Testing LiveView

LiveView is an amazing tool for building interactive applications. It has changed my approach to building rich UIs completely.

But testing LiveView apps requires us to learn how to use a new set of tools. And as with all new tools, we need to learn how to wield them well.

LiveView tests use a proxy process to act as the browser. That has benefits like running tests extremely fast without running JavaScript for our tests. 🥳

But it also makes it easy to write specious tests — tests that seem correct but actually fail to test large portions of our LiveView code. Those tests mislead us into thinking our app is covered, but production is completely broken! 😱

That's why I not only teach the mechanics of writing LiveView tests (the how) but also how not to write LiveView tests. What's more, I teach the logic behind why we write tests in specific ways so you're ready to apply the same logic in your own application.

Highly recommend this course! German is my go-to for LiveView testing, and I’m thrilled he took the time to create this comprehensive, thoughtful course.

A course that makes an impact on your professional life...

Each lesson is crafted from my experience testing LiveView applications in the wild and refined by my ten years of experience practicing test-driven development.

Once I teach you how to think about writing LiveView tests, you'll be able to apply the same logic to other testing challenges you face in the real world.

You'll learn to write fast, robust, and easy-to-maintain LiveView tests — the kind of tests that give you confidence when deploying to production.

Took the course to improve @indiepaperme and check out if LiveView was ready for production. Ended up converting all pages to LiveView all covered by tests and production patterns I learnt from the course.

10/10 Recommended for LiveView.

... and one you'll actually finish

As a software developer, I know how difficult it is to keep up with all the latest tools with limited time.

But so many programming courses don't give you a good return on your time investment. You sit through hundreds of hours of materials that you soon forget and never apply at work. Or worse, the course is so long you never even finish it! 🤦

That's why I've taken a lot of time to distill each lesson into its essence. There are no fillers or fluff.

@germsvel's "Testing LiveView" #elixirlang #phoenixframework course is really great. Tons of actionable info, and zero fluff.

Watch it once. Reference it forever.

Of course, we don't always retain what we learn perfectly.

In those cases, it's helpful to come back to the source to reinforce what we've learned. But that can be tough with videos. Will you have to watch everything again?

You can certainly do that if you want. But it's faster to skim and search text. That's why each lesson includes detailed summaries so you can always find what you need quickly.

It's a golden reference for testing LiveView!

I don't usually shout out, but testing live view by @germsvel is a great reference when testing.

Going into this I thought $100 is a bit much, but now I can see how much work went into this making it all simple and easy to understand.

Totally worth it.

You've struck a great balance between showing how to write tests and application without getting sidetracked with other app details. You've upgraded my skills. Thanks again!

This was the biggest instructive course I've learned in my elixir journey. Thank you so much for all your efforts

— Shahryar Tavakkoli

Hot damn! This was a thorough, amazing and thoughtfully organized course! Amazing work. Much respect.

— Benjamin Shepard

I can't thank you enough for the course! It's allowed me to get comfortable with Elixir and Phoenix LiveView quickly as my career shifted from data science (C++, Python, R) to web-app testing & development.

"But what if I don't learn how to test LiveView?"

That's a fair question.

I truly believe this course will teach you how to test LiveView effectively. But, hey, I've been wrong before. 🤷

That's why I offer my Learn to test guarantee!

Learn to test guarantee

If you don't learn how to test LiveView by the time you finish the course, I will give you a full refund.

If you don't learn, I don't earn.

So, what do you have to lose? Get the course now!

About Me

German Velasco

I'm a software developer who's been practicing test-driven development for a decade.

You might recognize me from my one of my short video tips I share weekly , my Testing LiveView ElixirConf talk , my TDD Phoenix book , or one of my blog posts .

For the past six years, I've been helping clients deal with slow test suites, intermittent failures, difficult test cases, and more.

Testing is my passion. I love thinking about it, iterating on practices, and figuring out how to write tests that are valuable, stable, and easy to maintain.
