Suggestion

Some RuleTester tests in this repo are generated dynamically. Auto-generating tests like that can help create comprehensive test coverage for rules - but:

• They tended to exponentially grow in size as more cases get grown
  • This is especially bad for slow typed tests: e.g. Tests: Reduce the giant number of naming-convention tests #9691
• They make it hard to see what cases are or aren't being tested
• They're not very statically analyzable

We'd like to move away from these auto-generated / dynamic test cases. That specifically means making all test cases passed to RuleTester be completely inline plain old JavaScript objects. No .flatMaps/.maps, no dedupeTestCases, helper functions, etc.

This issue tracks doing so for packages/eslint-plugin/tests/rules/no-base-to-string.test.ts.
