The other way is to do in your class static function getRedis and mock it. For example:

let redis = {
   createClient: function() {},
};
let connection = {
   saddAsync: function() {},
   spopAsync: function() {},
};
let saddStub = sinon.stub(connection, 'saddAsync');
sinon.stub(redis, 'createClient').returns(connection);
sinon.stub(Redis, 'getRedis').returns(redis);

expect(saddStub).to.be.calledOnce;

Inside your class connect function looks like:

this.connection = YourClass.getRedis().createClient(port, host, optional);
