Course Overview

Mastering Test Driven Development using JUnit is a five-day, comprehensive hands-on test-driven development / JUnit / TDD training course geared for developers who need to get up and running with essential Test-driven development programming skills using JUnit and various open-source testing frameworks. Throughout the course you'll learn, explore and gain practcal experience working with best practices for writing great programs in Java, using test-driven development techniques. This course quickly introduces you to the core features and benefits of JUnit. You''ll leave this course armed with the skills required to leverage solid TDD practices using the latest industry techniques and best practices.

Course Objectives

This skills-centric course is about 50% hands-on lab and 50% lecture, designed to train attendees in core TDD skills, coupling the most current, effective techniques with the soundest industry practices. Throughout the course, students will work on a project with labs specifically oriented towards using TDD to implement a complex and multi-faceted web application that uses a database in its final form.

Working in a hands-on learning environment, guided by our expert team, attendees will learn to:

  • Understand JUnit.
  • Understand and use the JUnit Test Runner interface.
  • Use JUnit to drive the implementation of Java code.
  • Test applications using native IDE support.
  • Best practices and patterns for test development.
  • Understand JUnit’s strengths and weaknesses
  • Understand the role of debugging when done in conjunction with tests.
  • Understand not only the fundamentals of the TDD using Java, but also its importance, uses, strengths and weaknesses.
  • Understand how JUnit affects your perspective on development and increases your focus on a task.
  • Learn good JUnit coding style.
  • Create well-structured JUnit programs.
  • Compile and execute programs using JUnit, jWebUnit, and DBUnit using the IDE of your choice.
  • How to extend testing with mock objects using EasyMock.
  • Look at refactoring techniques available to make code as reusable/robust as possible.
  • Discuss various testing techniques.
