1. Installing

1. Install Junit and hamcrest

First, I download the Junit-4.12.jar and hamcrest-core-1.3.jar

Then. I add them into eclipse library

After installing,

2. Installing eclemma

Installing with Eclipse Marketplace

2. Testing

Coding

Write a java program for the triangle problem, which can calculate whether the triangle is equilateral, isosceles or scalene.

package newTest;public class Triangle {public int a;
public int b;
public int c;public Triangle(){}public Triangle(int a, int b, int c){
this.a=a;
this.b=b;
this.c=c;
}public String calculate(){if ( a + b <= c || b + c <= a || c + a <= b ){
return "Not a triangle";
}
else if( a == b && a == c ){
return "equilateral";
}
else if( a == b || a == c || b == c ){
return "isosceles";
}
else{
return "scalene";
}
}}

2. Creating Junit test case

Then, finish the test case

package newTest;import static org.junit.Assert.*;import org.junit.Before;
import org.junit.Test;public class TriangleTest {public Triangle tri;@Before
public void setUp() throws Exception {
}@Test
public void testCalculate() {
tri = new Triangle(1,1,1);
assertEquals("equilateral",tri.calculate());
tri = new Triangle(2,2,3);
assertEquals("isosceles",tri.calculate());
tri = new Triangle(2,2,1);
assertEquals("isosceles",tri.calculate());
tri = new Triangle(3,4,5);
assertEquals("scalene",tri.calculate());
tri = new Triangle(3,5,9);
assertEquals("Not a triangle",tri.calculate());
}}
