In our previous article, we focused on documenting the best testing setup for frontends, which used Playwright and Next.js. You can check out the repository here where you can find the full setup.
In our experience, the best testing strategy for modern frontends is a combination of E2E testing (using Playwright+NextJS), and unit testing. Visual regression testing is not worth the effort in our opinion, especially with the advent of better CSS tooling like TailwindCSS and Vanilla Extract.
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.
With better CSS approaches like TailwindCSS and Vanilla Extract (which we're heavily using) it's much easier to maintain the UI and make sure it doesn't change unexpectedly. No more conflicting CSS classes, much less CSS specificity issues and much less CSS code in general.
With the advent of tools like Puppeteer and now Playwright, end-to-end testing has become much easier and more reliable. For anyone who's used Selenium in the past, you know what I'm talking about. Puppeteer has opened the way in terms of E2E tooling, but Playwright has taken it to the next level and made it easier to await for certain selectors or conditions to be fulfilled (via locators), thus making tests more reliable and less flaky. Also, it's a game changer that it introduced a test-runner - this made the integration between the headless browser and the actual test code much smoother.

With Vanilla Extract you can be sure that if you remove a CSS class, it's not used anywhere else in the codebase. It's been a game changer in terms of CSS maintainability and productivity for us at Infinite Table.
