Test Driven Development (TDD) is one of the core practices of Agile software development. Many companies have realized the benefits of using this technique to write code. However learning how to TDD is not always easy, using it on the existing system can be even harder.This two-day program provides a highly interactive exploration of unit test automation, principles and practices.  Participants will learn the main difficulties of using these principles in a live system, the main strategies for tackling such a task and how one can practically start writing those tests.

Objectives

• Writing basic unit tests using.
• Learning principles of Test Driven Development.
• Experience Best Practices of unit testing.
• Understanding the difference between unit tests and acceptance tests.

• Writing basic acceptance tests.
• Understand the principles of Isolation using modern isolation frameworks.
• Learn how to write code without breaking the system.
• Learn how to leverage frameworks to ease authoring of tests
• Real Life examples.
