Java EE 8 Development with Eclipse - Third Edition

By: Ram Kulkarni

Overview of this book

Java EE is one of the most popular tools for enterprise application design and development. With recent changes to Java EE 8 specifications, Java EE application development has become a lot simpler with the new specifications, some of which compete with the existing specifications. This guide provides a complete overview of developing highly performant, robust and secure enterprise applications with Java EE with Eclipse. The book begins by exploring different Java EE technologies and how to use them (JSP, JSF, JPA, JDBC, EJB, and more), along with suitable technologies for different scenarios. You will learn how to set up the development environment for Java EE applications and understand Java EE specifications in detail, with an emphasis on examples. The book takes you through deployment of an application in Tomcat, GlassFish Servers, and also in the cloud. It goes beyond the basics and covers topics like debugging, testing, deployment, and securing your Java EE applications. You'll also get to know techniques to develop cloud-ready microservices in Java EE.

Creating and executing unit tests using Eclipse JEE


To understand how to write unit tests, let's take the JDBC version of the Course Management application that we developed in Chapter 4, Creating JEE Database Applications. Let's start with a simple test case for validating a course. The following is the source code of Course.java:

package packt.book.jee.eclipse.ch5.bean; 
 
import java.sql.SQLException; 
import java.util.List; 
 
import packt.book.jee.eclipse.ch5.dao.CourseDAO; 
 
public class Course { 
  private int id; 
  private String name; 
  private int credits; 
  private Teacher teacher; 
  private int teacherId; 
  private CourseDAO courseDAO = new CourseDAO(); 
 
  public int getId() { 
    return id; 
  } 
  public void setId(int id) { 
    this.id = id; 
  } 
  public String getName() { 
    return name; 
  } 
  public void setName(String name) { 
    this.name = name; 
  } 
  public int getCredits() { 
    return credits; 
  } 
  public void setCredits(int credits) {
