I've been exploring testing setups for both personal projects and work, particularly focusing on whether to transition from jsdom to vitest's browser mode. After several tests, I found that vitest's browser mode is often faster than jsdom, and it really enhances the developer experience when debugging tests. Plus, it allows for better accessibility testing without needing to mock things like localStorage. Given these points, are there any reasons to continue using jsdom or happy-dom instead of switching to vitest's browser mode?

I think you're right to lean towards vitest browser mode. Honestly, there doesn't seem to be a reason to stick with jsdom anymore. People are just slow to adapt, but the benefits of using a real browser environment are too good to pass up.
Totally! Many still assume that a real browser is much slower, but that's really not the case.
