Sping单元测试简单示例

测试代码：

 

package com.yanek.ioc;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.BlockJUnit4ClassRunner;
import com.yanek.util.UnitTestBase;
@RunWith(BlockJUnit4ClassRunner.class)
public class TestIOC extends UnitTestBase {

	public TestIOC() {
		super("classpath*:spring-ioc.xml");
	}
	
	@Test
	public void testSay1() {
		OneInterface oneInterface = super.getBean("oneInterface");
		oneInterface.say("This is a test1.");
	}
	@Test
	public void testSay2() {
		OneInterface oneInterface = super.getBean("oneInterface");
		oneInterface.say("This is a test2.");
	}

}
