We use Jest Framework for testing. Jest is not a dogma, and, of course, in its place can be any other test runner, such as Mocha or Ava. Let's focus on tests. I'll provide a short example because I don’t want to waste your time. You can find the full version here. It's crucial to read the comments in the code below. Let's go!
Probably Enzyme was the first to popularize component testing in React by doing shallow rendering and expecting some things to be there in the React component tree. Then React Testing library came and took component testing to a whole new level.
React Testing Library
Jasmine is a behavior-driven development framework for testing JavaScript code. It's known for its clean, straightforward syntax and does not rely on any other JavaScript frameworks or a Document Object Model (DOM). Jasmine is often praised for its simplicity and ease of use in both frontend and backend testing environments.

Usually, I would let organic users be my load test. However, I am working on a project that has an anticipated load on a new-to-my-team stack, so I'm looking into ways to load test.
I've seen tools like k6 (https://k6.io/), Artillery (https://www.artillery.io), and JMeter (https://jmeter.apache.org/).
I've been using Artillery, but it's hard to visualize the results.

Using these reports, developers can prioritize accessibility fixes and improve their products' accessibility. Popular examples of automated testing tools include Axe, WAVE, and SiteImprove. Also, most modern browsers offer built-in accessibility audits within their developer tools.
Native code coverage via v8 or istanbul.

Dredd: used to test APIs based on the API blueprint or OpenAPI specification, to ensure implementation matches the specification.
Mocha can also run in the browser: https://mochajs.org/#running-mocha-in-the-browser. An alternative library that can also run in the browser is QUnit: https://qunitjs.com/. You can include both with

You can give a try about visual testing. I think about Cypress components and Cypress Image snapshot or Jest Image snapshot (not DOM testing)
