Introducing the Red-Green-Refactor Workflow

This chapter introduces the Red-Green-Refactor workflow, which is at the heart of Test-Driven Development (TDD). You’ll use it to write a first Svelte component, including a unit-test suite that specifies the behavior of the component.

This workflow benefits you because it provides a structure for implementing software. It makes it less likely that you’ll implement the wrong thing. It also helps you to avoid overcomplicating solutions.

This chapter covers the following topics:

  • Understanding the Red-Green-Refactor workflow
  • Thinking ahead with up-front design
  • Writing a failing test
  • Making it pass
  • Refactoring the tests
  • Adding styles to the component

By the end of the chapter, you’ll have written your first pieces of Svelte functionality using TDD.
