ArithmeticTest.java

package com.sample.app.arithmetic;

import static org.junit.jupiter.api.Assertions.assertEquals;

import org.junit.jupiter.api.Test;

public class ArithmeticTest {

    private static int sum(int a, int b) {
        return a + b;
    }

    @Test
    public void test1() {
        assertEquals(5, sum(2, 3));
    }

}

 

DummyTest.java

package com.sample.app.dummy;

import static org.junit.jupiter.api.Assertions.assertTrue;

import org.junit.jupiter.api.Test;

public class DummyTest {

    @Test
    public void test1() {
        assertTrue(true);
    }
}

 

SelectClassesDemo1.java

package com.sample.app.suite;

import org.junit.platform.runner.JUnitPlatform;
import org.junit.platform.suite.api.SelectClasses;
import org.junit.platform.suite.api.SuiteDisplayName;
import org.junit.runner.RunWith;

import com.sample.app.arithmetic.ArithmeticTest;
import com.sample.app.dummy.DummyTest;

@RunWith(JUnitPlatform.class)
@SuiteDisplayName("JUnit Platform Suite Demo")
@SelectClasses({ DummyTest.class, ArithmeticTest.class })
