feat: rule tester add assertion option `requireData` by DMartens · Pull Request #20409 · eslint/eslint

DMartens · 2025-12-22T16:25:45Z

Prerequisites checklist

I have read the contributing guidelines.

What is the purpose of this pull request? (put an "X" next to an item)

[ ] Documentation update
[ ] Bug fix (template)
[ ] New rule (template)
[ ] Changes an existing rule (template)
[ ] Add autofix to a rule
[ ] Add a CLI option
[ ] Add something to the core
[x] Other, please explain: A new assertion option for the rule tester

What changes did you make? (Give an overview)

Add the assertion option requireData: boolean | "error" | "suggestion" which requires data to be set for error or suggestion matchers when the message referenced by messageId has placeholders.
It allows using error and suggestion shorthands (e.g. errors: 1 or suggestions: 2).
Fixes #20390.

Is there anything you'd like reviewers to focus on?

Please double-check the wording in the error messages and the documentation.
I extended the check whether the rule specify messages to include requireData.
Should this check be separate and more specific to also throw an error if all messages in rule.meta.messages have no placeholders?

Should this check be separate and more specific to also throw an error if all messages in rule.meta.messages have no placeholders?

I think it shouldn't throw an error. The assertionOptions settings could be shared between tests for multiple rules, and if some of them don't have placeholders in their messages, I think requireData shouldn't matter for those rules.

LGTM, thanks! Since this is a new feature, it needs a second review before merging.

The logic LGTM. Can we update the type tests with requireData?
