Playwright (v1.31) introduces a new feature to make the authentication process easier. This approach unifies the authentication flow with the rest of the test cases, and more importantly makes it possible to test with different user roles.Angular standalone components and Angular Testing Library make component tests easier
Standalone components give you a better foundation to build on, as your Angular component becomes less affected by its internals. It doesn't matter if the component has its own template, or if it's using child components. This makes your test cases less brittle than before with Angular Modules. To interact with the component we're still using the Angular Testing Library because it provides useful utilities to interact and query the component.Invoke the Azure DevOps API from within your Azure DevOps pipeline

All these benefits, plus you'll see that it's fun to write tests in this way.Guarding your Angular modules 💂
A lot of Angular modules need to be imported with a static forRoot() function, via this function it allows us to configure the module. But sometimes we make the mistake to use the forRoot function more than once throughout an application. We might not notice it when this happens but often it is the cause of unexpected behavior, which is sadly hard to debug. In this post, we'll look into a solution.A little trick with Angular forms and directives 🃏

We had this problem and came up with the following solution.My love letter to XState and statecharts ♥
I discovered XState a year ago, I already had encountered state machines and statecharts before but I missed the point. Now a year further, I'm here to tell you that these are worth looking into and that XState is a the library to get you started. For me, the most important points to use XState or statecharts would be that it's declarative and explicit, it's hard to create invalid state. The nice extra's that you get with it, is the tooling around it and the portability across frameworks.Don't miss out on css variables
