More and more organisations are looking to Test Driven Development (TDD) and related practices, as a way to gain or maintain their competitive advantage in software delivery. In this intensive program, participants learn principles of TDD. Primary focus of program is to allow participants to apply unit testing with frameworks collectively known as unit testing frameworks to adopt test-first method of coding. Participants will learn practices to allow writing solid and reliable code efficiently using TDD. ‘Unit testing framework’ refers to any of popular unit testing frameworks with architecture similar to Junit/TestNG for Java and Nunit/Xunit/MSTest for .Net. Similarties between such unit testing frameworks is also well explained. Javascript Unit Testing is demonstrated with Jest/Jasmine. Program includes many demonstrations. All demonstrations will be good for programmers knowing any object oriented language like C#, Java, Javascript, python etc. Mocking is explained in details with relevant frameworks. Participants will have hands-on during program with their choice of unit testing framework. On top of this, program includes topics like OO design principles, SOLID, GRASP, Refactoring, Pair Programming, introduction to Patterns, and Role of TDD in Agile Development. Beyond basic contents, program introduces concept of Behavior Driven Development (BDD) and Acceptance Test Driven Development (ATDD).

Audience

Program is primarily for developers and designers that are directly involved with source code.

Prerequisites

Participant must be able to code simple application with standard library using their choice of IDE and language (C#, Java, Javascript, Python).
