ApplicationContext.xml

 

 

?

1 2 3 4 5 6 7 8 9 10 11 12

<?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

 

 

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

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。

最后附上源码
