       * By default, vitest runs typecheck on tests matching the pattern "*.test-d.ts".
       * Sadly some IDEs (like Webstorm) doesn't work well with custom patterns like that.
       * They do not properly recognize globals like vitest ones (describe, it, expect, etc.).
       * Because of that, we include typecheck in all test files.
       * The performance impact is minimal, and it makes the IDE work properly.
