Spend the Day Immersed With a Leading JavaScript Master

Building and deploying web applications with confidence is challenging. Verifying that what you’re deploying to production actually works requires a solid suite of automated tests. Knowing how to configure tools and write tests that enhance your development experience is vital to your success.

In this class, we’ll explore the merits and tradeoffs of different forms of testing and get into configuring and using specific tools to increase confidence in deploying our applications.
Join Kent C. Dodds and learn invaluable skills you can take back to improve your JavaScript applications.

How We'll Spend Each Day

We’ll start out with a discussion of the history of testing in general and in JavaScript and establish the purpose and role that testing plays in our application development workflow. Then we’ll get into the various forms of testing, the merits and tradeoffs of each form. We’ll also talk about different styles of testing (like TDD vs BDD). And we’ll define some of the vernacular of testing (like code coverage).

Then we’ll jump into the hands-on portion. We’ll cover unit, integration, and E2E testing in this workshop. With the “Conduit” app, we’ll start out setting up the tooling for unit testing the Node API server. We’ll write some unit tests together and have time to write some individually. Then we’ll do the same for some of the frontend React app.

Then we’ll contrast that experience by writing integration tests for our application. Finally we’ll set up for our application and write E2E tests. Throughout the whole experience, we’ll learn the value and trade-offs of each form of testing, where mocking is appropriate/useful, how to avoid testing implementation details, and more.

We've already held over 50 workshops holding thousands attendees in-person and online. In this time we've discovered ways to schedule the day so it goes smoothly and efficiently.

  • 9:30am – Tech Check and Hello

Is This Workshop For Me?

This class is for experienced JavaScript developers who have at least some experience in testing web applications. This workshop will give you valuable insights you can use in testing your own applications.


You’ll need to have a good grasp of JavaScript syntax (experience with modern JavaScript features and syntax will be valuable as well). Also having experience testing non-trivial JavaScript applications will help you understand the importance of some of these concepts. Please see the project repository README for system requirements and setup instructions.

What Past Attendees Are Saying

"Superb presentation from a genuine domain expert. I learned a ton today."

Steve Jakubowski

"Keep up the good work. I've attended a lot of online workshops, and they are very shallow and unpractical. Most of the time, online people are treated as second class, but still paying citizens. Here we get all the content and get to participate as well (if only there was a way to get those cookies...)."

Adrian Murillo

"The class was great. It was really cool to get a bunch of links to example code to look at during the presentation and after the class."

Nate Yourchuck

"Good location and facility. Great technology for capture, presentation layout and video streaming. Really excellent being able to view the videos afterwards. It takes away the sense of having to absorb everything immediately or else lose it into the ether. It was fun. What more can you ask for?"

Laurence Bates

"Really well run...loved the communication pre-event. Very impressed with everything...this was my first online conference purchase, but I would definitely consider doing it again."

Jeff Sims

"I really enjoyed the online workshop experience. It is much better than just watching videos. I was able to participate in the conversations and benefit from other folks' questions."

Dana Greenberg

"You guys did a really great job! I cannot say enough good things about the experience."

Richard Ranke

"Everything was first class: excellent instructor, material, video, moderator, audio. Thank you!"
