Testing React: A Convert’s Journey from Enzyme to Testing Library

TestJS Summit is getting back in 2023 in hybrid format with the first in-person day streamed from the Berlin venue including hybrid networking features and interactive entertainment; and second day, as well as the numerous free workshops, streamed to the global audience online.

TestJS Summit is event for QAs and software developers to get up to date with JS testing best practices, sharpen skills and get latest updates from top products core teams. Get a full ticket to participate in workshops, and network with others JS testing folks on December 7-11, 2023.

React Query and Auth: Who is Responsible for What?

Get ready for an annual deep dive into the latest trends in React and Web development. Learn from engineers behind the framework ecosystem and early adopters at the main React Conference in the UK.The concept of the event is both about covering all you need to catch up on in the React ecosystem, combined with deep technical exploration of the latest architectural trends, new feature adoption, and efficient ways to solve complex problems.Engage in discussion rooms, hallway track with experts, hands-on practical workshops, and tens of insightful talks. Engineers of any level are welcome but be prepared for hardcore.

Automated accessibility testing with jest-axe and Lighthouse CI

TestJS Summit 2021

Do your automated tests include a11y checks? This workshop will cover how to get started with jest-axe to detect code-based accessibility violations, and Lighthouse CI to validate the accessibility of fully rendered pages. No amount of automated tests can replace manual accessibility testing, but these checks will make sure that your manual testers aren't doing more work than they need to. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

React Query manages server state on the client, and auth manages user sign in/sign up/sign out. Where do these two overlap, and how do you separate concerns? This talk proposes a data flow with custom hooks for both auth and React Query to manage authentication status and user profile updates.

Even if you're a regular expression pro, it's not always easy to know how to apply them in JavaScript. What's the difference between RegExp.prototype.exec and String.prototype.match ? What if I want to replace all punctuation followed multiple spaces with the same punctuation followed a single space? This workshop will explore the various methods and leave you with sample code, a cheat sheet, and the confidence to choose the right method for the job. Prerequisites:Node 12+Array methods: map and filterKnowledge of regular expression syntax helpful but not required Workshop level:JS devs who avoid regular expressions because who has time to figure out which method to use? Level: beginner / intermediate. <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>

Testing Library's advantages over Enzyme for testing React: - Opinionated framework enforces best testing practices (test behavior, not integration) - Opinions on how to find elements ( role) encourages accessibility - jest-dom assertions lead to simple, readable tests - ESLint plugins help encourage best practices in real time - test output helps locate elusive elements There will be a few code examples, but this is largely a discussion (rather than a how-to). <a href="https://www.froala.com/wysiwyg-editor?pb=1"> </a>
