IDEA2016 maven项目配置Junit

• 添加插件：File->Settings->Plugins

• 设置生成模式：File->Settings->Other Settings

• 修改模板：File->Settings->Other Settings->Junit Generator->Junit4

#if( $entry.packageName.length()>0)package test.$entry.packageName; #end
    * @author:Hunter
    * @since:$today
    * @version 1.0 

• 在代码上右键Generate
• 结构图

src/main/java:source root

src/test/java:test root

• Main.java

/**
 * Created by Hunter on 2016/07/19.
 */
import org.apache.hadoop.conf.Configuration;

public class Main {

    public static void main(String[] args){
        for(String arg:args)
            System.out.println(arg);

    }

    public static String getColor(){
        Configuration conf =new Configuration();
        conf.addResource("Configuration-1.xml");
        return conf.get("color");
    }

    public static int getSize(){
        Configuration conf =new Configuration();
        conf.addResource("Configuration-1.xml");
        return conf.getInt("size",0);
    }
}

• 自动生成MainTest.java

import org.junit.Test;
import org.junit.Before;
import org.junit.After;

import static org.junit.Assert.assertThat;
import static org.junit.Assert.assertEquals;
import static org.hamcrest.Matchers.*;

import org.apache.log4j.Logger;

/**
* Main Tester.
*
* @author:Hunter
* @since:7/19/2016
* @version 1.0
*/
public class MainTest {
private static Logger logger=Logger.getLogger(MainTest.class);

@Before
public void before() throws Exception {
    logger.info("Test start……");
} 

@After
public void after() throws Exception {
    logger.info("Test end……");
} 

/**
*
* Method: main(String[] args)
*
*/
@Test
public void testMain() throws Exception {
    String[] args=new String[2];
    args[0]="Hello";
    args[1]="world";
    Main.main(args);
} 

/**
*
* Method: getColor()
*
*/
@Test
public void testGetColor() throws Exception {
    assertThat(Main.getColor(),is("yellow"));
}

@Test
public void testGetSize() throws Exception{
    assertEquals(Main.getSize(),10);
}

}
