如何将SpringJUnit4ClassRunner的'spring 3.1'面向junit4测试转换为基于spring的junit3.8测试？

Question

此代码使用Spring 3.1和junit4以及spring-test 3.1.我想使用和加载junit3.8.x来转换此代码.这是由于遗留构建系统.我怎样才能做到这一点？弹簧的大多数在线文档都围绕下面的方法.我需要能够'加载弹簧类'.在这种情况下,我有一个XML文件,rest-servlet.xml并且'services'类被注释.我希望能够在每次测试之前加载rest-servlet spring配置文件并设置spring.

这可以通过模拟来实现SpringJUnitRunner.此类从提供的配置位置(在类路径中)加载应用程序上下文,并在测试用例中自动装配字段.

假设我们要测试一个控制器bean(在beans.xml中定义).

public class Controller {

    public String message() {
        return "Hello";
    }

}

测试用例:

public class Spring38TestCase extends TestCase {

    private Controller controller;
    private ApplicationContext context;

    @Override
    protected void setUp() throws Exception {
        //Initializing spring application context.
        context = new ClassPathXmlApplicationContext("beans.xml");
        //Setting fields in test case explicitly in case of auto wiring
        controller = context.getBean(Controller.class);
    }

    public void testController() {
        assertEquals("Hello", controller.message());
    }
}
