选择create
购选所需方法就可以了
需要选择Junit
即可运行测试
绿色说明通过
需要测试的方法
package Test; public class StringUtilImpl implements StringUtil { //Rot13加密解密 @Override public String getRot13(String str) { if (str == null || str.length() == 0 || str.equals("") || str.trim().isEmpty()) { return null; } else { char[] chr = str.toCharArray(); StringBuffer buffer =new StringBuffer(); for (int i = 0; i < chr.length; i++) { if ((chr[i] >= 'A') && (chr[i] <= 'Z')) { chr[i] += 13; if (chr[i] > 'Z') { chr[i] -= 26; } } else if ((chr[i] >= 'a') && (chr[i] <= 'z')) { chr[i] += 13; if (chr[i] > 'z') { chr[i] -= 26; } }else if((chr[i] >= '0') && (chr[i] <= '9')){ chr[i] +=5; if(chr[i] > '9'){ chr[i] -= 10; } } // and return it to sender buffer.append(chr[i]); } return buffer.toString(); } } //字符串翻转 @Override public String getReverse(String str) { if (str == null || str.length()==0 || str.equals("") || str.trim().isEmpty()) { return null; } char[] arr = str.toCharArray(); String reverse = ""; for (int i = arr.length - 1; i >= 0; i--) { reverse += arr[i]; } return reverse; } //判读字符串是否为空 @Override public boolean getIsEmpty(String str) { if (str == null || str.length()==0 || "".equals(str) || str.trim().isEmpty()) { return true; } return false; } } |
测试类
package DemoJunit; import Test.StringUtilImpl; import org.junit.Assert; import org.junit.Ignore; import org.junit.Test; import Test.*; import static org.junit.Assert.*; public class StringUtilImplTest { StringUtil s = new StringUtilImpl(); @Test //@Ignore("该客户没有给钱不给他密码加密所以给他挖个坑...") public void getRot13() { Assert.assertEquals(s.getRot13("abc大Das是的3"), "nop大Qnf是的8"); Assert.assertEquals(s.getRot13("ynxsfy"), "lakfsl"); Assert.assertEquals(s.getRot13("I'm from guangdong"), "V'z sebz thnatqbat"); Assert.assertEquals(s.getRot13("StringUtil"), "FgevatHgvy"); Assert.assertEquals(s.getRot13(" "), null); Assert.assertEquals(s.getRot13(null), null); } @Test public void getReverse() { Assert.assertEquals(s.getReverse("are you ok?"), "?ko uoy era"); Assert.assertEquals(s.getReverse("I me here"), "ereh em I"); Assert.assertEquals(s.getReverse(""), null); Assert.assertEquals(s.getReverse(null), null); } @Test public void getIsEmpty() { String str = ""; Assert.assertEquals(s.getIsEmpty(null), true); Assert.assertEquals(s.getIsEmpty(" "), true); Assert.assertEquals(s.getIsEmpty(""), true); Assert.assertEquals(s.getIsEmpty(str), true); Assert.assertEquals(s.getIsEmpty("GG"), false); } } |
下面来介绍 Maven项目SSM结合Junit
这里无需添加架包在使用Maven项目字段配置好Junit
在项目的src根目录下面创建一个Test文件夹
然后点击右键选择
然后文件夹就会变绿色了
使用：
在service选择需要测试的方法然后会自动在Test文件下面生成测试类；
代码：
package com.gdnf.ssm.service; import org.apache.commons.logging.Log; import org.apache.commons.logging.LogFactory; import org.apache.log4j.spi.LoggerFactory; import org.junit.*; import org.springframework.context.support.ClassPathXmlApplicationContext; import org.apache.log4j.*; import java.util.logging.Logger; import static org.junit.Assert.*; public class BookServiceImplTest { static ClassPathXmlApplicationContext context; static Log logger ; @BeforeClass public static void init() { context = new ClassPathXmlApplicationContext("spring_root.xml"); logger = LogFactory.getLog(""); } @AfterClass public static void after() { logger.info("结束了"); } //@Ignore @Test public void getCount() { BookService bean = context.getBean(BookService.class); logger.info(bean.getCount()); logger.info(bean.getBookAll()); } } |
结果
这里配置的Log4j是输出到控制台
