そのコード、失礼かもしれません。

"use strict";

const rule = require("../rules/no-else");
const RuleTester = require("eslint").RuleTester;
const ruleTester = new RuleTester();

const valid = [
	{
		code: "if (a) { console.log(); } else {};"
	}
];

const invalid = [
	{
		code: "if (a) { console.log(); };",
		errors: [
			{
				message: "elseを省略するのは手抜きコードと思われ失礼です。",
				type: "IfStatement"
			}
		]
	}
];

ruleTester.run("no-else", rule, { valid, invalid });
