Over the past few weeks, I’ve been receiving a lot of requests on my TikTok channel (@jsmentoring) about creating a comprehensive JavaScript testing tutorial. Many of my followers, ranging from beginners to advanced developers, wanted to understand the nuances of testing in JavaScript. After listening to your feedback, I decided to create a full tutorial that covers unit testing, mocking, asynchronous testing, and more!
I’ve shared the entire tutorial on GitHub, making it accessible for everyone to follow along. The tutorial includes step-by-step guides and practical examples using Jest, a popular testing framework for JavaScript. You’ll learn how to test everything from simple functions to complex React components.
What you can expect:
- Unit Testing: Basics of testing individual functions and components.
- Mocking and Spying: Learn how to mock external functions and dependencies.
- Asynchronous Code: Test asynchronous functions like API calls or timeouts.
- React Testing: Understand how to test React components and their state.
- Advanced Techniques: Explore testing with Redux, performance testing, and more.
To make it even easier for everyone, I’ve been posting short video snippets on TikTok to give quick insights and tips on JavaScript testing. If you’re not familiar with my TikTok content yet, check it out here: @jsmentoring. It’s a great way to get a taste of the tutorial before diving into the full guide.
What do you think about learning through short TikTok videos?
Would you prefer more bite-sized tutorials or longer, more detailed guides? Let me know your thoughts, and I’d love to hear how you approach JavaScript testing in your projects!
💡 Quick tip: When testing JavaScript functions, always start with simple unit tests, and gradually increase the complexity as you dive deeper into your application’s behavior. This will ensure that your tests are both effective and easy to maintain.
This whole process has been an amazing way to communicate and connect with people through TikTok. Initially, I wanted to create more advanced lessons on algorithms and concepts for companies like Fancy or other high-level topics. However, as I started receiving more questions from followers, I realized that testing was a much bigger area of interest for many developers. This shift made me realize how powerful it is to listen to your audience and cater to what they need. It's clear that testing is something people want to dive deeper into!
You can find the full tutorial and the GitHub repository here. I hope it helps you improve your testing skills, and feel free to ask questions if anything is unclear!
