Test-Driven Development Workshop

Test-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.

Description

This 3-day TDD training course instructor is a deep dive in to Test Driven Development 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.

Who should attend

This class is designed for professionals who have experience in language programming, including C+ or Java. Specific titles of attendees include:

  • Software Developers and Programmers
  • Agile Practitioners
  • Quality Assurance Professionals
  • Software Testers
  • Product Owners

Outline: Test-Driven Development Workshop (TDDWS)

Part 1: Agile Overview Test Driven Development is a key component of the Agile Software Development Methodology and of the overall DevOps movement. So it is helpful to have at a minimum a high-level understanding of Agile practices and scrum ceremonies and TDD fits into the overall Agile, Scrum and DevOps landscape. Part 1 serves as a leveling exercise to ensure that team member is speaking the same language during upcoming labs and discussions.

What is Agile Software Development

  • DevOps Overview
  • The Agile Manifesto
  • Scrum vs Agile

Components of Agile

  • User Stories
  • Tasks
  • Bugs
  • Automated Builds
  • Automated Tests
  • Continuous Inspection

The Role of TDD in Agile Development

  • Automated Unit Tests
  • Automated Acceptance Tests

Lab: Explore the Board of an Agile Project

  • Kanban Board
  • User Stories
  • Tasks
  • Bugs
  • Work in Progress
  • Burndown Chart

Part 2: Unit Testing Unit Testing is a critical component of Test Driven Development (TDD). Small units of code are tested throughout the development process, which isolates functionality to ensure that individual parts work correctly.

Unit Test Fundamentals

  • Reason to do Unit Testing
  • What to Test: Right BICEP
  • CORRECT Boundary Conditions
  • Properties of Good Tests

Frameworks

  • What is JUnit
  • JUnit Building Blocks
  • Test Cases
  • Test Suites
  • Examples

Agile Testing Strategy

  • Agile Testing Quadrant
  • Automation Pyramid
  • Assertions

Test Attributes

  • Setup / TearDown
  • JUnit Lifecycle
  • System Under Test
  • Test Design Strategy
  • Naming our Tests
  • Exceptions

Lab: Introduction to Unit Testing

  • IDE and Project Setup
  • Running our first Unit Test
  • Explore Junit framework
  • Test Attributes
  • Assert Statements

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.

TDD Rhythm

  • TDD Overview
  • Red, Green, Refactor

  • Collective Ownership
  • Continuous Integration

Eight Wastes of Software Development

  • Ripple effect of defects
  • Partially Done Work
  • Extra Features
  • Relearning
  • Handoffs
  • Task Switching
  • Delays

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.

Design Principles Overview Coding Principles isolation of the SUT Developing independently testable units Test doubles

  • Introducing test doubles
  • Stubs
  • Fakes
  • Mocks

Lab: Continue development on example App

  • 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.

Why Refactor?
