Alright the Windows issues are finally resolved. @mrginglymus could you do one final check with https://pkg.pr.new/vitest@12d473c and equivalent preview packages with your real-world project?

On Windows the root is here D:/a/vitest/vitest/test/coverage-test while filename is /D:/a/vitest/vitest/test/coverage-test/fixtures/src/untested-file.ts.

@AriPerkkio yes this is working correctly on my real-world project. Thanks so much for the effort in fixing this!

Looks good to me 👍
How did you eventually fix optimize deps error? Is it by switching vitenode.transformRequest with browser.transformRequest #7597 (comment)?

How did you eventually fix optimize deps error? Is it by switching vitenode.transformRequest with browser.transformRequest #7597 (comment)?

Switching to vitenode.transformRequest is a way to avoid it, yes.

But when using browser, this change was enough to fix it. And when doing parallel requests, it was important not to reset noDiscovery back.

+ browser.config.optimizeDeps.noDiscovery = true
const result = await browser?.transformRequest(filename).catch(() => null)

Setting the server.preTransformRequests had no effect at all - Vite was still following dependencies of requested modules. 🤷

hi-ogawa · 2025-03-13T07:23:26Z

But, if this relies on vite node's server and browser mode's server being different, would it potentially block the plan of merging the server? #6912

How does it matter though? The code output is the same, isn't it what matters here?

hi-ogawa · 2025-03-13T23:24:08Z

I thought the difference is vite-node's server explicitly configures optimizeDeps.noDiscovery: true + preTransformRequests: false, but browser's server has opposite (i.e. normal Vite app default).

Yes, but does it matter for coverage what these options are?

I would imagine transformRequest output is same, but as Ari said #7597 (comment), without noDiscovery, Vite server would eagerly crawl and potentially trigger optimize deps, so such side effect is not ideal for our usage of transformRequest for coverage.all.
(actually I don't know what's bad about this, but at least, optimize deps might show odd error/warning from esbuild?)

I think it's good to land with vitenode.transformRequest, but we might need to revisit this when #6912. I don't know whether we need something new from Vite or we can use extra inline environment for this transform, or something else.
