red-green-tdd-trainingTest-Driven Development (TDD) is a design engineering process that relies on a very short development cycle. A TDD approach to software development requires a thorough review of the requirements or design before any functional code is written. The development process is started by writing the test case, then the code to pass the test and then refactoring until completion. Benefits of a TDD approach to software engineering include faster feedback, higher acceptance, reduced scope creep and over-engineering, customer-centric and iterative processes, and modular, flexible, maintainable code.

This 3-day instructor-led course is a deep dive into TDD that incorporates the steps that are necessary for effective implementation. Participants will cover Unit Tests, User Stories, Design, Refactoring, Frameworks, and how to apply them to existing solutions. In addition, this course explores the implications of code dependencies, fluid requirements, and early detection of issues. This is an interactive class with hands-on labs. To get the most out of this course, students are encouraged to fully participate. This course demonstrates the skills developers and teams need for building quality applications sustainably, with quality, for the life of the code base.

Part 3: Test Driven Development

Essential TDD techniques require developers write programs in short development cycles, and there are critical steps that must be taken. Tests are created before the code is written. Once the code passes testing, it is refactored to adhere to the most effective and acceptable standards.

    • Continuous Integration
  4. Eight Wastes of Software Development
    • Ripple effect of defects
    • Partially Done Work
    • Extra Features
    • Relearning
    • Handoffs
    • Task Switching
    • Delays
    • Defects
  5. Test Automation
    • Automate, Automate, Automate
    • Automate Early and Often
    • Additional Topics Identified

Lab: Test Driven Development

  • Start Test Driven Development on our example App
  • Write unit test cases

Part 4: Principles of Agile Development

TDD is directly influenced by design, so it will be a priority to take this into context during implementation. Considering design principles will enable teams to experiment with different approaches, and gear towards more functional programming.

  1. Design Principles Overview
  2. Coding Principles
  3. isolation of the SUT
  4. Developing independently testable units
  5. Test doubles
    • Introducing test doubles

  • Setting up Test doubles for our example app
  • Discuss and implement test dummy and test stubs

Part 5: Refactoring

Refactoring is another essential technique of TDD, and most software development teams are most likely doing some form of refactoring regularly. Refactoring can be used in a number of different workflows which will be explored in this Part.

  1. Why Refactor?
    • Red, Green, Refactor
    • Benefits
    • Development without TDD
  2. Refactoring Methods
  3. Refactoring Cycle
    • Reduce Local Variable Scope
    • Replace Temp with Query
    • Remove Dead Code
    • Extract Method
    • Remove Unnecessary Code

Lab: Continue our example project

  • Implement new test cases
  • TDD Cycle
  • Discuss and implement Refactoring Needs

Part 6: Pair Programming

Pair Programming is an effective way to improve code quality. In this Part, we will discuss pairing and how it leads to better software design, and a lower cost of development.

  1. Pair Programming
    • Pairing Setup
    • Results: Time
    • Results: Defects
    • How it works
  2. Advantages of Pairing
    • Both Halves of the Brain

Part 7: Acceptance Test Driven Development (ATDD) & Behavior-Driven Development (BDD)

Acceptance Tests are an important form of functional specification, and Behavior Driven Development dictates what happens as an effect of these tests being run. In this Part, we will cover the difference between them, and how they are closely related.
