3 Days

Description

NOTE: This course is only available by customer request. If you are interested in taking this course, please call 651-905-3729 or submit a request for a date.

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.

This 3-day instructor led course is a deep dive in to 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.

Objectives:

Implement Unit Testing in software development and testing
Write effective Unit Testing
Use mock objects to isolate the “system under test”
Effectively refactor your codebase
Aid in the successful adoption of Test-Driven Development using proven techniques and practices
Use Acceptance Testing and Behavior-Driven Development to further advance Test-Driven Development

Audience:

Professionals who may benefit include:

Software Developers and Programmers
Agile Practitioners
Quality Assurance Professionals
Software Testers
Product Owners
Project Managers
IT Managers
Software Engineers

Course Overview

Module 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. Module 1 serves as a leveling exercise to ensure that team member are 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
Module 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
Module 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
- TDD Benefits
Sustainable TDD
- Development without TD
- Test Last
- Test Last in Parallel
- Test Driven Development
Supporting Practices
- Collective Ownership

- Relearning
- Handoffs
- Task Switching
- Delays
- Defects
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
- Experience RED, Green, Refactor Process
Module 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
Module 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 module.
Why Refactor?
- Red, Green, Refactor
- Benefits
- Development without TDD
Refactoring Methods
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
Module 6: Pair Programming
Pair Programming is an effective way to improve code quality. In this module, we will discuss pairing and how it leads to better software design, and a lower cost of development.
Pair Programming

- Results: Defects
- How it works
Advantages of Pairing
- Both Halves of the Brain

Module 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 Module, we will cover the difference between them, and how they are closely related.
