Course Description

Accelerate your journey from Noob to Pro with real-world Test Driven Development. See how to gain all the benefits of Test Driven Development to speed up and secure your development process.

Led by a professional software engineer, using practical examples, this course will make it easy to write tests during software development, and get better code, without slowing down your development cycle.

Rather than walking through the syntax of the test tooling, this course is intended to put Test Driven Development in context. We will discover when to use certain techniques based on realistic scenarios. This connects the theory with the value of applying it.

This is aimed at people who need to add more test automation to their workflow. We will see how to do this with purpose and style. We will learn how to avoid pitfalls and make sure we're testing the right things.

Topics include:


  • Why we need tests

  • The basics of tests, from setup through to assertions

  • Red/Green/Refactor

  • Code coverage

  • Mocks and Test Doubles

  • Testing code that depends on APIs

  • Keeping control of test code

  • Test first with user interfaces

Though the examples use Vitest, they can also be adapted to their equivalents in the Jest framework.

Even with some experience in Typescript and Vitest, this course taught me loads of extra tricks I never would have picked up otherwise. The examples were great and the content was broken up really well. Loved it!

Excellent entry level for TDD. Uses good, real-world examples to show you how to use tests to build your understanding of the problem as you build your code

By Ashraful Hasan on 6/22/2024

The course contains the details I need as a beginner. The instructions are clear and the presentation is very engaging. I always found TDD to be difficult to start and this is the first time I feel like I am confident and I know what I am doing and why I am doing.
