Title

T201: Agile Testing for Java™ Developers

Duration

2 Days

Audience

Software developers

Prerequisites

Knowledge of the Java™ programming language. Some knowledge of object-oriented design is helpful.

Objectives

Arm the developers on your team with the best practices, patterns and tools (many of them free) for delivering error free code.

On completion of this course developers will write code that is more often correct, simpler, more maintainable and just plain better.

Description

This course introduces developers to techniques, tools, and patterns for using testing to deliver good, defect-free code as fast as possible.

There are a great number of tools and practices for delivering defect-free code available to Java™ developers. Many of the tools are free but poorly documented and it is not often obvious how best to use them together. This course introduces the best and most useful tools and practices, where to apply them and how to use them. Some tools include JUnit, Cactus, EJBUnit, HTTPUnit, Clover, Jester, MockMaker, EasyMock, JFCUnit, Jemmy, Abbot, NoUnit, JUnit-addons, JUnitPerf, Enhanced JUnit, DBUnit, SQLUnit, FIT, FITnesse, WATT, ANT, Test Mentor, and JTest.

This course also introduces an important technique called Test-Driven Development, which enables developers to write the tests that prove their code is correct before they write their code. Test-driven development is more than a testing technique. It is a way to drive design and implementation from the point of view of implementing running code that satisfies the tests. You will learn to use Test-driven development to rapidly evolve well-designed, easy to maintain code.

Skill level
