Issue:

There's a "tip" over at https://vitest.dev/guide/testing-types.html#run-typechecking, saying:

When using @ts-expect-error syntax, you might want to make sure that you didn't make a typo. You can do that by including your type files in test.include config option, so Vitest will also actually run these tests and fail with ReferenceError.

After adjusting the test.include array in vitest.config.ts, I cannot make all my tests work.

There are 3 test files to present the issue:

• test/repro-control.test.ts
  • this is a non-type test, to make sure normal tests still report issues
• test/repro-legit-fail.test-d.ts
  • this is a legitimate type issue, Vite type testing should report this
• test/repro-typo-fail.test-d.ts
  • this is the mentioned "typo" issue, according to the tip Vite should report this as producing a ReferenceError

There are 2 npm scripts

• npm run test
  • this is what I believe I should write, utilizing --typecheck, after reading the docs
• npm run test-no-typecheck
  • but to make sure the issue is not the --typecheck flag, there's also this script

Upon running npm run test, the results are:

• ❌ (FAIL) test/repro-control.test.ts
• ❌ (FAIL) test/repro-legit-fail.test-d.ts
• ✅ (PASS) test/repro-typo-fail.test-d.ts

Upon running npm run test-no-typecheck, the results are:

• ❌ (FAIL) test/repro-control.test.ts
• ✅ (PASS) test/repro-legit-fail.test-d.ts
• ❌ (FAIL) test/repro-typo-fail.test-d.ts

What I would expect, is for at least one of the npm scripts to result in every test failing.
