为什么mvn test运行测试不显示测试统计信息和测试结果

Question

如题，为什么我用mvn test运行测试时不显示别人运行时显示的测试统计信息（一共多少个测试，测试通过了几个等等）。就是下面这样的统计信息：

-------------------------------------------------------  
T E S T S  
-------------------------------------------------------  
Running test.TestHello.TestHello  
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.151 sec  
  
Results :  
  
Tests run: 1, Failures: 0, Errors: 0, Skipped: 0  

我的具体代码如下：

如下，我有一个类和一个测试类。

package com.jiaotong114;

public class Calculator {
    public int divide(int a, int b) throws Exception {
        if(0 == b) {
            throw new Exception("除数不能为0");
        }
        return a / b;
    }
}

package java.com.jiaotong114;

import org.junit.Assert;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import com.jiaotong114.Calculator;

public class CalculatorTest3 {

    private Calculator calculator = null;
    @Before
    public void setUp() throws Exception
    {
        System.out.println("set up");
        // 生成成员变量的实例
        calculator = new Calculator();
        System.out.println(calculator);
    }
    @After
    public void tearDown() throws Exception
    {
        System.out.println("tear down");
    }

    @Test
    public void TestDivide()
    {
        int result = 0;
        try
        {
            result = calculator.divide(12, 3);
        }
        catch (Exception e)
        {
            e.printStackTrace();

            // 如果抛出异常，证明测试失败,没有通过，没通过的测试计数在Failures中
            Assert.fail();
            // 如果不加这一行，如果程序进入到catch，无法判断其失败
        }
        // 判断方法的返回结果
        Assert.assertEquals(4, result);// 第一个参数是期望值，第二个参数是要验证的值

    }
    @Test
    public void TestDivideByZero()
    {
        Throwable tx = null;
        Assert.fail("没有抛出异常，测试失败");
        int result = 0;
        try
        {
            result = calculator.divide(12, 0);

            Assert.fail("没有抛出异常，测试失败");// 如果执行到这行代码，则证明没有抛出异常，说明我们的验证失败
        }
        catch (Exception e)
        {
            e.printStackTrace();
            tx = e;

        }

        Assert.assertEquals(Exception.class, tx.getClass());// 抛出的异常类型是否和期望一致
        Assert.assertEquals("除数不能为0", tx.getMessage());// 抛出的异常信息是否和期望一致

        //如果上面两个都通过，则测试通过

    }

}

我的pom文件：

运行mvn test时控制台输出：

项目结构

Answer 1

        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <version>2.10</version>
            <configuration>
                <includes>
                    <include>XXXTests.java</include>
                </includes>
            </configuration>
        </plugin>

是不是需要加上这个。

Answer 2

mvn test 使用的是surefire插件
它按照指定格式的类名来查找匹配的测试类
默认包含的测试类：
*/Test.java
*/Test.java
*/TestCase.java
默认排除的测试类：
*/AbstractTest.java
*/AbstractTestCase.java

Answer 3

对的，我是这么解决的
