Java Training : Introduction to Java Testing Version 8.0

Introduction to Java Testing

Java Training Overview

This course introduces the experienced Java programmer to testing and test-driven development practices using JUnit. We work from the basics of JUnit as a tool, to best practices for writing effective and maintainable tests. The course is not strictly a TDD course, but we introduce TDD and take students through an illustrative case study. We discuss the importance of mocking and explore testing techniques using Mockito. Finally we discuss concerns and strategies for testing enterprise components in the Java EE context.

Java Training Learning Objectives

Build unit tests for Java classes using JUnit.

Write effective tests, and design classes for testability.

Understand test-driven development (TDD) and use dynamic mocking to support isolated testing.

Develop effective testing strategies for Java-EE components.

Java Training Prerequisites

Solid Java programming experience is essential -- especially object-oriented use of the language. Language features and techniques that are integral to some lab exercises include interfaces and abstract classes, threading, generics and collections, and recursive methods.

Java Training Course duration

2 days.
