Test Driven Development

Overview

TDD Workshop is a 3 day course designed to teach you the principles and practice of Test Driven Development. During this course, we will be sharing our real world experience and will go through several examples and actual project scenarios and you will learn how to drive your code using tests, how to write better tests and how you can use tests to minimize cost of change even in late stages of the project.

Description

TDD is accepted as the most effective method to write code. Tests are requirements that the software should satisfy and the developer has to implement a test before he writes production code. Benefits of TDD are as follows:

  • TDD makes design loosely coupled and highly cohesive and prevents design flaws.
  • You discover problems in understanding requirements early on.
  • Bug risk is minimized by a factor of ten which is proven by empirical studies.
  • Test-Code-Refactor cycle keeps concentration of developers at a high level.
  • Minimizes of cost of change , requirement changes can be implemented at a minimum cost even at late stages of development.

Trainer

Prime Technology Agile Coach, Cenk Çivici has been working with Agile methodologies for over 10 years and is the most experienced coach in Turkey. He has worked in several projects during his consultancy years at Thoughtworks US and UK and found the chance to work with many thought leaders in the Agile community. He has trained over hundreds of people in Agile practices and always follows a fun, hands on training approach and dislikes powerpoint slides.

Prerequisites

Experience in Object Oriented Languages such as Java, C#.

Course Outline

Overview of TDD
