Maven Surefire Plugin Jenkins

Introduction

When Maven runs tests in a project, it automatically generates XML based test reports in a directory called surefire-reports in the target under the project directory.

Sample Triangle Tests

package com.triangle.demo;

public class Triangle {
        
        public static final int NOTATRIANGLE = -1;
        public static final int SCALENE = 0;
        public static final int ISOSELES = 1;
        public static final int EQUILATERAL = 2;
        
        public static int check(int a, int b, int c) {

                boolean isTriangle;

                if((a < b + c) && (b < a + c) && (c < a + b))
                        isTriangle = true;
                else
                        isTriangle = false;

                int triangleType = NOTATRIANGLE;
                if(isTriangle) {
                        if((a == b) && (b == c))
                                triangleType = EQUILATERAL;
                        else if((a != b) && (a != c) && (b != c))
                                triangleType = SCALENE;
                        else
                                triangleType = ISOSELES;
                } else
                        triangleType = NOTATRIANGLE;
                
                return triangleType;
        }

}

Triangle Class Tests

package com.triangle.demo;

import static org.junit.Assert.*;
import org.junit.Test;

public class TriangleTest {
        @Test
        public void testEquilateralTriangle() {
              assertEquals(Triangle.EQUILATERAL,
                                Triangle.check(7, 7, 7));
        }
        
        @Test
        public void testIsoselesTriangle() {
              assertEquals(Triangle.ISOSELES,
                                Triangle.check(4, 4, 6));
        }
        
        @Test
        public void testScaleneTriangle() {
                assertEquals(Triangle.SCALENE,
                                Triangle.check(6, 7, 9));
        }
}

Let’s add some sample tests to a Maven project and run them using Jenkins build.

Console Output

Build the project and click on the Console output. You can see that Jenkins reports your tests.
