Describe the Bug

Context

I wrote a script (.ts file) to fetch and parse some data from Notion during build time. I wanted to test my parser, so I installed vitest and made a .test.ts file. However, this creates a bunch of errors when I run yarn dev. This doesn't seem to prevent the dev server from starting/running, nor does it affect the build.

Questions

• Is it possible to ignore files (like **/*.test.ts) during Astro builds?
• Do these scripts get shipped to the user?
• Is it related to this issue: Vitest fails to import under Vite App vitest-dev/vitest#1118?
• Is there official guidance on writing tests in Astro projects?

Error output

[vite] error while updating dependencies:
