I want to cover this scenario, but I assume the redisURI is not pointing to a Redis Cluster.

import {Cluster} from 'ioredis';

test.serial('should support cluster instance', t => {
	const cluster = new Cluster([{ host: redisURI }]);
	const keyv = new KeyvRedis(cluster);

	t.is(keyv.redis, cluster);
});
