1. Use ESLint API instead of CLI to run test
2. Improved log
3. Speed up by spliting into groups

The ts parser is so damn slow, took 11min to lint 500 files https://github.com/sindresorhus/eslint-plugin-unicorn/actions/runs/3089488168/jobs/4997163035#step:5:83

Missing ruleId in message eslint/eslint#16333

Missing ruleId in message eslint/eslint#16333

Mistake, there is no ruleId if it's a syntax error https://github.com/eslint/eslint/blob/2c152ff0fb709b99e62c19ecd2c95689efacbe4c/lib/linter/linter.js#L845, I guess ESLint can't trace which rule cause that invalid fix.

Very nice! 🎉
