The Call Kent Podcast ·

2025/02/20

I’d love to hear your thoughts on mutation testing when applied to components. In my experience, it doesn’t seem to make much sense because it often reports that tests still pass after altering aspects that aren’t relevant to the component’s behavior. To me, this type of testing seems more suited for pure unit tests. What’s your perspective on this?Make your test fail Should I write a test or fix a bug?

What are your thoughts about Qwik and hydration?

The Call Kent Podcast ·

2025/01/08

What do you think about resumability and Qwik? About 9 months ago, there was talk about Wiz and Angular working more closely together (Wiz was the tool that inspired Qwik). But Angular only committed to working on partial hydration support, not the full resumability like Qwik. So do you think React developers should care about this? If so, should they use partial hydration tools like Astro today or wait for something like resumability to be added to React? 𝕏 Post What are your thoughts

Does the testing trophy need updating for 2025?

The Call Kent Podcast ·

2024/12/09

In 2024, we live in a world where the defacto for creating React applications is SSR (e.g. Remix, react router v7, Next, TanStack). Coupled with the rise in performance, reliability and reduction of cost in running e2e tests by playwright and now vitest's Browser Mode, is it time to consider reworking the Testing Trophy to make e2e tests the largest proportion of the trophy?This is starting to make more and more sense to me as e2e tests are becoming as cheap to execute as integration

React Components vs Progressive Enhancement

The Call Kent Podcast ·

2024/06/19

Hi, Kent, my name is Alex. On one hand, you advocate for implementing Progressive Enhancement technique for applications. On the other hand, even in Epic Stack, the use of custom React components is justified, even for a simple checkbox, which essentially makes the application non-functional without JavaScript. So, I'm struggling to decide whether it's worth trying to develop a Progressive Enhancement UX at this time or if it's still an unattainable ideal.Kent Dodds - Bringing Back

Do generated types from OpenAPI spec change testing?

The Call Kent Podcast ·

2024/04/29

Hey Kent! I've been thinking about something lately. I've worked at a number of different sass companies and something that is always an interesting problem is how we end-to-end test a software application that has a UI. I love the idea of testing for confidence and, to that end, I've been wondering how we might begin to shift our thinking about confidence testing when we use some communication protocol, like GRPc or OpenAPI to and use those protocols to generate things like static
