我在junit中创建了一个单元测试的简单项目。我已经运行了mvn test，但是当我这样做时，我收到了以下消息。这是我的文件夹结构。

这些是我的班级和考试班。
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);
}
}

我是junit和java的新手，所以我无法弄清楚为什么这些没有运行。
答案 0 :(得分：2)
Maven项目结构应该是：
src/main/java/package/class src/test/java/package/testclass。你的结构不正确。请更新它。
