【JUnit】基于控制台的 Runner

环境

• JDK 6
• JUnit 4.13
• Spring Tool Suite 4.6.2
• Maven 3.6.3

main 方法运行测试

除了和 IDE 继承，右键运行之外，还可以通过 main 运行测试，并且得到运行的结果数据。
官网上将这种方式叫做基于控制台的 Runner(Console based Test runner)。

Caculator

package jiangbo.java.junit;

public class Caculator {

    public static int add(int number1, int number2) {

        return number1 + number2;
    }

    public static int subtract(int number1, int number2) {

        return number1 - number2;
    }

}

CaculatorTest

package jiangbo.java.junit;

import static org.junit.Assert.assertEquals;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.junit.runners.JUnit4;

public class CaculatorTest {

    @Test
    public void testAdd() {

        System.out.println("testAdd");
        int number = Caculator.add(1, 1);
        assertEquals(2, number);
    }

    @Test
    public void testSubtract() {

        System.out.println("testSubtract");
        int number = Caculator.subtract(1, 1);
        assertEquals(0, number);
    }
}

CaculatorMain

package jiangbo.java.junit;

import org.junit.runner.JUnitCore;
import org.junit.runner.Result;
import org.junit.runner.notification.Failure;

public class CaculatorMain {

    public static void main(String[] args) {

        Result result = JUnitCore.runClasses(CaculatorTest.class);

        for (Failure failure : result.getFailures()) {

            System.out.println(failure.getMessage());
        }

        System.out.println(result.getRunCount());
        System.out.println(result.getRunTime());
        System.out.println(result.wasSuccessful());
    }
}

运行

通过运行 main 方法，控制台输出：

testAdd
testSubtract
2
35
true
