[Bug]: Validation warnings for options like preset or coverage directory

[MichaelBorde]

Version

29.3.0

Steps to reproduce

Use a jest.config.ts like:

export default {
  preset: './jest.preset.js',
  coverageDirectory: './coverage',
};

Expected behavior

Run tests using ./node_modules/.bin/jest without any warnings.

Actual behavior

● Validation Warning:

  Unknown option "preset" with value "./jest.preset.js" was found.
  This is probably a typing mistake. Fixing it will remove this message.

  Configuration Documentation:
  https://jestjs.io/docs/configuration

● Validation Warning:

  Unknown option "coverageDirectory" with value "./coverage" was found.
  This is probably a typing mistake. Fixing it will remove this message.

  https://jestjs.io/docs/configuration

Additional context

Might be related to the missing default option for preset or coverage in packages/jest-config/src/ValidConfig.ts.

Sorry about that! I'm fixing preset in #13583 as that's obviously a bug. However, e.g. testTimeout only works as global config, not as part of projects.

https://github.com/facebook/jest/blob/dfc87111e708b9294dc54ab0c17712972d042c1c/packages/jest-circus/src/legacy-code-todo-rewrite/jestAdapterInit.ts#L61-L63
https://github.com/facebook/jest/blob/dfc87111e708b9294dc54ab0c17712972d042c1c/packages/jest-jasmine2/src/index.ts#L43

It probably should be project config, but it's not. same with coverageDirectory and collectCoverageFrom at least. Not sure about reporters - that is probably correct as global.

---

TBH global vs project config is confusing even to me after 5 years of contributing and maintaining Jest 😅

[SimenB]

Preset fixed in https://github.com/facebook/jest/releases/tag/v29.3.1.

It's midnight here now, so I'll need to revisit tomorrow and verify what's the correct behaviour for the other fields. Even if it makes sense that a certain option is a project config and not global, we need to look at what the behaviour is first - that can only change in the next major. But if more fields are wrongly warned about, we should fix that.

I'm still getting some warnings like this post jest-config 29.3. Forcing it to <29.3 removes the validation messages.

[MichaelBorde]

I can confirm this works for preset option.

[Angeart]

I'm getting same error on >29.3

● Validation Warning:

  Unknown option "collectCoverageFrom" with value ["<rootDir>/components/**/*.vue", "<rootDir>/pages/**/*.vue"] was found.
