Using dynamic import returns a Promise, so ESLint will receive a Promise instead of the actual config object. Consider using a synchronous require('eslint-config-godaddy') or convert this file to ESM with top-level await to ensure the config is resolved before extending.

Suggested change

	const GDConfig = import('eslint-config-godaddy').then((mod) => mod.default || mod);
	const GDConfig = require('eslint-config-godaddy').default || require('eslint-config-godaddy');

Calling mock.reset() may not restore overridden methods or clear all mock state. Use mock.resetAll() and mock.restoreAll() (or the appropriate sandbox instance methods) to fully clean up mocks between tests.

Suggested change

	mock.reset();
	mock.resetAll();
	mock.restoreAll();
