    } 
}

JUnit test case

package com.ramesh.java8.datetime;

import java.time.LocalDate;
import org.junit.Test;

/**
 * JUnit test cases for Java8DateUtiliy Methods
 * @author javaguides.net

 */
public class Java8DateUtilityTest {

    @Test
    public void getPreviousDayTest() {
        System.out.println("Get Previous Day :: " + Java8DateUtility.getPreviousDay(LocalDate.now()));
    }
}
