Designing Effective Tests with React Testing Library

The instructor is Josh Justice, who goes by CodingItWrong online.

The primary focus is on designing effective tests using React Testing Library, including live coding, exercises, and sharing useful resources.

Attendees can find more information and resources at codingwrong.com, which is mentioned in the footer of all the slides.

The workshop discusses React Testing Library, user event library, Jest, and various tools and approaches for mocking web service requests.

Josh Justice suggests using Mastodon for social media interactions and can be found at [email protected].

The philosophy is to write tests that resemble how users interact with the application, focusing on testing the contract of components rather than implementation details.

Josh Justice has written a book on test-driven development with React Testing Library, which includes free introductory chapters and is available with a discount code for workshop participants.

Josh Justice works for Test Double, a consultancy focused on improving the world's software by embedding developers with teams to improve software quality.

Josh Justice provides a personal Discord community, a newsletter from Test Double, and various social media channels like Mastodon for staying updated on React and testing.
