这些是我的课程和测试课程.
And these are my class and test class.
Calculator.java
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
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);
}
}

我通常是junit和java的新手，所以我不知道为什么它们没有运行.
I am a newbie to junit and java in general so I cannot figure out why these are not running.
推荐答案
Maven项目结构应为:
src/main/java/package/class src/test/java/package/testclass.您的结构不正确.请更新.
Maven project structure should be:
src/main/java/package/class src/test/java/package/testclass. Your structure is not correct. Please update it.
