feat(eslint-plugin-internal): [no-multiple-lines-of-errors] add rule by JoshuaKGoldberg · Pull Request #11899 · typescript-eslint/typescript-eslint

JoshuaKGoldberg · 2025-12-29T06:30:17Z

PR Checklist

Addresses an existing open issue: fixes Repo: Internal lint rule against multiple errors across multiple lines in tests #6664
That issue was marked as accepting prs
Steps in Contributing were taken

Overview

Adds and enables the lint rule internally. There were pleasantly surprisingly few existing reported cases. I cleaned up the ones that could be, and ignored the others where the rule needed it.

Extracts a shared getRuleTesterCallObject to reuse the logic from no-dynamic-tests.
