Maven学习三:使用junit测试maven project

      每个开发人员都会对自己的代码进行自定义的测试,可以是把项目run起来,手动点点页面按钮,看看操作场景和步骤点是否符合业务需要,是否存在UE上的问题。也有自己写几个测试类,把service类的输入输出是否符合标准都测试一番,这两大类,其实就是包括了前后端的测试工作,分工各有不同。在maven中集成了junit测试包,应该说maven可以集成任何你想的到或者想不到工具插件。

     在maven project-01项目中引入junit插件并不困难,只需要在pom.xml中配置好依赖包即可(IDE环境下,依赖项会自动生成)。剩下的测试代码的编写并没有任何不同。另外,test类文件需要按照/src/main/java/的文件结构(main改为test)。

    test文件夹结构如下图:


     还需要修改pom.xml文件,增加dependencies项,改后的pom.xml内容如下:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
   <modelVersion>4.0.0</modelVersion>

   <groupId>jizg.study.maven.hello</groupId>
   <artifactId>hello-first</artifactId>
   <version>0.0.1-SNAPSHOT</version>
   
   <dependencies>
          <dependency>
               <groupId>junit</groupId>
               <artifactId>junit</artifactId>
               <version>4.10</version>
               <scope>test</scope>
          </dependency>
   </dependencies>
</project>


   接下来在/src/test/java/jizg/study/maven/hello 文件夹下创建TestHello.java文件,这里需要注意,test的包结构可以自定义,要注意必备的路径为/src/test/java/,TestHello.java内容如下:
package jizg.study.maven.hello;

import org.junit.*;
import static junit.framework.Assert.*;
import jizg.study.maven.hello.*;

public class TestHello{

     @Test
     public void testHello(){     
          Hello h = new Hello();
          assertEquals(h.sayHello("jizg"),"hello :jizg");
     }
     
}


   最后,改好pom.xml和test类文件之后,可以输入mvn test命令,这会重新把项目build出来,并且输出TestHello.java中的test信息。

控制台输出如下:

     细心的朋友还会发现,在project-01目录下,新生成了一个target(项目输出)文件夹,下面包括surefire-reports(测试结果)和编译过后的class文件。mvn test可以很好的支持单元测试,maven下的好多命令可以完成其中奇葩怪异的任务,并且mvn 命令支持串行执行。比如,mvn  install、mvn clean build等等。
