JUnit : Basic Installation and First Project

-> Add Library


-> First Program

STEP-1 : Create a method to get maximum value in a Class

Calculation.java

**************************************************

public class Calculation {

    public static int findMax(int arr[]){
        int max=0;
        for(int i=1;i<arr.length;i++){
            if(max<arr[i])
                max=arr[i];
        }
        return max;
    }

}

**************************************************

STEP-2 :  Create a Test class. We'll perform Test Pass and Test Fail statement.

***************************************************

import org.junit.Test;

import static org.junit.Assert.assertEquals;

public class TestClass {

    @Test
    public void testFindMax(){

        assertEquals(5, Calculation.findMax(new int[]{5, 22, 9, 7})); // Test Pass here
//        assertEquals(5, Calculation.findMax(new int[]{5, 22, 9, 7}));  // Test Fail here
       
    }
}
