过SpringJUnit4ClassRunner这个类，同样也要通过ContextConfiguration获取对应的spring-context配置

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;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = {"classpath:spring/spring-context.xml"})
public class MyTest {

    @Autowired
    UnitService unitService;

    @Test
    public void test1(){
        UnitModel unitdto = new UnitModel();
        unitdto.setUnitCode("15524");
        UnitModel unitvo = unitService.loadOneUnit(unitdto);
        if(unitvo != null) {
            String unitName = unitvo.getUnitName();
            System.out.println(unitName);
        }
    }
}
