Cross-platform, cross-browser screenshot testing for modern user interfaces.

In May - June 2021, WebAIM surveyed preferences of screen reader users. We received 1568 valid responses. This was a follow-up to 8 previous surveys that were conducted between January 2009 and September 2019.

The Cypress team maintains the Real World App (RWA), a full stack example application that demonstrates best practices and scalable strategies.

When testing svelte components in a node environment and using them outside of a Svelte application, we will be mostly interacting programmatically with Svelte’s client-side API as well as the helpers found in @testing-library/svelte.

Mock by intercepting requests on the network level. Seamlessly reuse the same mock definition for testing, development, and debugging.

Creating digital experiences that can transform your company takes data-driven decisions, continued experimentation and constant invention. We’ve been doing some re-inventing of our own.

Speed up testing with Jest and Spectator for Angular applications.

The console panel in your favorite browser's DevTools can be a very powerful ally when troubleshooting problems in a web app. Log data, send requests, manipulate DOM elements, you name it, the console can do it all!

Just like its predecessor, Angular 1, Angular has been designed with testability as a primary goal.

When we talk about testing in Angular we are usually talking about two different types of testing:

Unit Testing
This is sometimes also called Isolated testing. It’s the practice of testing small isolated pieces of code. If your test uses some external resource, like the network or a database, it’s not a unit test.

Functional Testing
This is defined as the testing of the complete functionality of an application. In practice with web apps, this means interacting with your application as it’s running in a browser just like a user would interact with it in real life, i.e. via clicks on a page.

This is also called End to End or E2E testing.

I’ve been writing end-to-end tests for the place I work at, which has its main product written in Google’s AngularJS. The dedicated E2E testing framework for AngularJS is the Protractor framework. While it’s a nice project, the documentation is a bit terse at times, and a lot of my understanding came, unsurprisingly, from Stack Overflow. Here are some of my key learnings, also for future reference. Some of it may seem a little obvious, but my experience with JavaScript doesn’t go much further than <script>alert('Hello World!')</script> so bear with me here.

How to automate testing your Storybook?
An excerpt from Design Systems for Developers.

When design systems are the source of truth and subscribers have easy access to code, it's important that code is well-tested. Lindsey shares how we unit test our Sass and how you can too.

The new way to design, develop, and deliver software with confidence.
