April has come to an end, and what a fantastic month it was! I had a great time learning about Signals, Angular 17, and the future of testing. Let's take a look back at the highlights and fun moments.

## 👋🏼 Bye Bye Karma! Hello Web Test Runner and 🦥 DeferViews

* I explored how to improve the performance loading dynamic components using DeferViews in Angular.

* Thanks to a great talk with @[Rainer Hahnekamp](@rainerhahnekamp) , I learned about the future of testing in Angular and started to play with Web Test Runner.
