<? xml version = "1.0" encoding = "UTF-8" ?> < beans xmlns = "http://www.springframework.org/schema/beans"      xmlns:xsi = "http://www.w3.org/2001/XMLSchema-instance"      xmlns:context = "http://www.springframework.org/schema/context"      xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd          http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd">      < bean id = "employee" name = "employee" class = "com.tfry.spring.Employee" autowire = "default" >          < constructor-arg name = "age" value = "20" ></ constructor-arg >          < constructor-arg name = "name" value = "zhangsan" ></ constructor-arg >      </ bean >   </ beans >

 

 

Employee.java

public class Employee {      private Integer age;      private String name;      public Integer getAge() {          return age;      }        public void setAge(Integer age) {          this .age = age;      }        public String getName() {          return name;      }        public void setName(String name) {          this .name = name;      }                    public Employee(Integer age,String name){          this .age=age;          this .name=name;      }            @Override      public String toString(){          return "Employee name is " +name+ ",age is" +age;                }   }

 

 

三、主要步骤

 

1.使用springframework提供的单元测试

包的路径:org.springframework.test.context.junit4下

只需要加入两个注解就可以实现单元测试的功能

 

?

1 2	@RunWith (SpringJUnit4ClassRunner. class ) @ContextConfiguration (locations={ "classpath*:ApplicationContext.xml" })

 

 

@RunWith 大家并不陌生,junit4里用它来做junit加载器

 

@ContextConfiguration 主要用来加载spring的配置文件路径:是一个字符串数组,可以加载多个spring配置文件

2.基本使用

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

import static org.junit.Assert.assertEquals;   import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.ApplicationContext; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;   @RunWith (SpringJUnit4ClassRunner. class ) @ContextConfiguration (locations = { "classpath:ApplicationContext.xml" }) public class EmpolyeeTest {      @Autowired      ApplicationContext ctx;            @Test      public void testEmployee(){          Employee employee =(Employee) ctx.getBean( "employee" );          assertEquals( "zhangsan" ,employee.getName());      }   }

 

 

3.封装基于AbstractJUnit4SpringContextTests的测试基类

SpringTest.java

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22

import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.context.ApplicationContext; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;   @RunWith (SpringJUnit4ClassRunner. class ) @ContextConfiguration (locations={ "classpath*:ApplicationContext.xml" }) public class SpringTest extends AbstractJUnit4SpringContextTests {                 public <T> T getBean(Class<T> type){      return applicationContext.getBean(type);     }          public Object getBean(String beanName){      return applicationContext.getBean(beanName);     }     protected ApplicationContext getContext(){      return applicationContext;     }

 

 

然后其他测试类只需要继承该类即可,可以省去每次都要绑定Application对象。

下一步就是在webapp中如何进行单元测试和如何结合hibernate等ORMapping框架进行单元测试。
