how to generate sourcemaps for tests under _snowpack/link

[zanona]

I am using web-test-runner-plugin for running some tests but unfortunately, whenever having a failing test it points me to the correct file but with wrong line and column:

at o.<anonymous> (_snowpack/link/test/lib/catalogue.test.js:94:23)

The original file here should be under test/lib/catalogue.test.ts:104:3 in this case.
After checking the link at http://localhost:8000/_snowpack/link/test/lib/catalogue.test.js I could see that sourcemaps are not being generated even with snowpack.config.js having buildOptions.sourcemap:true and optmize.sourcemap:true as well?

Is it currently possible to have those transformed files having sourcemaps enabled so web-test-runner can point to the correct place?

Setting buildOptions should generate sourcemaps (not on disk; they're generated on the fly); that being said there are some problems (See #3381) with generating these pkg sourcemaps.

Right now it should work if you use sourcemap: 'inline' instead of buildOptions.sourcemap:true. You'll need to run snowpack build --rebuild to clear your internal cache though.

Your case may be a bit different since it's not in pkg subdirectory I'm noticing.

A further question: Why are your tests inside the snowpack meta directory at all?
