mvnテストでjunitテストが見つかりません

Question

junitで単体テストの簡単なプロジェクトを作成しました。私はmvn testを実行しましたが、私は次のメッセージを受け取ります。これは私のフォルダ構造です。

[INFO]

これは私のクラスとテストクラスです。

Calculator.java

package org.sonatype.macbook; 
public class Calculator { 
     public int evaluate(String expression) { 
       int sum = 0; 
       for (String summand: expression.split("\\+")) 
         sum += Integer.valueOf(summand); 
       return sum; 
     } 
} 

CalculatorTest.java

package org.calculator.instant; 
import static org.junit.Assert.assertEquals; 
import org.junit.Test; 

public class CalculatorTest { 
     @Test 
     public void evaluatesExpression() { 
       Calculator calculator = new Calculator(); 
       int sum = calculator.evaluate("1+2+3"); 
       assertEquals(6, sum); 
     } 
} 

のpom.xml

<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

私は理由を理解することはできませんので、私は一般的にはJUnitのとJavaへの初心者ですこれらは実行されていません。

Mavenプロジェクトの構造は、 src/main/java/package/classsrc/test/java/package/testclassである必要があります。構造が正しくありません。それを更新してください。
